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