In this paper we describe a 2D wavelet transform (WT) implementation intended for color image compression. The proposed implementation handles the data stream on the YUV color space thanks to a multicomponent approach of the wavelet transform. The 2D WT is conducted in a separable manner by means of the 5-3 biorthogonal filters. This leads to a multiplier-less and low-latency on-line running computation, realization of a 2D multicomponent forward and inverse discrete wavelet transform (DWT) on a single FPGA chip.
