Augmenting Corner Descriptors
A failing of many grey-level corner detectors is that they do not extract most of the attributes of a corner apart from its strength. This paper provides several post-processing techniques for determining additional corner attributes (i.e. colour, orientation, subtended angle, and contrast). Corner matching processes can use this additional information to resolve otherwise ambiguous corresponde...
متن کاملObject Class Detection and Classification using Multi Scale Gradient and Corner Point based Shape Descriptors
This paper presents a novel multi scale gradient and a corner point based shape descriptors. The novel multi scale gradient based shape descriptor is combined with generic Fourier descriptors to extract contour and region based shape information. Shape information based object class detection and classification technique with a random forest classifier has been optimized. Proposed integrated de...
متن کاملCorner validation based on extracted corner properties
We developed a method to validate and filter a large set of previously obtained corner points. We derived the necessary relationships between image derivatives and estimates of corner angle, orientation and contrast. Commonly used cornerness measures of the autocorrelation matrix estimates of image derivatives are expressed in terms of these estimated corner properties. A candidate corner is va...
متن کاملStrongly nil-clean corner rings
We show that if $R$ is a ring with an arbitrary idempotent $e$ such that $eRe$ and $(1-e)R(1-e)$ are both strongly nil-clean rings, then $R/J(R)$ is nil-clean. In particular, under certain additional circumstances, $R$ is also nil-clean. These results somewhat improves on achievements due to Diesl in J. Algebra (2013) and to Koc{s}an-Wang-Zhou in J. Pure Appl. Algebra (2016). ...
متن کاملMeasurements Corner
This paper describes a statistical signal-processing method for exploiting narrowband bistatic RF measurements to detect and track moving people (hereafter referred to as "dismounts"). In our approach, RF measurements are made by a constellation of narrowband radar units, arranged around a surveillance region. There are several benefits of narrowband radar in this application, which we describe...
