Location technologies provide a way to associate information to a user's location. The
authors developed a system that processes a cell-phone camera image and matches …

Corner detectors have many applications in computer vision and image identification and
retrieval. Contour-based corner detectors directly or indirectly estimate a significance …

An algorithm to separate touching grain kernels using an elliptic Fourier series
approximation, based on boundary curvature values, is presented. The Fourier …

An algorithm for polygonal approximation based on dominant point (DP) deletion is
presented in this paper. The algorithm selects an initial set of DPs and starts eliminating …

A polygonal approximation technique using reverse polygonization is presented in this
paper. The reverse polygonization starts from an initial set of dominant points ie break …

In this paper, we present a novel non-parametric polygonal approximation algorithm for
digital planar curves. The proposed algorithm first selects a set of points (called cut-points) …

A new approach to polygonal approximation is presented in this paper. It starts from an initial
set of dominant points (break points), where the integral square error from a given shape is …

A new corner detector for planar curves is presented in this paper. This algorithm finds
corner by sliding set of three rectangles along the curve and counting number of contour …

Increasingly, cell phones are used to browse for information while location systems assist in
gathering information that is most appropriate to the user's current location. We seek to take …

Corner detection is an important step in many computer vision applications. A large number
of corner detection algorithms were already developed. An exhaustive review of the existing …
