Spatial Skills Associated With Block-Building Complexity in Preschoolers
Frontiers in Psychology, 2020 Block building is a popular play activity among young children and is also used by psychologists to assess their intelligence. However, little research has attempted to systematically explore the cognitive bases of block-building ability.

Perceptually Motivated Shape Context Which Uses Shape Interiors
, 2012 In this paper, we identify some of the limitations of current-day shape matching techniques. We provide examples of how contour-based shape matching techniques cannot provide a good match for certain visually similar shapes.

Retinal encoding of ultrabrief shape recognition cues. [PDF]
PLoS ONE, 2007 Shape encoding mechanisms can be probed by the sequential brief display of dots that mark the boundary of the shape, and delays of less that a millisecond between successive dots can impair recognition.

Shape recognition by bag of skeleton-associated contour parts [PDF]
Pattern Recognition Letters, 2014 We associate a contour point with an object thickness value.We propose a new descriptor to combine both contour and skeleton information.Our method achieves the state-of-the-arts results on several shape dataset.

Shape and Texture Combined Face Recognition for Detection of Forged ID Documents [PDF]
, 2016 This paper proposes a face recognition system that can be used to effectively match a face image scanned from an identity (ID) doc-ument against the face image stored in the biometric chip of such a document. The purpose of this specific face recognition
