Straight Lines and Circles in the Log-Polar Image
Foveal or spatially-variant image representations are important components of active vision systems. Log-polar sampling is a particularly powerful example as a result of the simpl...

Video Shot Cut Detection using Adaptive Thresholding
The performance of shot detection methods in video sequences can be improved by the use of a threshold that adapts itself to the sequence statistics. In this paper we present some...

Gaze Determination via Images of Irises
In this paper, we present a new approach for measuring eye-gaze of human via images of the irises. Two iris contours are approximately modeled as two circles having known radii an...

Integrated Segmentation and Depth Ordering
We describe a method to segment and depth order motion layers simultaneously in an image sequence. Previous approaches have tended to ignore the depth ordering issue or treat it a...

Morphological Change Detection Algorithms for Surveillance Applications
Vision-based systems for remote surveillance usually involve change detection algorithms for intruders, obstacles or irregularities detection. In particular, there is a potentiall...

Probabilistic PCA and ICA Subspace Mixture Models for Image Segmentation
High-dimensional data, such as images represented as points in the space spanned by their pixel values, can often be described in a significantly smaller number of dimensions than...

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...

Resolving Visual Uncertainty and Occlusion through Probabilistic Reasoning
Tracking interacting human body parts from a single two-dimensional view is difficult due to occlusion, ambiguity and spatio-temporal discontinuities. We present a Bayesian networ...

A Comparative Study on Disparity Analysis Based on Convergent and Rectified Views
In this paper, we present results of a comparative study on disparity analysis of convergent stereo systems. If the epipolar geometry is known, disparity analysis can be performed...

Quantifying Ambiguities in Inferring Vector-Based 3D Models
This paper presents a framework for directly addressing issues arising from self-occlusions and ambiguities due to the lack of depth information in vector-based representations. V...
