In an HSV color space, H is for hue, S is for saturation, and V is for value. Which of the following statements about the HSV color space are true?

• A.Saturation describes how vivid the color is. The lower the saturation, the closer the color is to gray. The higher the saturation, the more vivid the color.
• B.The HSV color space perceives colors differently from human eyes, so it is not suitable for image segmentation or color analysis.
• C.Hue indicates the basic color attributes, such as red, green, and blue.
• D.Value is a measure of brightness. The image brightness can be enhanced by processing the V component of the HSV color space.

• B.Semantic analysis is to analyze the structure of sentences and phrases to find out the relationship between words and phrases, as well as their functions in sentences.
• C.Syntactic analysis is to find out the meaning of words, structural meaning, their combined meaning, so as to determine the true meaning or concept expressed by a language.
• D.Lexical analysis is to find the lexemes of a word and obtain linguistic information from them.
