Voxel based non-rigid registration of images involves finding a similarity maximising transformation that deforms a source image to the coordinate system of a target image. In order to do this, interpolation is required to estimate the source intensity values corresponding to transformed target voxels. These interpolated source intensities are used when calculating the similarity measure being ...

In this paper, we describe an accurate and effective event detection method to detect events from Twitter stream. It detects events using visual information as well as textual information to improve the performance of the mining. It monitors Twitter stream to pick up tweets having texts and photos and stores them into database. Then it applies mining algorithm to detect the event. Firstly, it d...

In this study, we propose the gesture recognition algorithm using support vector machines (SVM) and histogram of oriented gradient (HOG). Besides, also use CNN model to classify gestures. We approach select techniques applying problem controlling for robotic system. The goal is detect gestures with real-time processing speed, minimize interference, reduce ability capture unintentional Static co...

We witness many people who face disabilities like being deaf, dumb, blind etc. They a lot of challenges and difficulties trying to interact communicate with others. This paper presents new technique by providing virtual solution without making use any sensors. Histogram Oriented Gradient (HOG) along Artificial Neural Network (ANN) have been implemented. The user makes web camera, which takes in...

Image registration has always been an important research topic. This paper proposes a novel method of constructing descriptors called the histogram oriented local binary pattern descriptor (HOLBP) for fast and robust matching. There are three new components in our algorithm. First, we redefined gradient angle calculation template to make it more sensitive edge information. Second, proposed cons...

A gradient-based image analysis technique is applied to a class of non-Fourier stimuli. To create the stimuli, n translating sine waves with identical spatial and temporal frequencies, but separated by 2pi/n radians, are spatially randomly sampled to produce a P(n) stimulus. For n>or=2, the stimuli are non-Fourier. Local image gradients are represented in the form of a gradient plot, a histogra...

Since 1990 the project ‘Climate Change in the Arid Andes’ has been focusing on past climate and environmental conditions in the high mountain range of the north Chilean Andes (18 S– 28 S). The extreme aridity of this region is shown by the absence of glaciers, even at the highest altitudes above 6700 m a.s.l. More knowledge of the present climatic situation is needed to interpret the proxy data...

Abstrul-Thb paper describes an experimental ktur ing system wherein fixel reaction forces, workpiece loading, and workpiece displacements are measured during simulated fixturing operations. The system's configuration, its measurement principles, and tests to characterize its performance are summarized. This system is used to experimentally determine the relationship between workpiece displaceme...
