Description

The From Simulink Image block converts Simulink® image data to matrix data.

Examples

Track Marker Using Simulink Images

Track Marker Using Simulink Images

Track a marker on a whiteboard by using images of the Simulink.ImageType data type.

Ports

Input

expand all

Input signal to the From Simulink Image block. The input is a Simulink image data type.

Data Types: Simulink.ImageType

Output

expand all

Output signal from the From Simulink Image block. The output is a matrix or an array, depending on the format of the input.

  • M-by-N matrix — The input is a Grayscale image. M and N are the height and width of the image, in pixels.

  • M-by-N-by-C matrix — The input is an RGB or BGR image. M and N are the height and width of the image, in pixels. C is the number of color channels.

Data Types: integer | single | double | Boolean

Parameters
