Abstract :

The real time implementation of guided filter highlights the implementation of Guided filter for image and video using VLSI hardware incorporated with real time application. The filter implementation is done with the use of guided image as reference image. A 30 frames/second video is given as input to this architecture and is separated into frames. These frames undergo preprocessing, noise analysis, smoothing of noisy pixels, and enhancement of edge level pixels by using MATLAB. Both color images as well as gray images are simulated by reformation of parameters in the guided filter formulae. Here the double integral image hardware architecture for the guided filter is proposed using FPGA controller by making use of Xilinx Platform Studio and Visual Basic. The guided filter simulation done using MATLAB is extended to build an architecture using Xilinx Platform Studio and FPGA Controller. With the help of the hardware implementation using FPGA there will be additional benefits like better performance at edges and suppression of color noise while preserving edges. This structure can support full HD 30 frames/second at a reduced gate count and chip memory. Guided filter is the ideal option since it performs better at the edges and suppresses color noise while preserving structures and as a result it is widely adopted in the field of computer vision and computational photography.
