Perceptual organization with image formation compatibilities
نویسندگان
چکیده
The work presents a methodology contributing to boundary extraction in images of approximate polyhedral objects. We make extensive use of basic principles underlying the process of image formation and thus reduce the role of object-specific knowledge. Simple configurations of line segments are extracted subject to geometricphotometric compatibilities. The perceptual organization into polygonal arrangements is based on geometric regularity compatibilities under projective transformation. The combination of several types of compatibilities yields a saliency function for extracting a list of most salient structures. Based on systematic measurements during an experimentation phase the adequacy and degrees of compatibilities are determined. The methodology is demonstrated for objects of various shapes located in cluttered scenes.

Compatibilities for Boundary Extraction

متن کاملCompatibilities for the Perception-Action Cycle
We apply an eye-on-hand Robot Vision system for treating the following three tasks: (a) Tracking objects for obstacle avoidance; (b) Arranging certain viewing conditions; (c) Acquiring an object recognition function. The novelty is the use of so-called compatibilities between motion features and view sequence features. Under real image formation, compatibilities are more general and appropriate...

Objective: A variety of evidence demonstrate altered perceptual functioning during visual processing in the brain of children with autism.it possibly is related to or the cause other diagnostic symptom in autism spectrum. In the present study visual perceptual organization in autistic children is studied. These processes require central coherence and typical functional connectivity among neural...
متن کاملImage authentication using LBP-based perceptual image hashing
Feature extraction is a main step in all perceptual image hashing schemes in which robust features will led to better results in perceptual robustness. Simplicity, discriminative power, computational efficiency and robustness to illumination changes are counted as distinguished properties of Local Binary Pattern features. In this paper, we investigate the use of local binary patterns for percep...
متن کاملDynamic Perceptual Organization Computing Spatiotemporal Relations for Dynamic Perceptual Organizationy
To date, the overwhelming use of motion in computational vision has been to recover the three-dimensional structure of the scene. We propose that there are other, more powerful, uses for motion. Toward this end, we deene dynamic perceptual organization as an extension of the traditional (static) perceptual organization approach. Just as static perceptual organization groups coherent features in...
