Detecting Multiple Texture Planes using Local Spectral Distortion
This paper presents a spectral method for identifying multiple texture planes. We commence by showing how pairs of spectral peaks can be used to make direct estimates of the slant and tilt angles. Our method commences by computing the a ne distortion matrices for pairs of corresponding spectral peaks. We show that the directions of the eigenvectors of the a ne distortion matrices can be used to...
متن کاملImproved Orientation Estimation for Texture Planes Using Multiple Vanishing Points
Vanishing point locations play a critical role in determining the perspective orientation of textured planes. However, if only a single vanishing point is available then the problem is undetermined. The tilt direction must be computed using supplementary information such as the texture gradient. In this paper we describe a method for multiple vanishing point and, hence complete perspective pose...
متن کاملAccumulating Spectral Evidence for Perspective Views of Texture Planes
Multiple vanishing point detection provides the key to recovering the perspective pose of textured planes. If vanishing points are to be detected from spectral information then there are two computational problems that need to be solved. Firstly, the search of the extended image plane is unbounded, and hence the location of vanishing points at or near in nity is di cult. Secondly, correspondenc...
متن کاملTexture segmentation and analysis using local spectral methods
In this paper we present two new methods for texture segmentation and analysis using local spectral methods. The first approach to the problem is to use a modular pattern detection in textured images based on the use of a PseudoWigner Distribution (PWD) followed by a decorrelation procedure that consists of a principal component analyzer (for texture segmentation). The goal is to combine the ad...
متن کاملEstimating the perspective pose of texture planes using spectral analysis on the unit sphere
Multiple vanishing point detection provides the key to recovering the perspective pose of textured planes. If vanishing points are to be detected from spectral information then there are two computational problems that need to be solved. Firstly, the search of the extended image plane is unbounded, and hence the location of vanishing points at or near in/nity is di0cult. Secondly, correspondenc...
