In this paper we present a new method to perform reliable
images classification. We have introduced a novel interest
point selection after SIFT evaluation criteria. We have
presented an algorithm for interest point detection that is
invariant to important scale changes. A comparison with
existing method shows that our interest point on SIFT
method bring fast and accurate results. Future work we can
extracts special structural features that can be concatenated
with this method to meet specific cases for full recognition.
