Digital Image Progressive Fusion Method Based on Discrete Cosine Transform

The current progressive fusion methods for digital images have poor denoising performance, which leads to a decrease in image quality after fusion. Therefore, new method was proposed based on discrete cosine transform, and its effectiveness verified through experiments. experimental results show that the has PSNR value higher than 42.13 db fusion, both of are comparison method, effect also quality. In terms time, time research is lower when data volume between 10 100, while structural similarity, similarity fused by always 0.83. Overall, study effective great significance practical
