OpenCVGUI
Do you like OpenCV Highui but it's not enough and don't want waste your time in a new UI SDK? This is your solution! OpenCVGUI is a new graphical user inteface for OpenCV with different widgets and tools to provide developers a new and more powerful user interface with 3D and 2D plotting support, advanced forms, with small dependencies and OpenGL based.
Why OpenCVGUI: more Powerful and exactly so simple than OpenCV Highui.
Dependencies
- GLEW
- xorg-dev
Build
- git submodule update --init --recursive
- mkdir build
- cd build
- cmake ..
- make
- sudo make install
Features
- No complex sdk framework like others.
- It's like OpenCV Highui calls, simple and clean.
- Computer vision in different Thread than UI
- Image render
- Forms
- Input Text
- Buttons
- Radio buttons
- Checkboxs
- Sliders and progress bars
- File Management (in progress)
- 2D plot
- 2D multiplot
- 3D Plot
Short snippets
Init the GUI
OpenCVGUI::init();Create a new window
OGUICVWindow* window= OpenCVGUI::namedWindow("Wellcome to OpenCVGUI Example 2");Show image in window
Mat image= imread("./lena.jpg");
window->imshow("image title key like highui imshow", &image);Basic Example
#include "OGUI.h"
#include "OGUISlider.h"
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
using namespace OpenCVGUI;
using namespace cv;
VideoCapture cap;
Mat frame, gray;
double thr=125;
OGUICVWindow *window;
void cv_process() {
while(app_is_running) {
cap >> frame;
window->imshow("camera", &frame);
Mat output;
cvtColor( frame, gray, COLOR_RGB2GRAY );
threshold( gray, output, (int)thr, 255, CV_THRESH_BINARY);
window->imshow("threshold", &output);
}
}
void on_change_slider_threshold(double value){
thr= value;
}
int main( int argc, const char* argv[] )
{
// Init GUI
OpenCVGUI::init();
// Create our window
window= OpenCVGUI::namedWindow("Wellcome to OpenCVGUI Example 2");
// Create the Forms we need and add to window
OGUISlider slider("Threshold", 0, 255, 125);
slider.setCallBack(on_change_slider_threshold);
window->addFormWidget(&slider);
// Start video capture
cap.open(0);
if(cap.isOpened()){
cap >> frame;
// show image
window->imshow("camera", &frame);
}else{
return 0;
}
// Convert frame, threshodl and show
cvtColor( frame, gray, COLOR_RGB2GRAY );
Mat output;
threshold( gray, output, 125, 255, CV_THRESH_BINARY);
window->imshow("threshold", &output);
// Start the Comptuer vision process
OpenCVGUI::app_run(cv_process);
