Which one is robust to detect weak edges while going unresponsive to noise? Sobel or Canny edge detectors?
Best Answer
I would recommend you to try out all and see which one works better in your case. I had to do it once and I applied edge enhancement algorithms before using edge detection. In the following paperhttp://staff.science.uva.nl/~rein/nldiffusionweb/ named nldiffusioncode.pdf you can read about three algorithms they developed. The code is free and the link is matlab.zip. I could not find the actual webpage.
I also usedadapthisteq function from matlab to enhance contrast before before edge enhancement and detection
I don't know FDAtool. Typically image filters are performed using conv2(), imfilter(), edge(), stdfilt(), entropyfilt(), imtophat(), etc., or they are made with a custom function that you write.
