Detailed Description

Convert image types.

The following example available in tutorial-image-converter.cpp shows how to convert an OpenCV cv::Mat image into a vpImage:

#include <visp/vpImageIo.h>
#include <visp/vpImageConvert.h>
int main()
{
#if defined(VISP_HAVE_OPENCV) && (VISP_HAVE_OPENCV_VERSION >= 0x020100)
  cv::Mat A;
  A = cv::imread("lena.bmp", CV_LOAD_IMAGE_GRAYSCALE);
  vpImage<unsigned char> I;
  vpImageConvert::convert(A, I);
#  ifdef VISP_HAVE_LIBPNG
  vpImageIo::write(I, "lena.png"); // Gray
#  endif
#endif
}

Convert a yarp::sig::ImageOf<yarp::sig::PixelRgba> to a vpImage<vpRGBa>

A yarp::sig::Image is a YARP image class. See http://eris.liralab.it/yarpdoc/df/d15/classyarp_1_1sig_1_1Image.html for the YARP image class documentation.

Parameters

src	: Source image in YARP format.
dest	: Destination image in ViSP format.
copyData	: Set to true to copy all the image content. If false we only update the image pointer.

v	V component of a pixel.
r	Red component from the YUV coding format. This value is computed using: $r = 0.9999695y - 0.0009508(u-128) + 1.1359061*(v-128)$
g	Green component from the YUV coding format. This value is computed using: $g = 0.9999695y - 0.3959609(u-128) - 0.5782955*(v-128)$
b	Blue component from the YUV coding format. This value is computed using: $b = 0.9999695y + 2.04112(u-128) - 0.0016314*(v-128)$
