摘要: Because of human abandonment and the lack of the concepts of neutering ,the problems of stray dogs are increasing. Stray dogs also derive many social problems, like infectious diseases, bite, influence on quality of life, etc. To deal with these problems, every country rounded up stray dogs and treated them in inhumane way before. And now, they use pet microchips pet collars, animal shelter, etc. to manage stray dogs. In this thesis, we propose a new management for stray dog and pets with computer technology. Because of the unique do nose prints we want to develope a system that can recognize d nose dog prints. The system consists of two parts: image segmentation and nose prints recognition In this thesis, we focus on the former part, segmentation of dog nose. First of all the proposed method uses image processing technology to enhance contrast of images. Then the appropriate features are derived from Gray Level Co-occurrence Matrix. According to those feature the background and nose region be identified from dog no images. Finally, Otsu's method is used to segment dog noses. In experimental results, the average precision, average recall and average F-measure are larger than 90%. And the average accuracy is higher than 88%.
由於人們棄養寵物及對結紮、節育觀念之缺乏,流浪狗的問題日益增加,並產生生許多社會問問題,如疾病傳染、打鬥及影響生活品質等。面對流浪狗之問題,各國從以前利用圍捕等不不人道的對待待方式,一直到現今常用之寵物晶片、寵物項圈、收容所等,加以規範管理流浪狗。因此,,我們提出一種利用電腦科技管管理流浪狗及寵物之方式,利用狗鼻紋之唯一性,欲欲發展一套狗鼻紋辨識系統,而辨識系統主要可分為兩個部分分:影像切割及鼻紋辨識,本篇主要研究於前者,將鼻子部位從狗鼻子影像中切割割出來。 首先,本篇利用影像處理技術將影像對比增強,接著使用 Gray Level Co-ooccurrence MMatrix 找出適合之特徵,將影像中背景與鼻子區域予以分辨。最後,利用 Otsu's 二用二值化方法將影像切割割出來。實驗結果顯示,本篇平均精確度、平均召回率及平均 F-measure 皆有達到 9皆90%以上,而平均準確性也達到88%以上。
