Book DescriptionCuda is a computing architecture designed to facilitate the development of parallel programs. in conjunction with a comprehensive software platform, the Cuda architecture enables programmers to draw on the immense power of graphics processing units (GPUs) when building high-performance applications. GPUs, of course, have long been available for demaning graphics and game applications. cuda n

First, the preface This paper mainly explains a small example of cuda parallel acceleration, and accelerates the nearest neighbor interpolation algorithm for image scaling. second, code implementation Because each new pixel is calculated in the same way as it is scaled, parallel computations can be used, as do the resize in OpenCV. main.cu////#include "cuda_runt

This is a wonderful idea ... We don't talk about whether it means anything. This wonderful idea appears based on the following 2 points: 1, OPENCV code once compiled into a library file, it is difficult to modify the internal code, although most of the need to modify the part has been referred to the interface above. 2, OpenCV in the use of Cuda accelerated

Syntax highlighting in addition to the look comfortable, you can use F11 to find functions, variable definitions, hitting the function will also have a corresponding hint.The following is a set of code highlighting.In the Helloworldcuda.cu file above, the Cuda C + + keyword __global__ and so on are not highlighted, and there is a stroke curve. The following syntax highlighting of
