try to find:

Paula, I. C., Medeiros, F. N. S., Bezerra, F. N., & Ushizima, D. M. (2012). Multiscale Corner Detection in Planar Shapes. Journal of Mathematical Imaging and Vision, 45(3), 251–263. doi:10.1007/s10851-012-0365-8

the evaluation tests such as accuracy, repeatability can use to measure the performance.

Seyed Mostafa Mousavi Kahaki

Corner detection methods can divided into three main categories, intensity based, model based and edge based. based on your question you need to follow model based approaches.

Lambert Zijp

Could you post an example image?

George Azzopardi

You may have a look at the COSFIRE approach

Thanks to all for this helpfull discussion.

Sir Seyed mostafa, i m interested by corner detection in intensity based and model based (V-, T-, X-).

Sir George, I used FAST corner detection and I had very good results to detect corner, but I need some information on each corner detected, as angle, orientation...

Best regards

If you need these information you can achieve using ARCSS merhod. i am developing one but still under progress. while it finish i will broadcast also. in the meantime you can use CSS based approaches. the angle of the corners are not available in intensity based approaches.

Dear S.M.M. KAHAKI, I need paper who talk about ARCSS and CSS please.

we have the same goal, I also work on a method that is in the process of validation and test, and I'm looking for recent work related.

I'm waiting for you results and your recent paper

Best Regards

Mohammad Esmaeilpour

One of the well-known method for detecting the corner is Phase Congruence (PC), It would be very helpful. I can give you MATLAB based code for this task, notify me if you want.
