Computer Vision Toolbox Interface for OpenCV in Simulink

Description

TheToOpenCVblock converts the Simulink^®data types to Simulink OpenCV data types.

Ports

Inputs

expand all

`Port_1`— Input signal
scalar | vector | matrix | simulink bus | simulink image

Input signal to theToOpenCVblock. The input can be of different data types. Each of the input data types determines the output data type of the block.

Output

expand all

`Port_1`— Output signal
scalar | vector | matrix | simulink bus | simulink image

Output signal from theToOpenCVblock. The output signal supports OpenCV types. For more information, seeMapping Input and Output Data Types.

Data Types:OpenCV types

Parameters

expand all

`DataType`— Data type of the Input signal of ToOpenCV block
`input data type`(default)

Specifies the input data type of theToOpenCVblock. Thetablelists the one-to-one mapping of the input versus output data types of theToOpenCVblock.

Programmatic Use

Block Parameter:DataType

Type:character vector

Value:input data type

Default:'Point2i'

Model Examples

Smile Detection by Using OpenCV Code in Simulink

Build a smile detector by using theOpenCV Importerapp. The detector estimates the intensity of the smile on a face image or a video. Based on the estimated intensity, the detector identifies an appropriate emoji from its database, and then places the emoji on the smiling face.

Convert RGB Image to Grayscale Image by Using OpenCV Importer

Convert an RGB image to a grayscale image by using theOpenCV Importerapp. The converter converts an RGB image to a grayscale image by eliminating the hue and saturation information while retaining the luminance.

Draw Different Shapes by Using OpenCV Code in Simulink

Draw different shapes on images by usingOpenCV Importer.
