3-D Planar Orientation from Texture: Estimating Vanishing Point from Local Spectral Analysis
This paper describes a novel method for recovering the perspective geometry of textured surfaces from local spectral moments. It commences by computing the Fourier power spectrum at each of a series of local neighbourhoods. We illustrate how the vanishing point of the global perspective geometry can be estimated from local spectral moments. This is a two-step process. We commence by identifying...

This paper describes a new method for recovering the perspective geometry of textured planes from local spectral analysis. The novel contribution of the work is to use the angular distribution of texture moments to locate the vanishing point of textured planes viewed under perspective geometry. Our key observation is that lines of uniform spectral orientation radiate from the vanishing point. W...
متن کاملA Scale Adaptive Method for Estimating the Perspective Pose 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 infinity is difficult. Secondly, correspond...
متن کاملDevelopment of an Index-based Regression Model for Soil Moisture Estimation Using MODIS Imageries by Considering Soil Texture Effects
Soil moisture content (SMC) is one of the most significant variables in drought assessment and climate change. Near-real time and accurate monitoring of this quantity by means of remote sensing (RS) is a useful strategy at regional scales. So far, various methods for the SMC estimation using a RS data have been developed. The use of spectral information based on a small range of electromagnetic...
