摘要:	由於比特犬的攻擊事件頻傳，比特犬其特有的生理條件以及長期被培育成殘忍的鬥犬，因此傷人或傷犬的事件時有耳聞，受害者等特定團體因而要求政府全面禁養，目前世界上有數十個國家已將比特犬列為管制犬種，而台灣也將與國際接軌，目前已預告將比特犬列為管制輸入，禁止從其他國家進口到台灣，已飼養的比特犬雖可繼續飼養，但需要登記與列冊管理，而不得任意繁殖與販售。要從源頭管理禁止輸入比特犬，則必須建立完善邊境管理方式，目前一般國際間的海關通常是以外觀作為犬種鑑定，但由於人的肉眼判斷標準不一致，容易出現爭議，若能以犬隻影像建置一套辨識系統，則能夠避免人為判斷的爭議，故本研究希望能以AI方式辨識比特犬，以動物的生理特徵結合電腦視覺來辨識，在訓練過程中需要大量的比特犬影像，首先將影像去除背景擷取出比特犬的影樣，接著以三種神經網路辨識比特犬，分別是殘差神經網路、孿生神經網路以及殘差神經網路與孿生神經網路組合的方式，三種實驗結果顯示以殘差神經網路的方式辨識比特犬的效果最佳。 ;Due to frequent attacks of pit bulls, pit bulls have special physical conditions and long-term bred to be cruel fighting dogs. Incidents of hurting people or dogs are heard sometimes, some groups of victims require the government to ban pit bulls. At present, many countries in the world have listed pit bulls as a controlled dog breed, Taiwan will be in line with international standards. It has been announced that Taiwan bans pit bulls imports from other countries. Those pit bulls have been bred that can be bred, but they need to be registered and managed. Pit bulls cannot be arbitrarily bred and sold in the future. To efficiently ban the import of pit bulls from other countries, it is necessary to establish border management methods. At present, international customs usually use appearance as the recognition of dog breeds, human judgment is inconsistent and may cause controversies. The controversies of human judgment can be avoided if we establish efficient recognition system with pit pull-type dogs′ image. Therefore, this study will use AI biometric identification to recognize pit bulls with computer vision, a large number of pit bull images are needed in the training process. The background image is removed and the dog image is cropped, and use three different neural networks to recognize pit bulls. There are Deep Residual Network, Siamese Network and the above network combination method. The best result of three methods is to use the Deep Residual Network to recognize pit bull.
