Modeling Gestalt laws for classification
9th IEEE International Conference on Cognitive Informatics (ICCI'10), 2010The k-nearest neighbors classifier is simple and often results in good classification performance on problems with unknown and non-normal distributions. However, its selected nearest neighbors on noisy, sparse, or imbalanced data are often inconsistent with our intuition and in turn leads to the worse performance.

Ecological statistics of Gestalt laws for the perceptual organization of contours
Journal of Vision, 2002 Although numerous studies have measured the strength of visual grouping cues for controlled psychophysical stimuli, little is known about the statistical utility of these various cues for natural images. In this study, we conducted experiments in which human participants trace perceived contours in natural images.

Local and Global Gestalt Laws: A Neurally Based Spectral Approach [PDF]
Neural Computation, 2017 This letter presents a mathematical model of figure-ground articulation that takes into account both local and global gestalt laws and is compatible with the functional architecture of the primary visual cortex (V1). The local gestalt law of good continuation is described by means of suitable connectivity kernels that are derived from Lie group theory

Grouping in object recognition: The role of a Gestalt law in letter identification [PDF]
Cognitive Neuropsychology, 2009 The Gestalt psychologists reported a set of laws describing how vision groups elements to recognize objects. The Gestalt laws "prescribe for us what we are to recognize 'as one thing'" (Kohler, 1920). Were they right? Does object recognition involve grouping?

Computational Layout Perception using Gestalt Laws
Proceedings of the 2016 CHI Conference Extended Abstracts on Human Factors in Computing Systems, 2016We present preliminary results on computational perception of interactive layouts. Our goal is to algorithmically estimate how users perceive a layout. Potential applications range from automated usability evaluation to computer-generated and adaptive interfaces.

Gestalt: From Phenomena to Laws
2000The Gestalt phenomena of grouping in space and in space-time (proximity, similarity, good continuation, common fate, apparent motion and so on) are an essential foundation of perception. Yet they have remained fairly vague, experimentally intractable, and unqualified.

A novel framework for automatic trimap generation using the Gestalt laws of grouping
Proceedings of SPIE, 2015In this paper, we are concerned with unsupervised natural image matting. Due to the under-constrained nature of the problem, image matting algorithms are usually provided with user interactions, such as scribbles or trimaps. This is a very tedious task and may even become impractical for some applications.
