An innovative technique for segmentation of color images is proposed. The technique implements an approach based on thresholding of the hue histogram. A new function for detecting valleys of the histogram has been devised and tested. A novel blurring algorithm for noise reduction that works effectively when used over hue image, has been employed.

Remote Masking (RM) (a rise in threshold for low-frequency tones when the ear is exposed to a high intensity noise band of high frequency) has been attributed to mechanical nonlinear distortion of the cochlear partition, as an effect of the envelope of a nonuniform signal. Clinical studies using RM have revealed RM is normal only when both the(More)
Remote masking (RM) consists of a rise of the threshold for low-pitched tones when the ear is exposed to a high-frequency noise band delivered with high intensity. This phenomenon has been attributed to mechanical non-linear distortion of the cochlear partition, as an effect of the envelope of a non-uniform signal. The authors studied RM in patients(More)
The authors have studied the relations between crossed and uncrossed acoustic stapedius reflex thresholds in presbyacusic subjects in order to verify whether ageing produces brain stem auditory lesions. The results showed in 55% of the presbyacusics a brain stem disorder characterized by the absence of one, several or all the acoustic reflexes; very often(More)
