find rgb color from image

Transferred from: http://blog.csdn.net/jiangxinyu/article/details/8000999General 3D programming only need to use RGB color space is good, but in fact, the art staff is more using HSV (HSL), because it is easy to adjust the saturation and

Mutual Conversion Between MATLAB Image Processing _ HSV and RGB color space, and MATLAB _ HSV The following code is a self-carried Conversion Function in matlab. It is posted here to facilitate future review and Study of Its Conversion

Needless to say, there is no technical content, because the following code is the self-contained conversion function in MATLAB. Posted here just to facilitate later review, study its conversion algorithm:HSV Space : H (Hue)--s (saturation)--v

HSV space: H (Hue)--s (saturation)--v (brightness)Similar to the HSI color space: H (Hue)--s (saturation)--I. (intensity)Attention:Intensity and brightness are almost a concept.Saturation represents the amount of light that penetrates into the white

1 PrefaceIn order to give color a quantitative measure, it is necessary to establish a color space model to describe a variety of colors, because people's perception of color is a complex process of physiological and psychological joint action, so

Although I have seen the introduction of color space several years ago, I did not write code to do this until today. Although there are already many examples available on the Web, one is only suitable for floating-point data, and on the other hand,

The data output format of the camera is generally divided into ccir601, ccir656, raw RGB and other formats. Here, the RGB format should be ccir601 or ccir656. The raw RGB format is different from the normal RGB format. We know that the sensor's
