Ubiquitous commerce (u-commerce) is an emerging area of ubiquitous computing. Electronic commerce (e-commerce), mobile commerce (m-commerce), and ubiquitous commerce are based not only on development concerns of Internet but also technological and organizational innovations arising from the combination of telecommunications and organizational computing. In u-commerce, service is provided according...
In this paper, Vertex Component Analysis based spectral unmixing is proposed as a preprocessing stage for hyperspectral image compression. The two approaches generally used in hyperspectral image compression are to compress it as a 3D cube or apply two stages of data reduction (spectral and spatial). In the first method, the hyperspectral image is considered as a cube and 3-D compression is applied...
Image processing is the most frequently used technique in computer vision like target detection of monitored target images to recognize background clutter and observed target images. To evaluate the performance of various image processing algorithms, image clutter metrics are very important and useful factors for the better visual conception such as increasing the probability of detection, decreasing...
Therein under, the document covers the reasons of outliers' appearance upon the observation error function of discreteness when changing a sample rate in an analog-to-digital converter (ADC) which is used for measurement of the signal's root mean square (RMS). We evaluate an upper bound for measurement uncertainty of discreteness depending on a number of bits in the ADC.
We developed an automated technique for non-rigid image registration as a basis for tracking the heart in contrast-enhanced cardiac magnetic resonance (CMR) image sequences. The goal of the present work was to validate this technique against conventional manual analysis. Our approach is based on a multi-scale extension of the normalized 2D cross-correlation algorithm in combination with level-set...
