Abstract
The invention discloses a baseline-based image super-resolution reconstruction method and a baseline-based image super-resolution reconstruction system. The baseline-based image super-resolution reconstruction method comprises the steps of: constructing a baseline-based convolutional neural network model; constructing an image super-resolution reconstruction model based on a conditional generativeadversarial network; and inputting a to-be-reconstructed low-resolution image into the baseline-based convolutional neural network model, taking the output of the neural network model as the input ofthe image super-resolution reconstruction model based on the conditional generative adversarial network, and finally acquiring a super-resolution reconstruction image. According to the baseline-basedconvolutional neural network model, two residual learning networks are stacked and used for learning high-frequency residual components which cannot be recovered by adopting a traditional image super-resolution method, and the quality of the obtained high-resolution image is improved by learning more residual information and constructing a CNN-based image super-resolution model.
Description
technical field [0001] The present invention relates to the technical field of computer vision, in particular to a baseline-based image super-resolution reconstruction method and system. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Image super-resolution reconstruction is an important branch of computer vision. It can obtain high-resolution images through the process of feature extraction, mapping, and reconstruction of low-resolution images through convolutional neural network models. Single image super-resolution is an important aspect of computer vision. The branch aims to generate a corresponding high-resolution image from a low-resolution image through a convolutional neural network. It has a wide range of applications in pedestrian detection, vehicle detection, face recognition and other scenarios. At present, the key problem to ...
