Abstract
The present disclosure provides an image processing method, device, and computer readable storage medium, relating to the field of image processing technology, the method includes: acquiring a first undersampled image to be processed; and reconstructing, according to a mapping relationship between an undersampled image and a normally sampled original image, the first undersampled image to a corresponding first original image, wherein the mapping relationship is obtained by training a machine learning model with a second undersampled image and a normally sampled second original image corresponding to the second undersampled image as training samples.
Claims20
An image processing method comprising:
- acquiring a first undersampled image to be processed;
- and
- reconstructing, according to a mapping relationship between an undersampled image and a normally sampled original image, the first undersampled image to a corresponding first original image, wherein the mapping relationship is obtained by training a machine learning model with a second undersampled image and a normally sampled second original image corresponding to the second undersampled image as training samples;
- the image processing method further comprises:
- downsampling the second original image to obtain the second undersampled image, comprising:
- downsampling the second original image to obtain a second downsampled image, and
- upsampling the second downsampled image to obtain a second upsampled image of the same size as the second original image, wherein the second upsampled image is used as the second undersampled image;
- and
- training the machine learning model with the second undersampled image and the second original image as training samples to obtain the mapping relationship.
