Method for improving picture resolution and definition

The invention discloses a method for improving picture resolution and definition, and the method comprises the following steps: S1, carrying out the feature extraction of a blurred image: zooming the blurred image into a picture with a certain size, carrying out the feature extraction of the blurred image through a series of convolution down-sampling, and obtaining a series of feature maps from top to bottom; S2, reconstructing a high-definition image: performing up-sampling on a series of feature images from bottom to top through deconvolution, and finally gradually amplifying the size to the size of an original image; S3, feature mapping from the blurred image to the high-definition image: a series of feature maps from top to bottom obtained by feature extraction of the blurred image corresponding to a series of feature maps from bottom to top obtained by reconstruction of the high-definition image, that is, feature mapping from the blurred image to the high-definition image being carried out, and through a
