Detailed Description
SIFT classifier.This class provides a classifier that uses OpenCV to detect objects in a given image by matching features using SIFT. The objects are reported back as regions of interest. Each ROI contains an object.
This code is based on the sift package provided by Rob Hess. at http://web.engr.oregonstate.edu/~hess/

Classify image.
The current buffer is processed and scanned for the features the classifier has been written and initialized for. It returns a list of disjunct regions of interest.
- Returns:
- disjunct list of extracted regions of interest
