Wavelet image compression techniques based on bit-plane adaptive binary arithmetic coding
【摘要】 介绍了一种基于位平面上二进制算术编码的小波图像压缩技术。把算术编码方法应用于位平面层次,根据数据的重要性对静止图像经过小波变换以后的量化系数在相应的位平面的数据位进行高效的自适应压缩编码,有效地解决了难以进行概率统计的信源的编码问题。压缩效率高于其他编码方法。
【Abstract】 A wavelet image compression techniques based on bit-plane adaptive binary arithmetic coding is presented. With application of arithmetic coding method to bit-plane hierachy, a high-effective adaptive compression coding for the quantization coefficient after wavelet transform of the stationary image is carried out on the corresponding bit-plane according to the importance of the data. Thus the coding problem of the information source that the probability statistics is difficult to be carried out is effectively solved. Its compression rate is higher than the other coding methods.
