Mining change patterns in time series high-resolution SAR images

open access: yesThe Journal of Engineering, 2019
Here, the authors use the K-Shape algorithm, which is based on a z-normalised version of cross-correlation distance measure, to extract change patterns from time series synthetic aperture radar (SAR) images.

Depth and Shape Estimation from Focus in Scanning Electron Microscope for Micromanipulation.

open access: yes, 2013
International audienceInter-object depth estimation is always a major concern for micromanipulation using scanning electron microscope (SEM). So far, various methods have been proposed for estimating this depth based on stereoscopic imaging. Most of them

Medial Axis for the Cortical Representation of 3D Shape

open access: yesi-Perception, 2012
Representation of shape is a fundamental problem in vision science. Neurophysiological studies of macaque have reported that neurons in the primary visual cortex (V1) respond to Medial Axis (MA) of 2D surface, and that those in higher cortex (IT) respond
