Vein pattern recognition is one of the recent methods for human identification which have advantages over other biometrics (i.e. fingerprint, face, and iris). However; due to vein image capturing methods, vein row images usually carry distortions. Preprocessing is needed to enhancing the raw captured vein images. In this paper, we examine six recent vein image enhancement techniques; we coded t...

A new multi-layer substrate integrated waveguide (SIW) structure is developed to design dual-band evanescent-mode band-pass filters (BPFs). Two independent series LC circuits are implemented by incorporating metallic irises in the different layers of the structure. The combination of the metallic irises with capacitive-plates is embedded inside the SIW to independently excite two evane...

Background: Boron Neutron Capture Therapy (BNCT) is a very promising treatment for patients suffering gliobastoma multiforme, an aggressive type of brain cancer, where conventional radiation therapies fail. Thermal neutrons are suitable for the direct treatment of cancers which are located at near-tissue-surface deep-seated tumors need harder, epithermal neutron energy spectra. Materials and Me...

Periodic noise widely appears in raw images and is often accompanied with white noise. The removal of such compound noise is a challenging problem in image processing. To avoid using the time-consuming methods such as Fourier transform, a simple and efficient spatial filter called optimal soft morphological filter (OSMF) is proposed in this paper. The filter is a combination of basic soft morph...

104404-8080 IJET-IJENS © August 2010 IJENS I J E N S  Abstract— Discrete Wavelet Transform (DWT) is an efficient tool for signal and image processing applications which has been utilized for perfect signal reconstruction. In this paper, twenty seven optimum combinations of three different wavelet filter types, three different filter reconstruction levels and three different kinds of signal for...

If a system for lossless compression of images applies a decorrelation step, this step must map integer input values to integer output values. This can be achieved, for example, using the integer wavelet transform (IWT). The non-linearity, introduced by the obligatory rounding steps, is the main drawback of the IWT, since it deteriorates the desired filter characteristic. This paper discusses d...

hand gesture recognition is very important to communicate in sign language. in this paper, an effective object tracking and hand gesture recognition method is proposed. this method is combination of two well-known approaches, the mean shift and the motion detection algorithm. the mean shift algorithm can track objects based on the color, then when hand passes the face occlusion happens. several...

When the extension state of non-ellipsoidal extended target (NET) changes, performance traditional multiple tracking algorithms based on constant number sub-objects will decrease. To solve this problem, paper proposes a gamma Gaussian inverse Wishart probability hypothesis density filter for targets with varying sub-objects, called VN-NET-GGIW-PHD filter. In proposed filter, each NET is conside...

In this paper, we have designed a new variable latency adder and its implementation of decimation filter. There are multiple ways to implement a decimationfilter. This filter design combination of CIC (cascaded-integrator-comb) filter and HB (half band) filter as the decimator filter to reduce the frequency sample rate conversion and detail of the implementation step to realize this design in h...
