The bit depth is the same but the top image is Note IM2UINT8 and the IM2UINT16 functions, are also useful when attempting to convert between different bit depths. Bit depth or color depth is only one aspect of color representation, 24-bit images can represent 16,777,216 colors, and 32-bit images in addition to having the same 16,777,216 colors in the RGB channels, also contain an additional channel, which is called alpha-channel. Simply import your image here and it'll get resized to the size you need. I understand the bit depth decides the quality and thereby the storage requirements for the image. how Learn more about image processing MATLAB. We can then say that the higher the image file's bit depth is, the better the quality of the image will be.
