Abstract

A software library for computation of the discrete wavelet transform that is primarily implemented in C/C++ language and as well in other languages intended for target platforms (assembly languages). The library is designed for PC platform (basic and optimized implementation), embedded processor platform, and for hardware implementation (FPGA) and combined environment (EdkDSP) in future. The library implements fast wavelet transform algorithm using lifting scheme. Biorthogonal spline wavelets also known as Cohen-Daubechies-Feauveau wavelets of order of 4 (with 4 vanishing moments) were used. The library is implemented in C language, a demonstration application written in C++ and employing OpenCV (http://opencv.willowgarage.com/) library is enclosed.
