Embodiment

[0029] Below in conjunction with accompanying drawing, further describe the present invention by example, but do not limit the scope of the present invention in any way.

[0030] The present invention takes the RESIDE data set as an example, and the specific operations are as follows:

[0031] Step 1: Use the RESIDE dataset, which contains training sets and test sets;

[0032] Step 2: Send the foggy image x in the training set as input to the generator G to generate G(x), that is, the fog-free image

[0033] Step 3: Convert the generated fog-free image to Send it to the discriminator D to judge whether the picture is true or false;

[0034] Step 4: After 200 iterations, the optimal generation model is obtained;

[0035] Step 5: Apply the obtained optimal generation model to real foggy images for dehazing processing.

[0036] In this implementation, the generator is composed of three parts: encoder, converter and decoder; the encoder is composed of 3 layers of convolutio...

Abstract

The invention relates to a road scene defogging method based on a conditional generative adversarial network. The road scene defogging method comprises the following steps: 1) constructing a trainingset and a test set by adopting a RESIDE data set; 2) taking the foggy picture x in the training set as the input of a generator G and generating G (x), namely a fogless picture; 3) sending the generated fogless picture to a discriminator D to judge whether the picture is true or false; 4) obtaining an optimal generation model after iteration setting for rounds, and 5) applying the obtained optimalgeneration model to a real foggy image for defogging. Compared with the prior art, the method has the advantages of good robustness, short processing time and the like.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a road scene defogging method based on a conditional generation confrontation network. Background technique [0002] With the development of computer vision and its application in the field of traffic and security monitoring, image defogging has become an important research field of computer vision. Under severe weather conditions with low visibility caused by fog and haze, the pictures collected by the camera are affected by suspended particles in the atmosphere (such as fog, haze, etc.), resulting in poor picture quality, and it is difficult to distinguish the characteristics of objects in the picture, and even Affects image quality in applications such as outdoor surveillance, object recognition, and traffic navigation. Therefore, the definition of foggy image features has important research significance. [0003] At present, there are two main categories of image d...
