“…Together with the distances, a single point of interest pi is encoded in two ndimensional vectors D p i and Θ p i . Our proposed point descriptor differs from the methods [5] and [3] in the following aspects. Firstly, we only consider the feature vectors from points of interest instead of roughly uniform spacing or randomly picking for selecting sample points.…”

“…Secondly, the proposed point descriptor is naturally translation and rotation invariant 1 . However, approaches in [5,3] are not intrinsically rotation invariant. In order to solve this problem, they use the tangent angle on each point to turn the shape.…”

“…Kimia (2003) presented the validity of skeletons from the psychophysical and neurophysiological perspectives. Also, researchers are exploring methods that recognize objects by appropriately matching parts of their skeletons (Bai & Latecki, 2008;Feinen, Yang, Tiebe, & Grzegorzek, 2014). Furthermore, these methods are being extended to realistic images with cluttered backgrounds, where an object is detected by applying contours of its parts to edges extracted for an image (Bai, Wang, Latecki, Liu, & Tu, 2009).…”
