Simple bit-plane coding for lossless image compression and extended functionalities
Hisakazu Kikuchi, Kunio Funahashi, Shogo Muramatsu · 2009
A simple lossy-to-lossless bit-plane coding of still images is presented to integrate several functionality extension including selective tile partitioning, progressive transmission, ROI transmission, accuracy scalability, and others. The mean squared error between the original image and a decoded image at any progression level is known prior to encoding/decoding. The proposed bit-plane codec is competitive with JPEG-LS and JPEG 2000 in the lossless compression of 8-bit grayscale and 24-bit color images. The codec outperforms the existing standards in 8-bit color-quantized image compression.
