Edge detection (also called “boundary detection”) is a fundamental problem in image processing. The ability to accurately detect visible “edges” in an image has many applications – ranging from missile targeting to OCR to cool Photoshop effects. In this project I’ve compiled 6 well-known edge detection algorithms (along with two of my own).
For those who have never used edge detection algorithms before, here are examples of various outputs:

Unfortunately, some virus scanners will flag these .zip files as suspicious simply because they contain source code and/or executable files. I have submitted my projects to a number of companies in an attempt to rectify these false-positives. Some have been cooperative. Others have not. If your virus scanner alerts you regarding these files, please allow the file to be submitted for further analysis (if your program allows for that). This should help ensure that any false-positive warnings gradually disappear for all users.
