Image Recognition Algorithm Based on Information Fusion Combining Sparsity and Synergy

With the rapid development of information science and technology, image recognition technology plays an increasingly important role in the field of information security. However, in practical application, image recognition is easily affected by factors such as illumination, occlusion, background and other non-ideal conditions, so it is of great practical significance to seek robust image recognition technology. Sparse representation and collaborative representation can capture the essential features of face image, and obtain better recognition effect in image recognition. Therefore, this paper proposes an image recognition algorithm based on information fusion of sparsity and synergy. Experiments are carried out on the problems of collaborative representation classification and single sample image recognition. Experimental results show that, compared with sparse representation classification, collaborative representation classification achieves higher classification accuracy. When part of the pixel value image is occluded by 10%, the recognition rate of sparse representation algorithm is 99.1%, and the recognition rate is very good. Both algorithms have achieved very good recognition results in image recognition. Experiments show that sparse representation algorithm and collaborative representation algorithm improve the recognition rate of images.
