Function Documentation

fromCvMat()

template<typename T >

yarp::sig::ImageOf< T > yarp::cv::fromCvMat

(

::cv::Mat &

cvImage

)

Convert a cv::Mat to a yarp::sig::ImageOf object.

Parameters

[in]

cvImage

cv::Mat input. Since the argument is passed as right-reference, the integrity of the data of the input cv::Mat is not guaranteed.

Note

The input cv::Mat's type(e.g. CV_8UC1) must be compatible with the output yarp image pixel type requested. E.g.:

• CV_8UC3 -> ImageOf<PixelRgb>/<PixelBgr>/<PixelHsv> OK
• CV_8UC1 -> ImageOf<PixelMono> OK
• CV_8UC3 -> ImageOf<PixelMono> NOT OK
• CV_8UC1 -> ImageOf<PixelRgb>/<PixelBgr>/<PixelHsv> NOT OK Please pay attention to the number of channels and pixel depth. Moreover pay attention on the lifetime of the memory of the input image, since no copy is involved.

Returns

the resulting yarp::sig::ImageOf.

toCvMat() [1/2]

cv::Mat yarp::cv::toCvMat

(

yarp::sig::Image &

yarpImage

)

Convert a yarp::sig::FlexImage to a cv::Mat object.

Parameters

[in]

yarpImage

yarp::sig::FlexImage input. Only VOCAB_PIXEL_RGB_INT, VOCAB_PIXEL_RGB, VOCAB_PIXEL_MONO_FLOAT are currently supported.

Returns

the resulting cv::Mat.

Examples

opencv/main.cpp.

Definition at line 84 of file Cv-inl.h.

toCvMat() [2/2]

template<typename T >

::cv::Mat yarp::cv::toCvMat

(

yarp::sig::ImageOf< T > &

yarpImage

)

Convert a yarp::sig::ImageOf to a cv::Mat object.

Parameters

[in]

yarpImage

yarp::sig::ImageOf input. Since the argument is passed as right-reference, the integrity of the data of the input yarp image is not guaranteed.

Note

The output cv::Mat has the default OpenCV color representation:

• 1 channel: GRAY
• 3 channels: BGR
• 4 channel: BGRA Moreover pay attention on the lifetime of the memory of the input image, since no copy is involved.

Returns

the resulting cv::Mat.
