Detailed Description

Interface for generating per-pixel features for a drwnSegImageInstance object.

Derived classes can be used for generating different features, e.g., filterbank responses, HOG, etc. Typical usage is:

f.cacheInstanceData(instance);
f.appendAllPixelFeatures(phi);
f.clearInstanceData();
