matplot-opencv

This library offers the data of OpenCV's cv::Mat a quick review as showing line, histogram, 1D curve, or 2D curve for algorithm development, with just simple few lines of code. Also, this library takes the advantage of the most popular matplotlib as the core of drawing, and enjoys its beautiful displays.

• Please report bugs to Issues

System requirements:

• Python > 3.0
• OpenCV > 2.0
• numpy
• matplotlib

Installation:

1. Install this library with:
   python setup.py install
2. Involve the resources in /include into your project.

ps. Currently only Visual Studio 2010 with python 3.4 is tested.

Usage and sample code:

Three functions are shown below:

• Draw a 2D filter

#include <opencv2/imgproc/imgproc.hpp>
#include <matplot-opencv.hpp>
using namespace cv;
namespace plt = matplotcv;
void main(){
    Mat	mat = (Mat_<float>(3,3)<<1,2,1,2,4,2,1,2,1);
    plt::plot_surface(mat);
}

Result:

• Draw a histogram

#include <opencv2/imgproc/imgproc.hpp>
#include <matplot-opencv.hpp>
using namespace cv;
namespace plt = matplotcv;
void main(){
    Mat seq = (Mat_<float>(1,4)<<1,2,3,2);
    plt::hist(seq,3);
}

Result:

• Draw a 1D curve

#include <opencv2/imgproc/imgproc.hpp>
#include <matplot-opencv.hpp>
using namespace cv;
namespace plt = matplotcv;
void main(){
    Mat seq = (Mat_<float>(1,4)<<1,4,2,5);
    plt::curve(seq);
}

Result:
