Object detection through matched wavelet transforms

The paper provides a closed form solution to least squares matching of the energy spectrum density of an orthonormal MRA-generating wavelet with that of a specified arbitrary signal. The authors had previously proposed algorithms for matching with samples of energy spectrum densities. An approach is also proposed to use matched wavelets in detecting an object in an image. Furthermore, the approach captures size, orientation and position information.
