基于平均区域划分的Laplacian稀疏编码的图像分类
IMAGE CLASSIFICATION BASED ON AVERAGE REGION PARTITIONING AND LAPLACIAN SPARSE CODING
摘要
Abstract
For the sparse coding method, the coding process is unstable and the pyramid matching method can not make the fusion feature very sparse, an image classification method based on Laplacian sparse coding with average region partition is proposed.Firstly, local invariant feature transform (SIFT) feature extraction was applied to the original image.Then, Laplacian regularization was added to the sparse coding method to encode the local features so that the similar features have similar code words and the feature vectors were fused by average region partition and max pooling.Finally, multi-class SVM classifier was used to classify the images.Experimental results on several standard image datasets show that the algorithm has higher classification accuracy.关键词
