Matching signs Using SURF
2 views (last 30 days)
I am trying to match signs of American Sign Language using SURF.
Ideally, it should match with "C" in database images but it is not so.
I am attaching code.
Currently, input image is CC.jpg
I have to make such a code that should work different input images like AA.jpg, BB.jpg, CC.jpg, DD.jpg and so on.

This is similar to the example Detecting Objects in a Cluttered Scene With Point Feature Matching.
First, make sure you are detecting enough features in both CC.jpg and database_labelled.jpg. You can detect more features using the "MetricThreshold" argument on detectSURFFeatures. Then, test different levels of the "MatchThreshold" argument on matchFeatures. Sometimes the default settings are not sufficient.
Also, is there enough resolution to database_labelled.jpg to detect at least 20+ features for each sign configuration? If not, this will significantly impair your ability to use features to recognize the sign.
Hope this helps,
