AUTOMATIC BACKGROUND RECOGNITION AND REMOVAL (ABRR) IN PROJECTION DIGITAL RADIOGRAPHIC IMAGES (PDRI)

摘要

A method (Fig. 1) and system (Fig. 13) for removal of background from projected digital radiograph images which utilizes statistical methods to identify background pixel candidates and probable background edges of a PDRI. Thresholds for evaluating the probable background edges are determined utilizing statistical results and a reliable estimation of background removal is performed.
