Color image coding based on embedded wavelet zerotree and scalar quantization

With the continuous expansion of multimedia applications and the blossoming demand for efficiently storing and transmitting visual information, the needs and requirements of image compression have become increasingly vital. To address this need in the specific area of still image encoding, a new standard JPEG2000 is being designed. Our paper deals with color image coding using discrete wavelets transform, color embedded zerotree wavelet (CEZW) and combining scalar quantification and adaptive Huffman coding. The results are compared to JPEG2000 performances using the JAVA implementation.
