Title:
IMAGE SUPER-RESOLUTION METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/238558
Kind Code:
A1
Abstract:
The present invention provides an image super-resolution method and system. The method comprises: take an image to be processed as the input of a convolutional neural network super-resolution model, the convolutional neural network super-resolution model being composed of four execution modules which are connected in sequence; a first execution module processes said image to obtain a first processing image; a second execution module processes the first processing image and outputs a second processing image; a third execution module processes the second processing image and outputs a third processing image; a fourth execution module processes the third processing image and outputs a super-resolution image. Based on the present invention, the convolutional neural network super-resolution model sets the weighted features for said image, the important features in said image are determined by learning the weighted features, and the super-resolution processing is carried out according to the important features, so that the feature expression capability of the convolutional neural network super-resolution model is improved, and the detail quality of the super-resolution image obtained after the super-resolution processing is greatly improved.
