    <p>I am trying to do the examples in the OpenCV book and I got to the part regarding cvCanny. I am trying to use it, but I keep getting a memory exception error of </p> <p><code>Unhandled exception at 0x75d8b760 in Image_Transform.exe: Microsoft C++ exception: cv::Exception at memory location 0x0011e7a4..</code></p> <p>I have also looked at another post that was similar to this question, but it did not help for me as I got the same error each time. Any help is greatly appreciated and the source code for the function is located below.</p> <pre><code>void example2_4(IplImage* img) { // Create windows to show input and ouput images cvNamedWindow("Example 2-4 IN", CV_WINDOW_AUTOSIZE); cvNamedWindow("Example 2-4 OUT", CV_WINDOW_AUTOSIZE); // Display out input image cvShowImage("Example 2-4 IN", img); // Create an image to hold our modified input image IplImage* out = cvCreateImage(cvGetSize(img), IPL_DEPTH_8U, 3); // Do some smoothing //cvSmooth(img, out, CV_GAUSSIAN, 3, 3); // Do some Edge detection cvCanny(img, out, 10, 20, 3); // Show the results cvShowImage("Example 2-4 OUT", out); // Release the memory used by the transformed image cvReleaseImage(&amp;out); // Wait for user to hit a key then clean up the windows cvWaitKey(0); cvDestroyWindow("Example 2-4 IN"); cvDestroyWindow("Example 2-4 OUT"); } int main() { // Load in an image IplImage* img = cvLoadImage("images/00000038.jpg"); // Run the transform example2_4(img); // clean the image from memory cvReleaseImage(&amp;img); return 0; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
