How to convert RGB to HSV using OpenCV

Hey 

 I am sharing a simple program  which convert RGB image into HSV color space. I am handling cv::Mat instead of IplImage.

hsv.cpp

  /// HSV Conversion  
 #include "opencv2/highgui/highgui.hpp"   
 #include "opencv/cv.h"  
 #include <iostream>   
 #include <stdio.h>   
 using namespace std;   
 using namespace cv;   
  int main(int argc,   
   char *argv[]   
  )   
  {   
  /// input and hsv image variable  
  cv::Mat input,hsv;  
  input =imread(argv[1],1);  
  ///hsv conversion  
  cvtColor(input,hsv,CV_RGB2HSV);  
 ///displaying hsv and input  
  cv::imshow("hsv",hsv);  
  cv::imshow("input",input);  
  waitKey();   
  return 0;   
  }   



Output

OpenCV uses the BGR format, therefore try cvtColor(input,hsv, CV_BGR2HSV)

Lentin,

I am learning opencv and found your blog when looking for some examples of color space conversion. Thanks for your example. Btw, I think you don't need to include cv:: if you have the namespace line.

I have been suffering from (HERPES) disease for the last four years and had constant pain, especially in my knees. During the first year, I had faith in God that i would be healed someday.This disease started circulating all over my body and i have been taking treatment from my doctor, few weeks ago i was searching on the internet if i could get any information concerning the prevention of this disease, on my search i saw a testimony of someone who has been healed from GENITAL HERPES VIRUS by this Man DR.OZIGAN and she also gave the email address of this man and advise we should contact him for any sickness that he would be of help, so i wrote to DR.OZIGAN telling him about my (HERPES VIRUS) he told me not to worry that i was going to be cured!! hmm i never believed it,, well after all the procedures and remedy given to me by this man few weeks later i started experiencing changes all over me as the DR.OZIGAN assured me that i have cured, after some time i went to my doctor to confirmed if i have be finally healed behold it was TRUE So friends my advise is if you have such sickness or any other at all you can email DR.OZIGAN DR.OZIGANSPIRITUALHOME@GMAIL.COM OR DR.OZIGANSPIRITUALHOME@HOTMAIL.COM i am indeed grateful for the help, i will forever recommend you to my friends!!!
