Description

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

Ports

Input

Port_1 — Input signal

Simulink.ImageType

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

Data Types: Simulink.ImageType

Output

Port_1 — Output signal

matrix

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

Output dimensions — Dimensions of block output signal

[480 640 3] (default)

Specify the dimensions of the output image signal. The expression must be a three-element numeric row vector of form: [Rows Columns Channels].

Programmatic Use
