An unsupervised color texture synthesis-by analysis method is described. The texture is reproduced to appear perceptually similar to a given prototype by copying its statistical properties up to the second order. The synthesized texture is obtained at the output of a single-input three-output nonlinear system driven by a realization of a white Gaussian random field. Significant complexity reduc...

Noise reduction for mobile telephony applications is considered. A power spectral density error analysis is applied to the method of power subtraction. A minimum power spectral density error subtraction factor is derived, where the resulting factor depends on introduced quality factors. The outcome of the analysis is compared with experimental work as well as standardized noise reduction schemes.

progressive loss of bone mineral density around the femora! component of total hip replacement continues to pose a threat to long term prosthetic survival. a linear study was undertaken to measure bone mineral density on a monthly basis following total hip arthroplasty in 11 male patients. the opposite femur was used as the control measurement. bone mineral density was unchanged at two months f...

Background: Hirsutism can result in cosmetic and psychological problems in women. Because of diverse etiological factors, treatment with a single drug is not usually successful. On the other hand, treatment of Hirsutism can be associated with adverse effects. Objective: To evaluate the efficacy of a herbal ointment consisted of leguminosea spp. and zingiberaceae spp. extracts in reduction of ha...
