Other AbstractFor improving the quality of high resolution image and realizing the image enhancement algorithm ,an image en2 hancement algorithms is proposed. It enhances the image adaptive based on a cont rast measure defined within the Discrete Co2 sine Transform (DCT) domain. An improved classified method is proposed to classify the DCT mat rix in the image and the image is adaptive enhanced by using different weight in different type DCT mat rix. The algorithm is implemented on FPGA. It enhances the details in the dark and bright areas of image and get s rid of blocking artifact s. The algorithm uses low computa2 tions without affecting the compressibility of the original image ,and the experiment on FPGA result s show the satisfactory visual effect for computer and human vision.
