halide图像处理加速库Windows环境配置以及与opencv间数据转换

一、下载Halide：Releases · halide/Halide (github.com)

选择windows版本

二、创建cmake文件

set(Halide_DIR "xxx/Halide-17.0.2-x86-64-windows/lib/cmake/Halide")
find_package(Halide REQUIRED)
set(OpenCV_DIR "xxx/opencv/build")
find_package(OpenCV REQUIRED)
include_directories("xxx/Halide-17.0.2-x86-64-windows/include")
 target_link_libraries(test_mipp ${OpenCV_LIBS}  "xxx/Halide-17.0.2-x86-64-windows/lib/Release/Halide.lib")

显示缺少zlib，png等库，不用管，这个是用来加载图像的，我们用opencv，不需要这些库

三、测试样例程序

cv::Mat cv_image = cv::imread("xxx.jpg", cv::ImreadModes::IMREAD_GRAYSCALE);
 
	Halide::Buffer<uint8_t> input(
		cv_image.data,                                  // 数据指针
		cv_image.cols, cv_image.rows, cv_image.channe
