应用于视皮层假体的图像压缩算法的研究

Pre-image compression plays an important role in the visual cortex prostheses, which have become a main approach to restore the vision. This paper discussed an image compression algorithm for visual cortex prostheses by combining with the visual characteristics of the human eyes. A method of transform the visual angle into image pixel was proposed and then a non-uniform compression model was established in this article. Variable resolution in different regions was compressed using this model. Variable resolution compression method, which can achieve the effective delivery of visual information by using the finite point array, makes the image process much closer to the visual process than the traditional uniform compression method.
