Of all the different image formats that the Vision Toolkit supports by default, JPEG (Joint Photographic Experts Group) are probably the most common. The JPEG format is optimized for photographs and similar continuous tone images that contain a large number of colors, and can achieve astonishing compression ratios, even while maintaining a high image quality. The JPEG compression technique analyzes images, removes data that is difficult for the human eye to distinguish, and stores the resulting data as a 24-bit color image [1].
