Check if image is correct (corrupted) javaCV

I have a list of directories and subdirectories with images. I am using JavaCV to read all images and using cvShowImage to display those images. I am reading files using the listFilesForFolder function. My problem is that some of the images in these folders are invalid (corrupted). So I am getting Opencv exception errors:

OpenCV Error: Null pointer () in cvReleaseImage, file ..\..\..\..\opencv\modules\core\src\array.cpp, line 2983
Exception in thread "main" java.lang.RuntimeException: ..\..\..\..\opencv\modules\core\src\array.cpp:2983: error: (-27)  in function cvReleaseImage
at org.bytedeco.javacpp.opencv_core.cvReleaseImage(Native Method)

      

        
        
        
      

    

How can I check my code if the image is indeed (corrupted) or not to continue with the for loop in which I was reading all my images? I use the following function to read images:

public IplImage openImage(String name) {


    IplImage img = cvLoadImage(name);
    cvShowImage("hello", img);
    cvWaitKey();
    cvReleaseImage(img);
    return img;
}

      

        
        
        
      

    

When I run the program, I am having problems on the cvReleaseImage (img) line.
