Perceptual Organization of Shape
Computing the correct bounding contours of objects in complex natural scenes is generally thought to be one of the harder computer vision problems, and the state of the art is still quite far from human performance, when human subjects are given an arbitrary amount of time to delineate the shape of these contours [1]. How do we explain this gap? One possibility is that, when given enough time, ...
متن کاملA Perceptual Shape Descriptor
In this study, we present the two dimensional object silhouette by a one dimensional descriptor, which preserves the perceptual structure of its shape. The proposed descriptor is based on the moments of the angles between the bearings of a point on the boundary, in a set of neighborhood systems. At each point on the boundary, the angle between a pair of bearings is calculated to extract the top...
متن کاملPerceptual regularization functionals for natural image restoration
Regularization constraints are necessary in inverse problems such as image restoration, optical flow computation or shape from shading to avoid the singularities in the solution. Conventional regularization techniques are based on some a priori knowledge of the solution: usually, the solution is assumed to be smooth according to simple statistical image or motion models. Using the fact that hum...
متن کاملPerceptual learning of object shape.
Recognition of objects is accomplished through the use of cues that depend on internal representations of familiar shapes. We used a paradigm of perceptual learning during visual search to explore what features human observers use to identify objects. Human subjects were trained to search for a target object embedded in an array of distractors, until their performance improved from near-chance ...
متن کاملDuality Principle for Image Regularization and Perceptual Color Correction Models
In this paper, we show that the anisotropic nonlocal total variation involved in the image regularization model of Gilboa and Osher [15] as well as in the perceptual color correction model of Bertalmı́o et al. [4] possesses a dual formulation. We then obtain novel formulations of their solutions, which provide new insights on these models. In particular, we show that the model of Bertalmı́o et al...
