A Mean Curvature Based Primal Sketch to Study the Cortical Folding Process from Antenatal to Adult Brain

In this paper, we propose a new representation of the cortical surface that may be used to study the cortex folding process and to recover foetus sulcal roots usually burried in the depth of adult brains. This representation is a primal sketch derived from a scale space computed for the mean curvature of the cortical surface. This scale-space stems from a geodesic diffusion equation conditional...

Active Detection and Classsification of Junctions by Foveation with a Head-Eye System Guided by the Scale-Space Primal Sketch

Analysis of brain activation patterns using a 3-D scale-space primal sketch.

A fundamental problem in brain imaging concerns how to define functional areas consisting of neurons that are activated together as populations. We propose that this issue can be ideally addressed by a computer vision tool referred to as the scale-space primal sketch. This concept has the attractive properties that it allows for automatic and simultaneous extraction of the spatial extent and th...

Perceptual Scale-Space and Its application

When an image is viewed at decreasing resolutions in a Gaussian pyramid, information is lost gradually. Amid continuous intensity changes across scales, there are “quantum jumps” or “perceptual transitions” in our inner representation. In this paper, we study a representational paradigm called the perceptual scale-space which augments the Gaussian pyramid in traditional image scale-space theory...
