Embodiment Construction
[0039] The present invention will be further described below in conjunction with the accompanying drawings.
[0040] refer to figure 1 with figure 2 , a medical image super-resolution reconstruction method based on multi-attention residual feature fusion, combining channel attention and spatial attention modules, weighting the features of the input image from multiple aspects, plus local and global residuals The features are fused and a novel super-resolution reconstruction method is constructed, including the following steps:
[0041] 1) Processing of training samples:
[0042] In order to make the proposed super-resolution network model have corresponding high-resolution images (i.e. HR) and low-resolution images (i.e. LR) in the retraining process, the present invention first performs a high-definition medical image original data set with a resolution of 512x512. 2x and 4x bicubic downsampling, resulting in low-resolution datasets at 256x256 and 128x128 resolutions.
