Texture Classification using Angular and Radial Bins in Transformed Domain

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...

Audio Time Stretching Using Fuzzy Classification of Spectral Bins

A novel method for audio time stretching has been developed. In time stretching, the audio signal’s duration is expanded, whereas its frequency content remains unchanged. The proposed time stretching method employs the new concept of fuzzy classification of time-frequency points, or bins, in the spectrogram of the signal. Each time-frequency bin is assigned, using a continuous membership functi...

Angular Radial Edge Histogram

The Angular Radial Edge Histogram (AREH) extends prior work on a compact image representation based on geometric distributions of edge pixels. Histograms of edge pixels are computed along the dimensions of angle and radius. Fourier transform is applied to accommodate rotation invariance. It achieves invariance for scale variation, in-plane rotation, and translation. By using a grid-based approa...
