Load a image and save that image in many color changers using javaCV

Today I will show you load a image and save that image in many color changers.

1. Make a new java project and import the Open CV libraries
2. If you don't know about it please follow the first post with javaCV

3.  IplImage image =cvLoadImage("img.JPG");

Make IplImage type variable it name is "image". "img.JPG" is assigned to to image.

4. IplImage hsv=cvCreateImage(cvGetSize(image),IPL_DEPTH_8U,3);

• make a HSV type image
• cvcreateImage() need 3 parameters.
1. size of image
2. Type of image
3. Nomber of frames in the image.
• if it is 1 ,it is gray color image
• if it is 3,it is colored image. 3 frames mean it have BGR(Blue,green,Red) frames.
• if it is 4,it contain four frames. That mean it have BGR frames and alpha frame. Alpha is transparancy of image

5. IplImage gray=cvCreateImage(cvGetSize(image),IPL_DEPTH_8U,1);

make a gray colored image

cvCvtColor(image,hsv,CV_BGR2HSV);

Convert original image to a HSV image

cvCvtColor(image, gray, CV_BGR2GRAY);

convert original image to gray image

cvShowImage("Original",image);

Make a window to show original image. Window name is "original"

cvShowImage("HSV", hsv);

Make a window to show HSV image. Window name is "HSV"

cvShowImage("Gray", gray);

Make a window to show Gray image. Window name is "Gray".

        cvWaitKey();
        
        cvSaveImage("HSV.JPG",hsv);

Save the hsv image in jpg type. It name will be "HSV.JPG"

cvSaveImage("Gray.JPG",gray);

Save the gray image in jpg type. It name will be "Gray.PGP"

   
        cvReleaseImage(image);
        cvReleaseImage(hsv);
        cvReleaseImage(gray);

Release the memory allocated for image,hsv,gray variable we made.

 
Type above codes. Then go to project folde and paste a image to src folde.

Then go to your project folde. You can see that saved images.
