Embodiment Construction

[0031]In order to make the objects, technical solutions, and advantages of the present invention, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. The depth learning in the article refers to the artificial neural network composed of many layers, and "deep" refers to the number of hidden layers in the neural network. Use the neural network to simulate the human brain to process the data.

[0032]Batch normalization (BN) is for deep neural networks, with network training, the adjustment of the front layer parameters makes the distribution of the latter input data change, and the layers need to be continuous in the process of training. Change to adapt to learning this new data distribution. Batch normalization is used to reduce the changes in internal data, which can greatly speed up the training of depth neural networks, reduce gradient dependence on parameter scale or initial value, and solve the loss of lear...

Abstract

The invention discloses a rain removal system based on a dual-channel multi-scale discrimination model and a control method, the system comprises a generator and a dual-channel multi-scale discriminator, the generator is used for generating an adversarial network, the generator is composed of a multi-scale feature extraction unit and a dense connection unit; the multi-scale feature extraction unit is used for acquiring a receiving field and acquiring multi-scale rain mark information according to scale input; the dense connection unit is used for removing a rain layer and reserving a background layer; and the dual-channel multi-scale discriminator is provided with a dual-channel discrimination module, and the dual-channel discrimination module is used for judging whether the output rain-removed image and the real rain-free image are true or false. The influence of raindrops on images is solved by utilizing a dual-discrimination model generative adversarial network, the rain removal effect is enhanced, and the problems that images shot by a camera in rainy days are seriously degraded and the visual quality of the images is seriously influenced in the prior art are solved.

Description

Technical field[0001]The present invention relates to the field of computer visual, and more particularly to a dual-channel multi-scale discriminant model to rain system and control method.Background technique[0002]With the rapid development of science and the popularity of smartphones, mobile phones and cameras are severely degraded in rainy days, seriously degraded, seriously affecting image quality. In order to improve the overall quality of these degraded images, it is important to remove these undesired raindrops that have been enhanced and ensuring that the performance of the visual algorithm is enhanced. It is a very important issue that the raindrops that do not want to appear. .[0003]At present, the existing way to rain is divided into two categories: one is based on the rain, such as a high-frequency approach, assuming that the rain strip belongs to the high frequency component of the input image, and then learn from sparse coding and dictionary It is divided into rain and...
