一种数字图像的栅格矢量混合文件格式
File format of digital image in vector and raster data structure
摘要
Abstract
Based on self-adaptive non-uniform rectangular partitions of digital image, this paper defines a digital image file format in vector and raster data structure, which is called RV file format. This method self-adaptively stores different rectangular layers of the image in different forms, by which higher layers are stored in raster data structure, while lower layers in vector. It is space saving and has compression effect on digital image. The advantage of space saving is shown more obviously when it is used to store an image in huge size. Experiments are done to logo images in huge size to evaluate its compression capacity. The results show RV file format has obvious compression effect to digital image whose gray values distribute continuously in large area.关键词
