VLSI Implementation of Modified Guided Filter for Edge Preservation

Filtering is widely used in the image and video processing application for various technology. Field Programmable Gate Array (FPGA) technology has become a viable target for the implementation of real-time algorithms is suitable for the video image processing applications In this paper a explicit image filter called guided filter is proposed to remove the noise in images smoothing and sharpening of images .We proposed the systolic array architecture for modified guided filter. The guided filter is derived from the local linear model computing the filtered output by considering the content of guided image can be the input image or different image. The guided filter can be using as the edge preserving smoothing operator. Transfer the structure of filtering image to the filtering output enabling and filtering application like dehazing and guided feathering. Computer vision and computer graphics applications, include edge-aware smoothing, HDR compression, image matting. Avoid halo effect using the weighted least square filter. FPGA can be used to implement any logical function that an ASIC could perform. VLSI Implementation for modified guided filter to achieve the high speed, low power consumption and reduce area.
