Problems solved by technology

The representative literature of this type of method is [1,2]. However, these methods focus on processing uniform motion blur [1] or Gaussian blur [2]. When applied to more complex non-uniform motion blur scenes, the results are far from Can not meet the actual application needs

Embodiment Construction

[0038] The present invention is further described below in conjunction with accompanying drawing:

[0039] A fusion network-based image super-resolution and non-uniform blur removal method, comprising the following steps:

[0040] Step 1: Preprocess the original video and obtain the image training data set: convert several segments of video collected by the high-speed motion camera into multiple pairs of spatially aligned image block triplets{l blur , l, h}, where l blur Indicates the non-uniform motion blurred image block at low resolution, which is used as the input of neural network training; l and h represent the clear image block at low resolution and the clear image block at high resolution, respectively, which are used as the true image of different branches in neural network training. value;

[0041] Step 2: Build a deep neural network: The neural network uses two branch modules to extract features for image super-resolution and non-uniform blur removal, and adaptive...

Abstract

The invention discloses a natural image super-resolution and non-uniform motion blur removing method based on a depth feature fusion network, which firstly realizes the restoration of a low-resolutionnon-uniform motion blur image based on a depth neural network. The network adopts two branch modules to extract features for image super-resolution and non-uniform blur removal respectively, and achieves adaptive fusion of the outputs of the two feature extraction branches through a feature fusion module that can be trained. Ultimately, the upsampling reconstruction module realizes the task of removing non-uniform motion blur and super-resolution. This method utilizes the self-generated training data set to train the network offline, thus realizing the restoration of low-resolution non-uniform motion blurred images of any input size. This method has low training difficulty, good effect and high computational efficiency, is very suitable for image restoration and enhancement of mobile devices and monitoring equipment.

Description

technical field [0001] The invention belongs to the field of computer vision and image processing, in particular to an image super-resolution and non-uniform blur removal method based on a fusion network. Background technique [0002] Image super-resolution is a class of fundamental tasks in computer vision applications. Its purpose is to restore high-resolution images from low-resolution images, improve image quality and restore image detail information. It can not only generate satisfactory high-resolution images, but also provide higher-quality image sources for deeper image processing processes such as target detection and face recognition. However, there are moving objects of different depths and motion occlusion in natural images, so non-uniform motion blur often exists in real low-resolution images, which will seriously affect the research of super-resolution algorithms. [0003] Unlike uniform motion blur images, non-uniform motion blur images are fused from adjace...
