【Abstract】 According to characteristic of image wavelet transform and interpolation, this paper proposes an image interpolation method combining wavelet transform and interpolation algorithm, which can improve the image resolution. Experiments show that the algorithm can properly retain abundant high frequency information in original image. After interpolation processing and wavelet reconstruction, we can obtain an image with higher resolution, better visual effect, higher Signal Noise Ratio (SNR), more detail information and no apparent warp. Therefore, this algorithm is an effective method of super resolution image processing.更多还原
