Matching pursuit-based shape representation and recognition using scale-space

Jean-Philippe Thiran, Pierre Vandergheynst, François Mendels

In this paper, we propose an analytical low-level representation of images, obtained by a decomposition process, namely the matching pursuit (MP) algorithm, as a new way of describing objects through a general continuous description using an affine invaria ...

Affine invariant Matching Pursuit-based shape representation and recognition using scale-space

Jean-Philippe Thiran, Pierre Vandergheynst, François Mendels

In this paper, we propose an analytical low-level representation of images, obtained by a decomposition process, here the matching pursuit (MP) algorithm, as a new way of describing objects through a general continuous description using an affine invariant ...

Rotation and scale invariant shape representation and recognition using Matching Pursuit

Jean-Philippe Thiran, Pierre Vandergheynst, François Mendels

Using a low-level representation of images, like matching pursuit, we introduce a new way of describing objects through a general description using a translation, rotation, and isotropic scale invariant dictionary of basis functions. We then use this descr ...

Extraction of the optic disk boundary in digital fundus images

Jean-Philippe Thiran, François Mendels

The methods of active contours (snakes) and level sets were applied to images of the retina in order to locate the outer boundary of the optic disk. A gradient-vector-flow based active contour was used as it performed well over a large range of initial con ...

Identification of the optic disk boundary in retinal images using active contours

Jean-Philippe Thiran, François Mendels

This paper describes a technique for identifying the boundary of the optic disk in digital images of the retina, using an approach based on active contours (snakes). The optic disk is the region on the retina at which optic nerve axons enter and leave the ...
