摘要
将图象分为非连续分量和连续分量,并模拟大脑对物象的方向滤波处理特性,在对图象连续分量亚抽样压缩编码的同时,对其非连续分量采用方向滤波,获得带有图象主要边缘特征的方向图象,在保证图象质量的前提下,高效率地压缩了图象,提出了基于视觉特性和图象两分量模型的图象编码方法,对此作丁深入的分析和介绍,并在计算机上进行了模拟,取得了较好的效果。
Image field is divided into Discontinuous Component and Remainder Component, and the human process is imitated. When the Remainder Component is sub-coded, the Discontinuous component passes through direction-filters and the direction-images are gotten. The image data are compressed and high ratio is gotten with good image quality. This paper introduces the image coding method based on the recent progress in the brain mechanism of vision and the two-component model of the image, and gives a description of relevant techniques.
