Colorization-based image coding is a new color image compression technique which compresses the color information of a color image into a small set of representative pixels (RP).
In general, there is academic support for the IBGE classification system, which is the only source of information on color categories at a national level [3], [4].
Due to high correlation of information of I color channel with YCbCr color channels, only PDFs of HSI color space is used for recognition process by using KLD as it was mentioned earlier.
Despite the high information content of color iris images and economical aspect of VL cameras, the iris images acquired under the VL illumination are prone to unfavorable effects of environmental illumination.
Although the linear RGB color remapping method (18) provides an efficient way to preserve the color information of the input color, YCbCr is the most commonly used color space to render video stream in digital video standards.
According to actual picking environment of Lingwu long jujubes, this paper finds the rules between hue of Lingwu long jujubes and the surrounding environment and extracts hue information of true color image.
Then, it extracts hue information of true color image and uses maximum entropy for image segmentation, judging accuracy of image segmentation by segmentation area whether it is in accordance with the 3σ principle.
Once any skin region has been designated (touched) by the user's finger, the information of skin color and screen coordinate of the touched point are sent to the TCH algorithm together for skin detection.
