ABSTRACT
This chapter reviews some popular methods and how the correct application of a model can lower the complexity of an image analysis task. The best-known format is RGB which encodes the color as three channels. The channels are red, green, and blue. The first image corresponds to the red channel, and the pixels that are bright in this image contain significant red contributions. So obviously, the bird's body is brighter in this channel than it is in the others because it is red. Those same pixels are darker in the other two channels. In the RGB format, the intensity of a pixel is mixed in with its hue, and this creates a difficulty in many analysis techniques. The first model considered is hue, saturation, value (HSV). The HSV color model represents data in three channels known as hue, saturation, and value. The models other than RGB attempt to isolate the intensity information from the hue information.
