Matched wavelets-their construction, and application to object detection

Wavelets matched to features in an image can be used to detect and/or classify objects. In this paper, image object features are generated by projecting the object at a finite number of angles. Wavelets matched to the projected object features in a training image are used to detect similar objects in test images. The detection is shown to be shift and scale insensitive and rotation insensitive to the number of discrete angles used for the projections.
