The counts of occurrences in each bin are then displayed on vertical axis.Ĭounts for each pixel intensity are normalized to range 0 to 255 before they are displayed on the graph. The tool then loops through every image pixel and counts the occurrence of each intensity. The number of bins is shown on the horizontal axis. This tool basically creates 256 bins for each color (red, green, blue) and greyscale (luma) intensity. How This Tool WorksĪn image histogram displays pixel value distribution within an image. It allows you to connect 2 Android devices through USB OTG and perform many of the tasks that are normally only accessible from a developer machine via ADB directly from your Android phone/tablet.
