Motion blur of image is caused by relative motion between camera and photographed object during protographing. Motion-blurred image restoration is an important part of the image restoration. Image restoration is the process of recovering original image from its degraded version. This paper focuses on image restoration blurred by uniform linear motion. Principle of image restoration technique is...

Received ; accepted – 2 – ABSTRACT We present 5 filter photometry of 21 carbon stars, 15 asteroids, 15 cataclysmic variables, 6 metal-poor stars, 5 Cepheids, 1775 field stars, blue horizontal branch (BHB) stars and RR Lyrae stars in the globular clusters M 15 and M 2, two primary standards, and 19 secondary standards. The photometry was carried out using a filter set identical to that which wil...

A field study was conducted to explore the suitability of 5 pesticide deposition samplers for airborne spray and ground deposits from ultra-low-volume (ULV) space sprays. Samplers included horizontally stretched stationary cotton ribbons at 2 heights, rotating ribbon, rotating Teflon slides, and filter paper. Slides were also used for droplet-size analysis. A set of 7 samplers of each type was ...

This paper,presents an efficient VLSI architecture for the dehlocking filter in H.ZWIVT/AVC. We use an array of 8x4 &bit shift registers with reconligurable data path to support both horizontal filtering and vertical filtering on the same circuit (a parallel-in parallel-out reconfigurable FIR filter). Two SRAM modules are carefully organized not only for the storage of current macroblock data a...

End-to-end available bandwidth estimation is very important for bandwidth dependent applications, quality-of-service verification and traffic engineering. Although several techniques and tools have been developed in the past, producing precise estimations in real-time still remains challenging, mainly due to the lack of control on the measured network path and environmental conditions, such as ...

Image segmentation refers to segmenting or dividing an image which corresponds to objects or different parts of an object. The segmentation is carried out using K-means clustering algorithm, which is a fast and efficient way to segment an image. K-means is one of the most widely used algorithm. We have implemented a color based image segmentation using Kmeans clustering technique. The K-means a...

Visual detection of a line target differing in orientation from a background of lines may be achieved speedily and effortlessly. Such performance is assumed to occur early in vision and to involve filter mechanisms acting in parallel over the visual field. This study establishes orientational limits on this performance and analytically derives some generic properties of the underlying filters. ...

Ringing artifacts that appear as spurious signal near sharp transitions in a signal appear as ghosts (or) near edges. Two techniques called LPF and ASLPF is used. LPF is used for only just identifying the artifacts present in the video image. ASLPF (Adaptive Spatial Low Pass Filter) is used to identify the artifacts whether it is present in horizontal (or) vertical position (or) near edges. DCT...

As the next generation of video coding standard, High Efficiency Video Coding (HEVC) aims to reduce 50% bit rates in comparison with previous video coding standards. In order to increase the Deblocking Filter (DBF) throughput, we propose a memory of ping-pong and interlacing VLSI architecture to prevent DBF from unnecessarily waiting for pixels in both vertical and horizontal, which only takes ...

in this article, the effect of cells' radius on the behavior of wavelength switching optical filter andthe effect of the radius of the optical filters' key characteristics such as wavelength resonance onan optical filter based on photonic crystals, have been investigated. currently, the most commonapplied mechanism for designing optical filter based on photonic crystals is using twome...
