IDS模型在图象增强处理中的应用

Application of IDS model in image enhancement

本文讨论了一种基于人类视觉特性的新的图象增强处理方法,该方法利用了人类视觉系统中视网膜上光感受细胞所具有的扩布作用和视网膜上神经节的侧抑制效应.为了改善传统IDS只对图象边缘进行增强的局限性,我们对IDS点扩散函数进行了改进,使该系统能对整幅图象进行增强处理.

This paper describes a new method of enhancing images based on the character of human vision. This method mainly uses two functioas of human vistal system. One is the spreadout function of photoactive cell in retina,the other is the receptive field of gangilon cell in the retina which has lateral inhibition. In order to improve the limit of traditional IDS which only enhances the edges of the images, we improve the point-spread function of IDS ones more. As a result,it makesthe whole image enhanced.
