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。
The image is divided into non-continuous components and continuous components, and the direction of the brain to simulate the image processing characteristics of the continuous image sub-sampling compression coding at the same time, the non-continuous components of the directional filtering, with images The main edge features of the direction of the image, under the premise of ensuring the image quality, efficient compression of the image, based on the visual characteristics and image two-component model of the image coding method, this in-depth analysis and Introduced, and simulated on the computer, and achieved good results.
