Embodiment Construction

[0046] 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.

[0047] Such as figure 1 Shown, in one embodiment, a kind of processing method of RGB color image comprises such as step:

[0048] Step 110, acquiring the RGB color image to be processed.

[0049] In this embodiment, an RGB color image will be used as input, wherein raindrops will cover any area in the RGB color image.

[0050] Step 130, convert the RGB color image to be processed into YPbPr color space.

[0051] In this embodiment, the YPbPr (color difference component interface, which is the logo of the analog system) color space, YPbPr is the analog component video signal, wherein, Y refers to...

Abstract

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

Description

technical field [0001] The invention relates to image processing technology, in particular to a processing method and system for 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, brightness difference between frames, HSV 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 ...
