C++ (Cpp) ImageParam::set Examples

Example #1

File: NamedWindow.cpp Project: yongyi781/halide-magnify

void NamedWindow::showImage3D(Halide::Image<float> im)
{
	static Halide::Func convert("convertToMat3D");
	static Halide::ImageParam ip(Halide::Float(32), 3);
	static Halide::Var x, y, c;

	if (!convert.defined())
	{
		convert(c, x, y) = Halide::cast<uint8_t>(ip(x, y, 2 - c) * 255);
		convert.vectorize(x, 4).parallel(y, 4);
	}

	ip.set(im);
	cv::Mat mat(im.height(), im.width(), CV_8UC3, cv::Scalar(0));
	convert.realize(Halide::Buffer(Halide::UInt(8), im.channels(), im.width(), im.height(), 0, mat.data));
	cv::imshow(name, mat);
}

Example #2

File: NamedWindow.cpp Project: yongyi781/halide-magnify

void NamedWindow::showImage2D(Halide::Image<uint8_t> im)
{
	static Halide::Func convert("convertToMat2D");
	static Halide::ImageParam ip(Halide::UInt(8), 2);
	static Halide::Var x, y;

	if (!convert.defined())
	{
		convert(x, y) = ip(x, y);
		convert.vectorize(x, 4).parallel(y, 4);
	}

	ip.set(im);
	cv::Mat mat(im.height(), im.width(), CV_8UC1, cv::Scalar(0));
	convert.realize(Halide::Buffer(Halide::UInt(8), im.width(), im.height(), 0, 0, mat.data));
	cv::imshow(name, mat);
}

Example #3

File: Param.cpp Project: bleibig/Halide

    param.set(im);
}
