We determined the overall disparity from stereo images using multiscale products of disparity values. Using the wavelet transform, we used a multiresolution analysis to calculate disparity values from stereo images at different scales. Forming the product of disparities and rescaling resulted in a disparity map that was directly related to depth. Using a multiresolution approach allowed us to more accurately determine disparity by examining the consistency of results through different scales. Using this approach could form the basis of an effective method for depth estimation.
