| Summary: | 碩士 === 國立臺灣大學 === 電機工程學研究所 === 91 === The image data compression technology has very important position in our life. There are many image compression algorithms created for the request of the people. We need different image compression technology for a variety of applications. This thesis is mainly aimed at the lossless image data compression technology. We analyze following lossless compression algorithm lossless JPEG, JPEG-LS, CALIC, Lossless JPEG-2000 and PNG. The result show that JPEG-LS is a good compression algorithm.
For the business application purpose, the lossless image compression algorithm JPEG-LS have the advantage of low cost and high compressed ratio. In this thesis, we introduce the JPEG-LS algorithm and we also design the JPEG-LS encoder for the application of some independent system. The design strategy is modular design for easy maintain . And share the module to reduce the gate count and increase the circuit utilization.
