Résumé : The research presented in this thesis aims at determining the possibility of partial or total automatic ship detection in High Resolution optical satellite images. At first, we expose the industrial context of our study, which fixes the constraints in terms of performances and processing time. Then, we present the available satellite data for our study (SPOT 5 panchromatic images of 5m per pixel resolution). Then we detail our approach for ship detection : the first stage is a pre-detection of targets that gives us candidates. The second stage is a precise segmentation of each candidate and the third stage is a classification of candidates. Our pre-detection method is based on the Bayesian decision theory. This pre-detection supplies a set of regions of interests (ROI). Among them, we have ships, but also false alarms due to clouds and to crests of waves. The purpose of the following stage is to eliminate the false alarms and to characterize the pre-detected ships. Then, we detail the method used to segment candidates. It uses active contours and also uses the Bayesian decision theory. After a brief description of the characteristics extracted for the classication of ships, we present the classifier that we used. We complete the ship characterization by presenting two methods of wave ship detection. The first approach uses active contours and the second is based on an a contrario approach. We compare the results of these two approaches. To complete the study and replace it in the industrial and operational context, we present experiments of the complete algorithm on complete images to estimate the performances and the processing time of the whole method.
Les travaux présentés dans cette thèse ont pour but de déterminer la possibilité d'automatiser, partiellement ou totalement, la détection de bateaux à partir d'images satellitaires optiques haute résolution. Nous exposons tout d'abord le contexte industriel dans lequelle s'insère notre étude, qui fixe les contraintes en termes de performances et de temps de traitement. Puis, nous présentons les données satellitaires disponibles dans le cadre de notre étude (images SPOT 5 panchromatique de résolution 5m). Après avoir illustré le contenu des scènes, nous présentons la démarche adoptée pour la détection des navires : une phase de pré-détection suivie d'une étape de segmentation et d'une étape de classification. La méthode de pré-détection utilisée s'appuie sur la théorie bayésienne de la décision. Après avoir présenté le modèle classique, nous discutons du modèle que nous avons utilisé. Cette pré-détection fournit un ensemble de régions d'intérêts. Parmi elles, nous n'avons pas uniquement des bateaux, nous avons également des fausses alarmes dues aux nuages et aux crêtes de vagues. Le but de l'étape suivante est à la fois d'éliminer les fausses alarmes et de caractériser les bateaux pré-détectés. Ensuite, nous détaillons la méthode utilisée pour segmenter les bateaux. Elle s'appuie sur des contours actifs et utilise également la théorie bayésienne de la décision. Après avoir décrit les caractéristiques extraites pour la classification des bateaux, nous présentons le classifieur utilisé. Nous complétons la caractérisation des navires en présentant deux méthodes de détection des sillages différentes des méthodes classiques. La première approche s'appuie sur l'utilisation de contours actifs et la seconde est basée sur une approche a contrario. Nous comparons les résultats des ces deux approches. An de compléter l'étude et se replacer dans le contexte industriel et opérationnel de la thèse, nous présentons des expérimentations de l'ensemble de l'algorithme sur des images complètes pour évaluer les performances et le temps de traitement.

Résumé : The slides were taken on collecting trips sponsored by the William L. Bryant Foundation, where books, music and art indigenous to the regions were gathered. The are organized by geographical location.
Buildings near the harbor in Saint George’s, Saint George, Grenada. Many of the buildings’ architectural elements feature symmetrical designs. People can be seen walking along the harbor as automobiles pass by. Some of the retail establishments include “Jonas Browne & Hubbard Ltd.,” “The Royal Bank of Canada,” “The Nutmeg Bar & Restaurant,” “The Food Fair,” “BWIA,” and “Hankeys.” Jonas Browne and Hubbard Limited is a supermarket, which has been in business since the 1830s. Food Fair is also another supermarket chain. Trinidad and Tobago based BWIA, British West Indian Airways, was incorporated in 1943 by Lowell Yerex. The clock tower of Saint George's Anglican Church can be seen above the city. Saint George's Anglican Church was built in 1825 and suffered damage during Hurricane Ivan in 2004, losing its roof. The clock tower, constructed in 1904, still remains. Small boats can be seen in the harbor along with Merchant Vessel (MV) Geestcape, partially pictured, which entered service in 1966. In 1935, the Van Geest brothers in Spalding, United Kingdom started a horticultural business. The brothers later expanded their business to include a cargo service to carry horticultural produce, primarily bananas, from the Windward and Leeward Islands to Europe. Slide labeled Harbor + City Grenada.

British Guiana 1898 : Punishment for Sodomy meted out to Nabi Baksh and Mohangoo on the Mersey ; Report from the Governor to the Colonial Office
Auteur(s) : Walter Sendall Governor of British Guiana

Résumé : (Donation) This report was donated by Gaiutra Bahadur who came across it in when doing research for her soon to be published book "Coolie Woman" "Coolie Woman" is scheduled to be published in 2012 by The University of Chicago Press in the US and Hurst & Co. in the UK. An excerpt from the book first appeared in the Spring 2011 issue of the U.S. literary magazine The Virginia Quarterly Review (http://www.vqronline.org/articles/2011/spring/bahadur-coolie/) and was then reprinted in India in the Sept. 2011 issue of The Caravan magazine. The whole excerpt is up at the Caravan's Web site: http://www.caravanmagazine.in/Story/1058/Her-Middle-Passage.html
(Internal Comments) Notes from the Report Arrived October 31, 1898 Dr. Arthur Harrison, SS G.H. Rock, Captain 673 landed 436 men // 438 embarked 191 women // 192 embarked 19 boys 19 girls 8 infants 9 births 4 deaths, one a baby born on board 54 marriages 37 served before in BG, 21 in other colonies * measles epidemic early in voyage until they crossed the Equator, 38 days in, almost daily there were heavy squalls with rain; misery of seasickness, vessel pitching and rolling heavily * got to sea July 14 - the very worst month of the whole year, having to face the full force of the southwest monsoon, Sujaria's would have been the same timing the coal of inferior quality and ran short, meaning water and cooked meals less for immigrants surgeon's journal: july 28: no 167 baijooporai, m, 20, was reported missing at 3 p.m. [cause of death in death list "lost over board" no. 178 lachman states that on 25th instant at sunset baijoo was in his berth suffering from seasickness; later on he saw him take his blanket, get up and go away... lachman states baijoo was a very quiet well-behaved man, shewing no signs of mental aberration, but was very seasick. no further information could be obtained regarding his disappearance. from the emigrants or crew. ... september 25: "No 696, Nobibux, m., 20 years, and No 351 Mohangu, m, 22 years, were caught about midnight by a sirdar named Rambocus committing sodomy. When brought up before the Captain and myself they both confessed their guilt. Nobibux stated that for the last ten years he had allowed men to commit acts of beastliness: he had no doubt induced Mohangu to do this criminal act. Nobibux was put in irons and Mohangu, after blistering his penis, was made to holystone [scrub the decks] from 6 a.m. to 6 p.m. daily." [latitude 35.17 s. and longitude 22.10 e.] [nobibux handcuffed every night from sept 25 to landing on oct 31, as was a man who had jumped overboard and was rescued] criminal charges brought against two immigrants; in CO marginalia, discussion over the legality of the punishment and doubt expressed over whether there was any sodomy committed at all; indication there wasn't enough proof to prosecute: "the men should have been put in confinement and tried in British Guiana for an offense committed on the high seas on board a British vessel..."; fine the surgeon but should he be barred from re-employment? inspector general of police investigated; attorney general decided not to prosecute; IAG criticizes SS for punishing the two without fully and carefully enquiring into the case. violated Rule 165 relating to colonial emigration, which strictly prohibits harsh treatment of the people The contract with the surgeon superintendant enclosed shows that each was granted a pint of wine per day and stout. This surgeon was given 20 shillings per immigrant landed alive. for immigrants classified as invalids on embarking, if they died during voyage, he received a pro-rated amount, based on how long they lived; wife not allowed to go along. Arthur Harrison, SS, states on November 4, 1898: [on 25th Sept, when near the Cape of Good Hope, his compounder Abdul Wahed reported to him at 8 a.m. that he heard two men had committed sodomy during the night. he told the compounder to take the men to the hospital, where he would question them.] [witness, the sirdar Rambuccus, brought in with the two men. questioned in front of them, he said that he was on watch in between decks at midnight and "saw something unusual between these two men, they being under one blanket; he pulled off the blanket and saw them committing sodomy." he called the head sirdar at once. the prisoners denied it to the head sirdar but then later confessed. they were left in the charge of the hear sirdar for the rest of the night. captain also present at inquiry. while Rambuccus was giving this testimony, neither prisoner said anything.] [the head sirdar Salikram is then questioned. confirms being called as above. says he separated the men and "asked them why they were doing this wrong thing, that they at first denied it and afterwards they confessed they did it for pleasure."] [when questioned by SS, men at once confessed. Nabibux: "I have done it." Mohungu said same, "as far as I can remember. I cannot remember the words they used in confessing." Nabibux placed in irons fastened to a stanchion in the hospital. Mohangu placed in hospital and ordered to holystone from 6 a.m to 6 p.m. "I blistered the penis of Mohungu. I did so as a punishment as I thought he deserved it." did this right after enquiry concluded. the captain knew Harrison did this. "Mohungu was the man who committed the act on Nabibuccus. I blistered him as a preventitive, as he might have attempted the act again. I have known cases where the penis has been blistered as a preventitive treatment, in case of masturbation with boys."] [says he didn't see it as a crime committed against the laws of England, but "as a matter of discipline on board ship"; didn't examine their private parts for evidence] "Since this all occurred, it has come to my knowlegde that the head sirdar had threatend the two men to make them confess. Since I heard this, I have questioned them. Both denied the act and said Salikram had threatened to make them confess. My compounder's name is Abdul Wahed. I have heard from him since that the man Rambuccus who caught them had a spite against one of the men, owing to something that had occurred in the country Depot in India." ABDUL WAHED, THE CHIEF COMPOUNDER, STATES: [the inquiry occurred at about 8:30 p.m. on the 25th Sept.] "I heard Mohungu say he had put his penis in Nabibux' anus, and some days afterwards both men said to me that Rambux and Salikram had threatened to beat them throughout the voyage if they did not confess to having committed the sodomy." "Nabibux told me that he and Rambux had had a row in the Fizabad depot and he told me that Rambux had a spite against him." [the prisoners were under his charge in the hospital] [doesn't know what the depot quarrel was about. didn't ask. never noticed any ill feeling between Rambux and any of the men before this happened. never noticed Mohangu and Nabibux to be much in each other's company] RAMBUCCUS [an Ahir. says he knew Nabibuccus for a month in the Fyzabad depot, where he was a sirdar] "The men were under a platform sleeping. There were other coolies sleeping there too. The men were sleeping in their usual place... I noticed two men under one blanket. I have orders not to allow this, so I hauled the blanket off. Mohangu was on top of Nabibux who was lying on his back. Mahangu was lying on his stomach. I asked them what they were doing. They gave no reply. Mahangu came off. I did not see his private parts. His baba was loose. I did not notice the state of Nabibux' baba. He had it on, but I don't know whether the crupper of the baba was undone or not. I did not see his private parts. I did not see his anus. I did not see Mahungu's penis in Nabibux' anus, but from their position I suspected that they were committing sodomy... These two men always slept together during the voyage." SALIKRAM "They said Rambux hauled the blanket and shook them up while they were asleep. Rambuccus said they were committing sodomy but I don't think they were. They appeared to me just as if they had just been awakened. Their eyes seemed heavy with sleep." "I never knew either of these men before I met them onboard. Myself and Rambuccus do not agree. I never noticed Rambuccus and either of the two men have any quarrel. I never noticed Nabibux and Monungu keeping much company. I don't know whether these men were in the habit of sleeping alongside of one another. I never threatened these men to make them confess. I never heard the men confess they had done it. They did not confess before me." IN THE END: 50 pounds deducted from Harrison's gratuity for inflicting corporal punishment
