A computer implemented method, apparatus, data processing system, and computer usable program code are provided for identifying interest points. A set of digital images and a set of threshold values are received, where the set of digital images includes a set of digital frames. A set of directional values are calculated for each of a set of pixels within each digital frame in the set of digital frames. A set of interest points are identified within each digital frame in the set of digital frames using the set of threshold values and the set of directional values. Finally, a set of characteristics is identified for the set of interest points.
