Abstract

The phase-coded image of a scene results from the projection of a grid on the objects of the scene. We show how the wavelet transform can be used as an oriented pattern detector for the segmentation of phase-coded images. The detector coupled with a rotation of the digital camera enables detection of 3D planar surfaces. A digital image rotation technique using a scaling function from multiresolution analysis is also presented. Discussion of Fourier transform methods of segmentation of phase-coded images motivates the oriented pattern detection approach.
