What is the pixel range for an RGB image?OrWhat is the minimum and maximum possible value for each of the pixels of an RGB image?
0 - 23
0 - 224
0 - 1
None of the above
Correct Answer :
D. None of the above
The RGB image has three different values for each color band, and the range of each color is 0 to 255. Hence, an RGB image is stored in a 3-dimensional array where each dimension represents one of the colors, with a value lying between 0 - 255.
