Edge detection is a very time consuming process. The objective of this project is to compare and figure out best domain ( frequency domain or spatial domain) for fast edge detection, and also to determine best method (sobel or difference of gaussian) for fast edge detection.
The project is written in Matlab. Test results are presented in brief below, when run on an image of size 512X512.
Elapsed time for DOG in Frequency domain - 0.150253 seconds
Elapsed time for DOG in Spatial domain - 0.045588 seconds
