Questions tagged [binary-image]

Used for questions concerning images of two colors (usually black and white). Such images are common in object detection, edge detection, object counting etc.

A binary image is a digital image that has only two possible values for each pixel. Typically, the two colors used for a binary image are black and white, though any two colors can be used. The color used for the object(s) in the image is the foreground color while the rest of the image is the background color.
