Im trying to understand goodFeaturesToTrack and in the documention at this link:

http://docs.opencv.org/modules/imgproc/doc/feature_detection.html?highlight=goodf#goodfeaturestotrack

it says "

Note

If the function is called with different values A and B of the parameter qualityLevel , and A > {B}, the vector of returned corners with qualityLevel=A will be the prefix of the output vector with qualityLevel=B . "

is A > {B} just a is greater than b or does it mean something else

It is a function that defines a map of cornerness response!

As feature, gradient information is frequently used. This function defines how descriminate this pixel location is for the scene/object. You should read through the paper discussing it:

J. Shi and C. Tomasi. Good Features to Track. Proceedings of the IEEE Conference on Computer Vision and Pattern Recognition, pages 593-600, June 1994.
