Description

TheImage Complementblock computes the complement of a binary or intensity image.

For binary images, the block replaces pixel values equal to0with1and pixel values equal to1with0. In the output image, black and white are reversed. For intensity images, the block subtracts each pixel value from the maximum value that can be represented by the input data type and outputs the difference. In the output image, dark areas become lighter and light areas become darker.

For example, suppose the input pixel values are given byx(i) and the output pixel values are given byy(i). If the data type of the input is boolean, double or single, the block outputsy(i) = 1.0-x(i). If the input is an 8-bit unsigned integer, the block outputsy(i) = 255-x(i).

`Port_1`— Output image
matrix

The complement of the binary or intensity input image is returned as a matrix of intensity values. The size and data type of the output image are the same as those of the input image.
