goodfeaturestotrack

[asda333]

Hey guys

Does anyone have experience with goodfeaturestotrack. I am using it to detect corners and i have printed a sheet with an L shape on a green background and the program only detects the corner of border (when you print you have a white border) it detects that corner instead of the L corner.

Here is an example

my code i use for goodfeatures to track is 0.1 distance and 5000 quality level any lower it will start detecting corners that are not there.

Regards
