Volume Completion Between Contour Fragments at Discrete Depths
Building on the modal and amodal completion work of Kanizsa, Carman and Welch showed that binocular stereo viewing of two disparate images can give rise to a percept of 3D curved, nonclosed illusory contours and surfaces. Here, it is shown that binocular presentation can also give rise to the percept of closed curved surfaces or volumes that appear to vary smoothly across discrete depths in bin...
متن کاملAnisotropic contour completion
In this paper we introduce a novel application of the diffusion tensor for anisotropic image processing. The Anisotropic Contour Completion (ACC) we suggest consists in extending the characteristic function of the open curve by means of a degenerated diffusion tensor that prevents any diffusion in the normal direction. We show that ACC is equivalent to a dilation with a continuous elliptic stru...
متن کاملObject Detection Using Contour Fragments
In this paper, we present a novel object detection scheme using contour fragments. The template fragments are extracted by decomposing the template contour. The hinge angle, contour direction and partial Hausdorff distance (PHD) are used to match the fragments in the edge image. Then, the Multiclass Discriminative Field (MDF) is used to select the matches. With these selected matches and their ...
متن کاملVolume completion.
The visual system completes image fragments into larger regions when those fragments are taken to be the visible portions of an occluded object. Kellman and Shipley (1991) argued that this "amodal" completion is based on the way that the contours of image fragments "relate." Contours relate when their imaginary extensions intersect at an obtuse or right angle. However, it is shown here that con...
متن کاملTERZIĆ: SHAPE DETECTION WITH NEAREST NEIGHBOUR CONTOUR FRAGMENTS 1 Shape Detection with Nearest Neighbour Contour Fragments
We present a novel method for shape detection in natural scenes based on incomplete contour fragments and nearest neighbour search. In contrast to popular methods which employ sliding windows, chamfer matching and SVMs, we characterise each contour fragment by a local descriptor and perform a fast nearest-neighbour search to find similar fragments in the training set. Based on this idea, we sho...
