The invention discloses a panda face recognition method based on limited training data. Firstly, the original panda image is input and manual panda face segmentation is performed, and the boundary detection is performed on the segmented panda face images to find the difference between each face image. Corresponding key points; extract panda face image features, align key points of all other images with the target image, use partial least squares regression as a classifier, and input positive and negative samples to train the classifier separately for each panda face image; Test with leave-one-out cross-validation to complete the establishment of the panda face recognition model. The present invention uses the edge of the face for algorithm execution, and uses partial least squares regression as a classifier, which can limit the number of pandas required and the number of training images for each panda, and is more helpful on the basis of the limited number of individual pandas and images. Accurate and efficient recognition of panda faces.
Description
technical field [0001] The invention belongs to the technical field of image analysis, in particular to the field of facial image recognition analysis of pandas. Background technique [0002] The giant panda (Ailuropodamelanoleuca) is a rare and endangered animal unique to my country and the flagship species of international wildlife protection. It is our duty and obligation to protect and breed giant pandas as "China's living fossils" and to promote the sustainable development of wildlife protection. The most basic and important work. In order to better and more effectively protect giant pandas, the state has conducted a national survey every ten years since 1974. So far, my country has carried out four national giant panda surveys. According to the results of the fourth national giant panda survey released by the State Forestry Administration in February 2015, by the end of 2013, the national wild giant panda population had reached 1,864, and the captive giant panda popul...
