Location and Recognition of Flashlight Projections for Visual Interfaces
We consider the location and recognition of flashlight projections given the image sequence supplied by a fixed camera monitoring a physical surface. A quotient method extracts a ...

High Frequency Component Compensation based Super-Resolution Algorithm for Face Video Enhancement
This paper proposes a video-based super-resolution algorithm by high-frequency component compensation. Normalized logarithm distance (NLD) minimization on local shape feature is p...

A Note on Principal Point Estimability
We provide elementary geometric arguments to show that the principal point of cameras with small to moderate field of view cannot be reliably estimated from natural, noisy images ...

Model-Based Parameter Recovery from Uncalibrated Optical Images
We propose a novel method for quantitative interpretation of uncalibrated optical images which is derived explicitly from an analysis of the image formation model. Parameters chara...

Error bounds for correlation clustering
This paper presents a learning theoretical analysis of correlation clustering (Bansal et al., 2002). In particular, we give bounds on the error with which correlation clustering r...
