Supression of Speckle Noise in Ultrasound Images Using Lowpass Filters
Speckle noise is one of the most critical disturbances that alter the quality of Synthetic Aperture Radar (SAR) coherent images. Speckle noise is reduced by different types of low pass filters and homomorphic filters. The range of the performance metrice of each low pass filters and Homomorphism filters determines the quality of the filtered image. The preference of the filter is determined by the performance Metrics. The results of various analyses after comparison of the performance metrics was observed and was identified that Low pass Butterworth filter achieved PSNR of 71%.
