Abstract. Correlative microscopy is a methodology combining the functionality of light microscopy with the high resolution of electron microscopy and other microscopy technologies for the same biological specimen. In this paper, we propose an image registration method for correlative microscopy, which is challenging due to the distinct appearance of biological structures when imaged with di↵ere...

In Intelligent Debris Analysis, the large number of images to be processed requires signi cant time and memory resources. Moreover, image segmentation is di cult due to inconsistent illumination conditions. To address these problems, we propose a Z{shaped nonlinear transform for preprocessing that allows us to simultaneously obtain (a) a downsampled segmented image and (b) two novel features to...

Smoothed Particle Hydrodynamics SPH is a meshless Lagrangian parti cle method for solving a system of hydrodynamic equations for compressible uids SPH is especially suited for problems with free boundaries a commonplace situation in as trophysics Rather than solving the equations on a grid the equations are solved at the positions of the so called particles each representing a mass packet with ...

this paper describes an approximating solution, based on lagrange interpolation and spline functions, to treat functional integral equations of fredholm type and volterra type. this method can be extended to functional dierential and integro-dierential equations. for showing eciency of the method we give some numerical examples.

This paper describes di erent methodologies for noise reduction or denoising with applications in the eld of microscopy. An in depth study on waveletand polynomial based denoising has been performed by considering standard test images and phantom tests with moderate and high levels of Gaussian noise. Di erent thesholding methods have been tested and evaluated and in particular a novel sigmoidal...

This thesis studies the application of signal-adaptive lter banks in perceptual coding of audio with an emphasis on Wavelet Filter Banks (WFB). It provides an overview of perceptual coding of audio, the motivating psychoacoustic principles, transforms and wavelet theory. Additionally, di erent existing wavelets-based audio coding schemes are presented. The aim of most of the schemes is to overc...

Ultrasound imaging or ultrasonography is an important diagnosis method in medical analysis. It is important to segment out cavities, di erent types of tissues and organs in the ultrasound image for e ective and correct diagnosis. Human experts are very good in segmenting out the required region. But humans lack e ciency when size of dataset increases. The need of high reproducibility and need o...

Mammographic image enhancement methods are typically aimed at either improvement of the overall visibility of features or enhancement of a speci c sign of malignancy. In this paper, we present a synthesis of the two paradigms by means of image fusion. After a redundant B-spline wavelet transform decomposition is carried out, the transform coeÆcients are processed for enhancement of microcalci c...

Dynamic load balancing on hypercube multiprocessors is considered with emphasis on quantized loads. Quantized loads are divisible only in a xed size. First, we show that a direct application of the well-known Dimension Exchange Method(DEM) to quantized loads may result in di erence in assigned loads to processors as large as logN units after balancing for a hypercube of size N . Then we propose...
