Title:
METHOD FOR TRAINING IMAGE ENHANCEMENT MODEL, IMAGE ENHANCEMENT METHOD, AND READABLE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/050731
Kind Code:
A1
Abstract:
The present disclosure provides a method for training an image enhancement model. The image enhancement model comprises an enhancement module configured to enhance brightness and contrast. The enhancement module comprises convolution branches corresponding to brightness intervals, and is used for inputting pixels of images inputted therein into the corresponding convolution branches according to the brightness intervals to which the pixels belong; convolution is performed by a first convolution unit in each convolution branch; and the images outputted by the convolution branches are merged and then convolved by a second convolution unit. The method comprises: inputting a sample image into the image enhancement model to obtain a result image outputted by the image enhancement model; calculating a loss, the loss comprising an image loss of the result image with respect to a standard image, and a first constraint loss of brightness histogram constraint of the images outputted by the convolution branches with respect to the standard image in each convolution branch; adjusting the enhancement module according to the loss; and if a training end condition is not satisfied, returning to the step of inputting the sample image into the image enhancement model. The present disclosure further provides an image enhancement method and a computer readable medium.
