Image Processing Toolbox

isbw

Return true for a binary image

Syntax

flag = isbw(A)

Description

flag = isbw(A) returns 1 if A is a binary image and 0 otherwise.

isbw uses these criteria to decide if A is a binary image:

• If A is of class double, all values must be either 0 or 1, the logical flag must be on, and the number of dimensions of A must be 2.
• If A is of class uint8, the logical flag must be on, and the number of dimensions of A must be 2.
• If A is of class uint16, it is not a binary image. (The toolbox does not support uint16 binary images.)

Note    A four-dimensional array that contains multiple binary images returns 0, not 1.

Class Support

A can be of class uint8, uint16, or double.
