Matrix To Image
Libraries:
Computer Vision Toolbox OpenCV Interface for Simulink
Description
The Matrix To Image block converts matrix data to Simulink® image data.
Examples
Ports
Input
Port_1 — Input signal
matrix
Input signal to the Matrix To Image block. The input is a numerical matrix.
Data Types: uint8
| uint16
| int8
| int16
| single
| double
Output
Port_1 — Output signal
Simulink.ImageType
Output signal from the Matrix To Image block. The output is an
image in Simulink.ImageType
data type.
Data Types: Simulink.ImageType
Parameters
Rows — Number of rows in image data
'480'
(default) | positive integer
Specify the number of rows in the image data as a positive integer.
Programmatic Use
Block Parameter:

double |
Value: positive integer |
Default:
'480'
|
Columns — Number of columns in image data
'640'
(default) | positive integer
Specify the number of columns in the image data as a positive integer.
Programmatic Use
Block Parameter:

|
Channels — Number of color channels or samples for each pixel in the array
3
(default) | 1
Specify the number of color channels or samples for each pixel in the array as
1
or 3
. The number of channels must correspond
to the number of color channels in the color format of the image data. These are the
values of Channels for the supported color formats:
Channels | Color Format |
---|---|
1 | Grayscale |
3 | RGB |
3 | BGR |
Programmatic Use
Block Parameter:

Block Parameter:
Layout |
Type: character vector |
Value:
'Column-major' | 'Row-major' |
Default:
'Column-major'
|
Color Format — Color format of pixels in underlying image data
'RGB'
(default) | 'Grayscale'

as Grayscale
, RGB
, or
BGR
.
Programmatic Use
Block Parameter:
ColorFormat |
Type: character vector |
Value:
'Grayscale' | 'RGB' |
