in this paper we construct antimagic labelings of the regular complete multipartite graphs and we also extend the construction to some families of regular graphs.

In this paper, high-efficient lifting-based architectures for the 5/3 forward and inverse discrete wavelet transform (DWT) are proposed. The proposed parallel and pipelined architecture consists of a horizontal filter (HF) and a vertical filter (VF). The system delays of the proposed architectures are reduced. Filter coefficients of the biorthogonal 5/3 wavelet low-pass filter are quantized bef...

The proposed parallel and pipelined architecture consists of a horizontal filter (HF) and a vertical filter (VF). The system delays of the proposed architectures are reduced. Filter coefficients of the biorthogonal 5/3 wavelet low-pass filter are quantized before implementation i...

In this paper, a high-efficient lined-based architecture for the 9/7 discrete wavelet transform (DWT) based on lifting scheme is proposed. The proposed parallel and pipelined architecture consists of a horizontal filter (HF) and a vertical filter (VF). The critical path of the proposed architecture is reduced. Filter coefficients of the biorthogonal 9/7 wavelet low-pass filter are quantized bef...

Semi-automated processing of microscopy images can significantly enhance the capacity for objective nanostructure characterization. However, background complexity, intricate object features and overlapping of objects can make this a difficult task. Here we describe use of the Gabor filter [1, 2] to facilitate the identification and outlines of the top surfaces of nanowires of zinc oxide (ZnO), ...

Many problems in early vision are ill posed 1. Edge detection is a typical example. This paper applies regular-ization techniques to the problem of edge detection. We derive an optimal filter for edge detection with a size controlled by the regularization parameter and compare it to the Gaussian filter. A formula relating the signal-to-noise ratio to the parameter is derived from regularization...

Motion vectors (MVs) characterize the movement of pixel blocks in video streams and are readily available. MVs not only allow us to avoid expensive feature transform and correspondence computations but also provide the motion information for both the environment and moving obstacles. This enables us to develop a new framework that is capable of simultaneous localization, scene mapping, and movi...

It is well known that common subexpression elimination techniques minimize the two main cost metrics namely logic operators and logic depths in realizing finite impulse response (FIR) filters. Two classes of common subexpressions occur in the canonic signed digit representation of filter coefficients, called the horizontal and the vertical subexpressions. Previous works have not addressed the t...
