Adaptive Laplacian Filtering Interpolation Scaling Algorithm

In the field of video display, with the increases of resolution, the problems of transmission bandwidth, display adaptation and image display quality have gradually become prominent. To solve the above problems, we propose a new adaptive filtering interpolation scaling algorithm composed of an adaptive Laplacian filter and a bilinear interpolation scaling algorithm. The Laplacian filter alleviates the blurring effect of bilinear interpolation and enhances the image edges. Furthermore, an adaptive technology is used to enhance the effects of Laplacian filters. Bilinear interpolation was chosen for its simplicity of computation and good quality of scale. Experimental results show that compared with other methods, the average peak signal-to-noise ratio of the proposed is 0.64 dB higher than the bilinear interpolation scaling algorithm, and the calculation process is simpler.
