wangzhengyang 718c41634f feat: 切换后端至PaddleOCR-NCNN，切换工程为CMake 
1.项目后端整体迁移至PaddleOCR-NCNN算法，已通过基本的兼容性测试
2.工程改为使用CMake组织，后续为了更好地兼容第三方库，不再提供QMake工程
3.重整权利声明文件，重整代码工程，确保最小化侵权风险

Log: 切换后端至PaddleOCR-NCNN，切换工程为CMake

OpenCV.js Performance Test

Node.js Version

Prerequisites

  1. node.js, npm: Make sure you have installed these beforehand with the system package manager.

  2. Benchmark.js: Make sure you have installed Benchmark.js by npm before use. Please run npm install in the directory <build_dir>/bin/perf.

How to Use

For example, if you want to test the performance of cvtColor, please run perf_cvtcolor.js by node in terminal:

node perf_cvtcolor.js

All tests of cvtColor will be run by above command.

If you just want to run one specific case, please use --test_param_filter="()" flag, like:

node perf_cvtcolor.js --test_param_filter="(1920x1080, COLOR_BGR2GRAY)"

Browser Version

How to Use

To run performance tests, please launch a local web server in <build_dir>/bin folder. For example, node http-server which serves on localhost:8080.

Navigate the web browser to the kernel page you want to test, like http://localhost:8080/perf/imgproc/cvtcolor.html.

You can input the parameter, and then click the Run button to run the specific case, or it will run all the cases.
