摘要: 本发明涉及一种面向边缘特征保持的图像压缩方法,具体地说是解决图像在低比特率压缩的同时,如何更好将图像边缘等特征保留下来的方法。本发明包括图像边缘检测、边缘编码、图像变换压缩编码、图像边缘保持重建。本发明优点在于有利于低比特率条件下重建图像保持完整的边缘特征,从而可以提高用户对重建图像的识别和理解程度。
英文摘要: The invention relates to an image compression method targeting at edge feature maintaining, specifically, a method which solves a problem of how to better maintain features of edge and the like of an image while the image is compressed at a low bit rate at the same time. The method includes image edge detection, edge coding, image conversion compression coding and image edge maintaining reconstruction. The advantages of the method are that maintaining of a complete edge feature of a reconstructed image under a condition of low bit rate is facilitated so that identification and understanding degrees of users of the reconstructed image can be improved.
