Fast GEM wavelet-based image deconvolution algorithm
The paper proposes a new wavelet-based Bayesian approach to image deconvolution, under the space-invariant blur and additive white Gaussian noise assumptions. Image deconvolution ...

Jumping snakes and parametric model for lip segmentation
Lip segmentation is an essential stage in many multimedia systems such as videoconferencing, lip reading, or low bit rate coding communication systems. In this paper, we propose a...

Contour detection operators based on surround inhibition
We propose a biologically motivated computational step, called non-classical receptive field (non-CRF) inhibition, to improve contour detection in images of natural scenes. We aug...

Graylevel alignment between two images using linear programming
A critical step in defect detection for semiconductorprocess is to align a test image against a reference. This includes both spatial alignment and grayscale alignment. For the la...
