G. Deng, "A robust algorithm for feature detection with application to speed limit sign detection," submitted to Image and Vision Computing, April, 2008.

-Here is the test image set. It is a big file containing more than 100 traffic sign images (color, 480x640).

-To find out how to use the software to reproduce the results, you may want to read the README first.

-You may want to see the detection results in avi format: detection results (compressed video) (~4.7MB, may not display properly for certain versions of windows media player) and detection results (uncompressed video) (~110MB).
