the exi format uses a hybrid approach drawn from the information and formal language theories, plus practical techniques verified by measurements, for entropy encoding xml information.
exi格式使用一种源于信息和正式语言理论的混合方法以及经过测量验证的实践技术对xml信息进行熵编码。
using the sparsity of the scene, pixels above the threshold were mapped to a triple before entropy encoding for both grayscales and locations.
利用场景的稀疏性,将阈值以上的像素映射到三元组,对其灰度和位置信息分别熵编码;
the project is based on wavelet transform image compression, and implements wavelet transform, subband coding, the quantization and entropy encoding processes provide data compression;
该方案基于小波变换的场内图像压缩技术,采用小波变换、子带编码、自适应量化和熵编码来对图像数据进行压缩;
