WebJul 13, 2024 · 16-bit integer numbers range between 0 and 65535 (= 2 16 −1). They need to be coerced to the 8-bit range: 0 to 255 (= 2 8 −1). So divide by 256 (= 2 8 ): image = image / 256. This will yield an array of floating-point pixel values. Its data type must be explicitly cast to 8-bit integer in order to drop any fractions. WebAn image whose data matrix has class uint8 is called an 8-bit image; an image whose data matrix has class uint16 is called a 16-bit image. The image function can display 8- or 16-bit images directly without converting them to double precision. However, image interprets matrix values slightly differently when the image matrix is uint8 or uint16 . crypto news yesterday
