Kriging Interpolation Based Ultrasound Scan Conversion Algorithm
(0) Digital scan conversion was employed in ultrasound image devices to display scanned vector data in Cartesian coordinate that were acquired with polar coordinate. So interpolation was applied to estimate unsampled pixels gray values. Most interpolation algorithms enhanced all the detail and smooth regions. A Kriging interpolation based scan conversion algorithm is proposed to distinguish detail regions and smooth regions with asymmetry operator. Detail regions are interpolated with adaptive cubic interpolation and other smooth regions with Kriging interpolation. This algorithm preserves smooth regions and enhances detail regions in result ultrasound images. Experiment results indicate the effectiveness of the proposed algorithm.
