چکیده

This paper describes an approach for texture characterization based on various wavelet decomposition transforms and its application for the discrimination of visually similar renal stone images. The proposed feature extraction algorithm applies Daubechies, Symlet, Coieflet, orthogonal and reverse biorthogonal wavelet transforms and uses approximation and detail coefficients to characterize renal stones images. This Classification is experimented on a set of twenty five (25) different stones which includes five different type shows that first order statistical, second order statistical, fast fourier transform in combination with wavelet decomposition could be a reliable method for a texture characterization. Key WordsRenal Calculi, Classification, Statistical Analysis, FFT, Texture Characterization, Wavelet Decomposition

Texture Classification of Diffused Liver Diseases Using Wavelet Transforms

Introduction: A major problem facing the patients with chronic liver diseases is the diagnostic procedure.  The conventional diagnostic method depends mainly on needle biopsy which is an invasive method. There  are  some  approaches  to  develop  a  reliable  noninvasive  method  of  evaluating  histological  changes  in  sonograms. The main characteristic used to distinguish between the normal...

A Multiresolution Bilateral Filter for Speckle Reduction in Ultrasound Kidney Images

The kidney stones (renal calculi) are the most common medical problems that occur to the people, irrespective of age group. The ultrasonography is a versatile and noninvasive imaging modality often preferred over other techniques such as CT, MRI and X-ray for kidney stone detection. It does not use any ionizing radiation for its operation. However, the main disadvantage associated with ultrasou...
