I Want to Write a Face Detection Program Using C++ Where Should I Start and What Should I do

          Without any doubt, all of us can write the research program using C++ based on face detection. To make that process ease our research experts have offered this article. Let’s start this article with the creation of program.

Start and Create C++ Program

         Initially, we have to use the visual studio to create the standard C++ programs through the below mentioned steps.

• We have to create a new project from File –> New Project and add the new file to the project and add C++ code
• Following that, we have to compile and run the program using visual studio

Face Detection Program Using C++

         For instance, we have heighted the sample code based on C++ for the process which are highlighted below,

• To include required header files from OpenCV directory

#include “/usr/local/include/opencv2/objdetect.hpp”

#include “/usr/local/include/opencv2/highgui.hpp”

#include “/usr/local/include/opencv2/imgproc.hpp”

#include <iostream>

using namespace std;

using namespace cv;

• To colour conversion and re-size the images

cvtColor( img, gray, COLOR_BGR2GRAY );

ouble fx = 1 / scale;

resize( gray, smallImg, Size(), fx, fx, INTER_LINEAR );

equalizeHist( smallImg, smallImg );

• To detect faces of different sizes using cascade classifier

cascade.detectMultiScale( smallImg, faces, 1.1, 2, 0|CASCADE_SCALE_IMAGE, Size(30, 30) );

       Most significantly, our research experts are upgrading themselves by in depth knowledge through the topic. Join us to get delightful work in your face detection research.
