Morphological grayscale reconstruction in image analysis: Applications and efficient algorithms
- IEEE Transactions on Image Processing
, 1993
"... Morphological reconstruction is part of a set of image operators often referred to as geodesic. In the binary case, reconstruction simply extracts the connected components of a binary image I (the mask) which are \marked " by a (binary) image J contained in I. This transformation can be ext ..."

at demonstrating the usefulness of this transformation for image ltering and segmentation tasks. Lastly, the paper focuses on implementation issues: the standard parallel and sequential approaches to reconstruction are brie y recalled; their common drawback is their ine ciency on conventional computers. To improve
Stochastic Tracking of 3D Human Figures Using 2D Image Motion
- In European Conference on Computer Vision
, 2000
"... . A probabilistic method for tracking 3D articulated human gures in monocular image sequences is presented. Within a Bayesian framework, we de ne a generative model of image appearance, a robust likelihood function based on image graylevel dierences, and a prior probability distribution over pose an ..."

Published online in Wiley InterScience (www.interscience.wiley.com). DOI: 10.1002/cta.347 An eight layer cellular neural network for spatio-temporal image ltering
"... Spatio-temporal lters are critical components of biologically inspired or neuromorphic algorithms for image motion analysis. In this paper, we describe eight layer cellular neural network architectures that can be used to implement these lters. Despite the apparently large number of layers, we descr ..."

Seismic data ltering with lapped transforms and hidden Markov models
"... The discrete wavelet transform (DWT) provides sparse bases for natural sig-nal and image processing. DWT is particularly successful for noise removal [1]. Recently, algorithms based on wavelet-domain hidden Markov models (HMMs) have demonstrated excellent performance for image ltering, segmentation ..."

Segmentation of textured images based on fractals and image "ltering
, 1999
"... This paper describes a new approach to the segmentation of textured gray-scale images based on image pre-"ltering and fractal features. Traditionally, "lter bank decomposition methods consider the energy in each band as the textural feature, a parameter that is highly dependent on image in ..."

A Spatial Extension of CIELAB for Digital Color Image Reproduction
, 1996
"... We describe a spatial extension to the CIELAB color metric that is useful for measuring color reproduction errors of digital images. To compute the error, digital color images are spatially #ltered using a pattern-color separable method and then converted into the CIELAB representation. Over pattern ..."
