Image compression based on color morphological pyramidal decomposition

In this work, a pyramidal technique designed for color image compression is introduced, and, is based on a combination of a modified morphological pyramid and adaptive Vector Quantizer. This hierarchical structure gives an ability to produce high color image quality (35-48 dB) at low bit rates (0.1-0.9 bpp). The proposed scheme contains a multi-level pyramid based on modified morphological filters; then, the resulting pyramid levels are applied to a suitable 3D VQ encoder.
