Corner detection by local histograms of contourchain code

Abstract

totally reflective when switched on, or energised. The reflected sig rial produced by this structure when screen i is switched on and all otber screens are switched off is therefore s,(t) = cos(ot + 2434. The reflected signal s,(t) may also be expressed in terms of in-. phase and quadrature components as sr(t) = cos(wt)cos(2i!3d)s in(cot)sin(2iPd).

Performance evaluation of corner detectors using consistency and accuracy measures

“…Quddus and Fahmy [45] presented a wavelet-based scheme for detection of corners on 2D planar curves. Arrebola et al [3] introduced different corner detectors based on local and circular [4] histogram of contour chain code. Zhang and Zhao [63] considered a parallel algorithm for detecting dominant points on multiple digital curves.…”

Robust image corner detection through curvature scale space

“…Rangarajan et al [22] proposed a detector which tries to find an analytical expression for an optimal function whose convolution with the windows of an image has significant values at corner points. Arrebola et al [1] introduced corner detection by local histograms of contour chain code. Shilat et al [23] worked on ridge's corner detection and correspondence.…”
