| Popis: | The color filter array(CFA) format image needs to interpolation to obtain the full color image.However,the interpolation algorithm of the CFA image is more complex,the image quality is higher,but the complexity algorithm will take more time to implementation,and it is inconvenient for real-time processing.This paper introduces two interpolation algorithm: the bilinear interpolation and edge oriented interpolation,and uses the FPGA hardware platform to realize the bilinear interpolation algorithm and the edge orientation algorithm,and analyzes two kind of algorithm with black and white stripes image.Conside-ring the edge direction,the edge oriented interpolation algorithm prevents the border interpolation,so the interpolation effect is better than that of the bilinear interpolation algorithm.Although the algorithm is some more complex,the optimized design of FPGA cache module,using parallel and pipiline processing mode,will fully meet the real-time requirements of engineering. |
