Embodiment Construction

[0031] The present invention will be further described in detail below in combination with specific embodiments.

[0032] refer to figure 1 , single-component video image rain field removal includes the following steps:

[0033] The first step is to transform the image into the YCbCr color space according to the color attributes of the raindrops and in combination with the color space conversion;

[0034] The second step is to extract the Y component, and use the existing rain field removal method to remove raindrops;

[0035] The third step is to convert the image into the RGB color space by combining the unprocessed Cb and Cr components to complete the rain field removal.

[0036] refer to figure 2 , Compared with red light and green light, blue light has a larger refraction field of view angle, which is caused by the different refractive index of raindrops on red light, green light, and blue light. The longer the wavelength, the smaller the refractive index. However, t...

Abstract

The invention discloses a simple-component video image rain field removing method, which is characterized by comprising the following steps of: first converting an image into a YCbCr color space in combination with color space conversion according to the color attributes of raindrops; then extracting a Y component, and performing raindrop removal on the Y component by using the conventional rain field removing method; and finally converting the image into a red, green and blue (RGB) color space by combining Cb and Cr components. By the method, simple-component rain field removal is realized; and compared with the conventional three-component rain removing method, the invention saves the processing of two components and improves the real-time performance.

Description

technical field [0001] The invention relates to an image rain field removal method in the fields of computer vision and the like, and belongs to the technical field of image processing. Background technique [0002] Computer vision systems are widely used in the military field. However, the vision system has a critical problem - it is very sensitive to bad weather. Rainy weather often leads to reduced atmospheric visibility and reduced imaging quality of the visual system, which brings great difficulties to monitoring, navigation guidance, target tracking, and recognition systems that rely on the visual system. Restoring images in rainy weather is of great significance to the all-weather work of the vision system. [0003] After searching the literature of the existing technology, it is found that there is no invention patent on rain field removal in video images, and only a small number of scholars at home and abroad have carried out preliminary research on image rain rem...
