A Factorization Based Self-Calibration for Radially Symmetric Cameras
The paper proposes a novel approach for planar selfcalibration of radially symmetric cameras. We model these camera images using notions of distortion center and concentric distor...

Movie summarization based on audiovisual saliency detection
Based on perceptual and computational attention modeling studies, we formulate measures of saliency for an audiovisual stream. Audio saliency is captured by signal modulations and...

Directed acyclic graph based mode optimization for H.263 video encoding
Optimal mode selection for video coding is important in minimizing visual distortion given a rate constraint, and it has been studied in the literature using a single previous mac...

Color Spectrum Normalization: Saliency Detection Based on Energy Re-allocation
Spectrum normalization is a process shared by two saliency detection methods, Spectral Residual (SR) and Phase Fourier Transform (PFT). In this paper, we point out that the essence...
