Abstract: In this paper, we discuss parallel implementation of Wavelet Transform on multicore platforms. We compare performance of the wavelet transform implementation on different number of cores. We report the work carried out using Haar Wavelet. We have selected SciLab as our platform for experimentation. SciLab on Linux supports multiprocessing as function. Linux also supports enabling and disabling of cores. We use this feature to ensure the same environment for different number of cores. We compare the performance of the SciLabs inbuilt DWT function and our own function.

Keywords: Multicore, Parallel Algorithm, Wavelet Transform, Haar Wavelet
