摘要

提出了一种基于序列中数据元素字节长度变化的无损压缩方法。该方法在图像压缩领域得到了发展和分析。创建该算法的目的是为了简化图像压缩的硬件实现,节省硬件面积和内存资源。与JPEG编码相比,采用不同的量化方法,经过DCT变换后使用。将该算法的压缩结果与JPEG压缩结果进行了比较。

Variable byte-length data compression algorithm
The paper presents a lossless compression method, based on the variation of the byte length of data elements in the sequence. The method has been developed and analyzed in the field of image compression. The purpose of creating such an algorithm was to simplify the hardware realization of the image compression and save hardware area and memory resources. It is used after DCT transformation along with different quantization method comparing to JPEG encoding. Results of the algorithm are compared to JPEG compression results.
