چکیده
The imaging system involves an image produced from a reeection by a spherical mirror to produce a 360 projection of the environment. This paper extends previous work on an image-based navigation system in which the 360 view is compressed into a circular waveform. A navigation task is speciied as a sequence of homing tasks on target locations. This is accomplished by matching landmarks from the current view with the next target view. This paper provides a new method for matching using qualitative geometric features of each of the wave-forms. In addition, a geometric analysis allows us to do 3D reasoning about the environment, which is suucient for computing the rotation and translation between the current location and the target location. It may eventually allow acquisition of a 3D model of the environment. We show that the system performs reliably in an indoor environment.

A Novel Technique for Steganography Method Based on Improved Genetic Algorithm Optimization in Spatial Domain
This paper devotes itself to the study of secret message delivery using cover image and introduces a novel steganographic technique based on genetic algorithm to find a near-optimum structure for the pair-wise least-significant-bit (LSB) matching scheme. A survey of the related literatures shows that the LSB matching method developed by Mielikainen, employs a binary function to reduce the numbe...

Land cover is defined as the physical material of the surface of the earth, including different vegetation covers, bare soil, water surface, various urban areas, etc. Land cover and its changes are very important and influential on the Earth and life of living organisms, especially human beings. Land cover change monitoring is important for protecting the ecosystem, forests, farmland, open spac...
متن کاملSomebody helps me: Travel video scene detection using web-based context
We conduct video scene detection with the aids of web-based context, especially for travel videos captured by amateur photographers in journeys. Correlations between personal videos and predefined travel schedules, which are used to retrieve related data from general-purpose image/video search engines, are discovered. Because scene boundaries are clearly defined in travel schedules, we segment ...

We show that the segment endpoint visibility graph of any finite set of 2n line segments contains a planar matching that does not use any segment edge, if the line segments in our set are convexly independent.

Introduction: It is recommended that the physician apply at least a semi-quantitative segmental scoring system in myocardial perfusion SPECT. We aimed to assess the agreement between automated semi-quantitative analysis using QPS (quantitative Perfusion SPECT) software and visual approach for calculation of summed stress score (SSS), summed rest score (SRS) and summed difference score (SDS). ...

The so-called Tethered Space Robot (TSR) is a novel active space debris removal system. To solve its problem of non-cooperative target recognition during short-distance rendezvous events, this paper presents a framework for a real-time visual servoing system using non-calibrated monocular-CMOS (Complementary Metal Oxide Semiconductor). When a small template is used for matching with a large sce...
