As many you asked, what does an image histogram show? Histogram Approach An image histogram is a gray-scale value distribution showing the frequency of occurrence of each gray-level value. For an image size of 1024 × 1024 × 8 bits, the abscissa ranges from 0 to 255; the total number of pixels is equal to 1024 × 1024.If you want to know how many times an event occurred within a specific range, simply look at the top of the bar and read the value on the y-axis at that point. For example, looking at the histogram, the number of players in the range of 6’0” to just under 6’2” is 50.
