Research on Image Feature Information of Resisting JPEG Compression

摘要：

　　To solve the image feature information on the robustness of JPEG compression problems,we use the third layer of wavelet of images to decompose the approximation sub-band coefficients as the image feature information,analyze the characteristics of the discrete cosine transform in JPEG compression so as to compare the robustness of image feature information under different quality of JPEG compression.The experimental results show that:make the image compression quality factor more than the standard JPEG,the approximate sub-band coefficients of image wavelet as the image feature information has better robustness,and their difference is less than or equal to a smaller threshold.
