基于局部熵的圖像特征描述方法
[Abstract]:Using the traditional feature description method SIFT to describe the image features on a single scale will lose some important information, which will affect the correct matching results of the image. In order to solve this problem, the feature descriptors are extracted in multi-scale fuzzy space. Information entropy estimates the information of feature points and their surroundings from the point of view of image significance, and can obtain more key contents of image. In this paper, an image feature description method based on local entropy is proposed. Firstly, the multi-layer SIFT descriptors of feature points are calculated in Gaussian difference space (DOG), and the local entropy of feature points on each layer scale is counted, and the entropy value of feature points in each layer is calculated as a percentage of the total entropy of all layers, and the product of the obtained percentage and each layer narrator is made by using the obtained percentage; then, all layer descriptors are accumulated; finally, the final local entropy feature descriptors are obtained by using square root algorithm. The experimental results show that the local image description method proposed in this paper is robust in terms of accuracy-recall, average uniform accuracy and correct matching number.
