Stereo Disparity from Local Image Phase
نویسنده
چکیده
This report describes a stereo algorithm which uses estimates of local image phase to calculate a disparity map for stereo images. Phase diierence and local frequency are measured by ltering the stereo images with Gabor lters and their derivatives, and the results are used to calculate the local disparity. Due to the limitations on the possible scale of the measured disparity imposed by the use of local image phase, a coarse-tone strategy is implemented to extend the algorithm to any disparity scale. Results obtained with the algorithm are shown on random dot stereograms and artiicial images with known ground truths and on real images.

Stereoscopic ranging by matching image modulations
We apply an AM-FM surface albedo model to analyze the projection of surface patterns viewed through a binocular camera system. This is used to support the use of modulation-based stereo matching where local image phase is used to compute stereo disparities. The local image phase is an advantageous feature for image matching, since the problem of computing disparities reduces to identifying loca...

A stereo similarity function based on local multi-model monogenic image feature descriptors LMFD is proposed to match interest points and estimate disparity map for stereo images. Local multi-model monogenic image features include local orientation and instantaneous phase of the gray monogenic signal, local color phase of the color monogenic signal, and local mean colors in the multiscale color...

Estimating depth information from two-dimensional stereoscopic image pairs is an important task in image processing. The disparity, i.e. the displacement of corresponding pixels in the image pair, can be estimated directly from local image phase in the fourier domain. In this paper a combined FFTbased approach for disparity estimation is proposed, where additional magnitude information is inclu...
