Abstract

Phase-only filters (POF) are studied for speckle reduction and edge detection in ultrasonic images. A methodology is developed for selecting the filters and compounding the filtered outputs. Studies on four speckled images show that the parametric images of compounded phases highlighted the boundaries. Estimating the heterogeneity index defined as the ratio of the arithmetic to the geometric mean of the magnitudes, the boundaries were also highlighted, providing a second means of detecting boundaries. This technique based on diversity created through a bank of POF reduces the speckle as well as highlights the boundaries of targetlike regions.
