Learning Robust Shape-Indexed Features for Facial Landmark Detection
Applied Sciences, 2022 In facial landmark detection, extracting shape-indexed features is widely applied in existing methods to impose shape constraint over landmarks. Commonly, these methods crop shape-indexed patches surrounding landmarks of a given initial shape.

Detecting shapes in noise: tuning characteristics of global shape mechanisms [PDF]
Frontiers in Computational Neuroscience, 2013 The proportion of signal elements embedded in noise needed to detect a signal is a standard tool for investigating motion perception. This paradigm was applied to the shape domain to determine how local information is pooled into a global percept. Stimulus arrays consisted of oriented Gabor elements that sampled the circumference of concentric radial ...

CSGNet: Neural Shape Parser for Constructive Solid Geometry
, 2018 We present a neural architecture that takes as input a 2D or 3D shape and outputs a program that generates the shape. The instructions in our program are based on constructive solid geometry principles, i.e., a set of boolean operations on shape ...

Vision Research, 1999 Detectability of contours may be affected by long-range interactions between neurons in early stages of visual cortex. Specifically, neurons with receptive fields arrayed along the length of a contour may facilitate each other in a position- and orientation-dependent manner.

A New Method for Haptic Shape Discriminability Detection
Applied Sciences, 2021 Touch shape discrimination is not only closely related to tactile mechanoreceptors but also higher cognitive function. However, previous shape discrimination methods are difficult to complete in a short time, and the devices are complicated to operate ...

Representation and detection of deformable shapes [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2003 We describe some techniques that can be used to represent and detect deformable shapes in images. The main difficulty with deformable template models is the very large or infinite number of possible nonrigid transformations of the templates. This makes the problem of finding an optimal match of a deformable template to an image incredibly hard. Using a
