Title
DSP-based down-sampling process using lanczos filter bank
Abstract
Re-sampling process is the technique used to create a new version of the image with different width and/or height in terms of pixels count. It may be either increasing the size of image so called upsampling or reducing its size so called down-sampling. In this paper we interest on down-sampling process. Hence, a DSP TMS320C6472 implementation of the down-sampling module is performed. The down-sampling method is based on poly-phase filter bank. A software design for this poly-phase filter interpolation on two levels is proposed in order to satisfy a significant time saving. Results show the efficiency of the down sampler filter especially for removing the aliasing artifacts. A good speed performance is performed for the two implementation design. For execution time results, we might attaint a gain of 33 % for multi-core design execution compared with the one core design.
