In order to enhance the resolution of the image and improve the visual effect of the image, a method of image quality enhancement based on bilinear interpolation and wavelet transformation is proposed. The algorithm first enhances the image by histogram equalization and bilinear interpolation to preserve better detail quality, and then perform wavelet transform on the histogram equalized image and the original imageeach of the input images are devided into 4 subbands, estimates the singular value matrix of the low frequency subband image, and then enhances the image through Wavelet reconstruction, Finally, perform histogram matching on the result image and bilinear interpolation image to obtain an enhanced image. The experimental results show that the performance of the proposed method is better than that of the traditional method.
