Adaptive rate control for JPEG2000 image coding in embedded systems
暂无分享,去创建一个
To cope with the recent mobile scenes where images are used aggressively, a novel rate control scheme is proposed. The proposed scheme, dedicated for JPEG2000 image coding, aims at achieving low computational cost and small working memory size while maintaining high image quality. By predicting the adequate number of coding passes and updating it adaptively in code-block coding, the proposed scheme reduces both computational cost and working memory size for bitstream buffering down to 29% and 13%, respectively.
