RGB 和 HSV 颜色转换

This line of code converts the color space of a frame from BGR (Blue Green Red) to HSV (Hue Saturation Value). The HSV color space is often used in computer vision applications because it separates the color information into three components that are more intuitive and easier to work with than RGB or BGR.
The three components of HSV are:
1. Hue: This represents the color itself, and is measured in degrees from 0 to 360. Red is 0 degrees, green is 120 degrees, and blue is 240 degrees.
2. Saturation: This represents the intensity of the color, and is measured as a percentage from 0 to 100. A saturation value of 0 means the color is grayscale (no color), while a value of 100 means the color is at full intensity.
3. Value: This represents the brightness of the color, and is also measured as a percentage from 0 to 100. A value of 0 means the color is black, while a value of 100 means the color is at full brightness.
By converting a frame to the HSV color space, it becomes easier to isolate specific colors or ranges of colors for further processing or analysis.
