Embodiment Construction

[0043] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0044] Such as figure 1 Shown, in one embodiment, a kind of method for processing RGB color image, comprises the steps:

[0045] Step 110, acquiring the RGB color image to be processed.

[0046] In this embodiment, an RGB color image will be used as input, and raindrops will cover any area in the RGB color image.

[0047] Step 130, convert the RGB color image to be processed into HSL color space.

[0048] In this embodiment, HSL obtains various colors by changing the three color channels of hue (H), saturation (S), and lightness (L) and superimposing them with each other. Among them, the H(hue)...

Abstract

The invention provides a method and system for processing an RGB color image. The method comprises: obtaining a to-be-processed RGB color image; converting the to-be-processed RGB color image into an HSL color space unit; obtaining an L channel value by using the HSL color space unit obtained by conversion and carrying out rain removing processing on the L channel value to obtain an L channel value after the rain removing processing; and restoring an HSL color space unit containing the L channel value after the rain removing processing so as to obtain an RGB color image after the rain removing processing. With the method and system, raindrop removing on the RGB color image is realized.

Description

technical field [0001] The invention relates to image processing technology, in particular to a method and system for processing RGB color images. Background technique [0002] With the development of image processing technology, the research on the characteristics of raindrops in video images and the research on rain removal algorithms have also received extensive attention. For example, the median calculation method originally proposed has been rapidly developed, and the method for processing raindrops in video images is no longer limited to this simple median calculation method, and can also be calculated by skewness calculation, K-means Various methods such as clustering, Kalman filtering, dictionary learning, sparse coding, guided filtering, inter-frame brightness difference, HSL space, optical flow, and motion segmentation have also been gradually applied to raindrop removal in video images. [0003] However, these traditional raindrop removal methods are aimed at vid...
