1-14 (October 2014)Abstract
In the literature a large number of linear and nonlinear denoising approaches for ultrasonic B-mode images. The main purpose of this paper is to test the effect of hybridization of the Log Gabor filter with the otheapproaches. The log-Gabor functions, by definition, always have no DC component, and secondly, the transfer function of the log Gabor function has an extended tail at the high frequency end. Results show that thhybridization of the Log Gabor with the Median filter gives the best output images and PSNR output values.
