市面上主要採用侵入式的RFID晶片方式進行犬隻身分識別，對犬隻健康造成疑慮，本研究以非侵入式的方式對犬隻做身分辨識，提出了一個多模態狗鼻紋身分辨識系統，分別使用局部二值模式（Local Binary Pattern，LBP）、灰階共生矩陣(Gray Level Co-occurrence Matrix, GLCM)、灰階梯度共生矩陣(Gray-Gradient Co-occurrence Matrix, GGCM）三個不同的紋理特徵提取方式來提取狗鼻紋理特徵向量，再將這三組特徵向量各別結合特徵分類器PNN (機率神經網路, probabilistic neural network - PNN)，得到三組最佳的推論機率後，將每一個模組的推論機率進行加權融合，看其辨識率，實驗結果顯示，使用本文提出的決策融合方法，比三種模態各自辨識率效果還要更好，在訓練資料30筆的情況下進行實驗，LBP結合特徵分類器PNN的辨識率為88%，GLCM結合特徵分類器的辨識率為79%，GGCM結合特徵分類器的辨識率為90%，而本文提出的決策融合PNN辨識率為100%；我們將訓練資料減少為10筆的情況下做實驗，LBP結合特徵分類器PNN的辨識率為75%，GLCM結合特徵分類器的辨識率為72%，GGCM結合特徵分類器的辨識率為80%，而本文提出的決策融合PNN辨識率為95%，因此可以證明多模態狗鼻紋身分辨識系統具有良好的辨識性能。;In the market, intrusive RFID chips are mainly used to identify dogs which causes doubts about the health of dogs. In this study dogs are identified in a non-invasive way. A multi-modal dog nose identification system is proposed. Using three different texture feature extraction methods LBP （Local Binary Pattern）, GLCM (Gray Level Co-occurrence Matrix) and GGCM(Gray-Gradient Co-occurrence Matrix) to extract dog nose texture feature vectors and then combine these three feature vectors with the feature classifier PNN(probabilistic neural network) to obtain the three sets of optimal inference probability. The inference probability of each module is weighted to see the recognition rate. The experimental results show that the decision fusion method proposed in this paper is more effective than the recognition rate of each of the three modes. It is performed with 30 training data. In the experiment the recognition rate of LBP combined with feature classifier PNN is 88%, the recognition rate of GLCM combined with feature classifier is 79%, the recognition rate of GGCM combined with feature classifier is 90%, and the recognition rate of decision fusion PNN proposed in this paper is 100 %. We reduce the training data to 10 experiments, the recognition rate of LBP combined with feature classifier PNN is 75%, and the recognition rate of GLCM combined with feature classifier is 72% GGCM binding recognition feature classifier was 80%, while the proposed decision fusion PNN recognition rate of 95%. It can be proved that the multi-modal Dog Nose Prints and Its Application in Pet Identity Identification has good recognition performance.
