Title: Automatic detection method of foreground and background of digital radiographic image
Inventor: BEN KEI YAN
IPC: G06T5/00
Filed: 1993-06-29
Abstract: PURPOSE: To automatically separate the desirous area (an image picked-up body part) and nondesirous part (a foreground area irradiated with an extremely small amount of radiation or a background area around a body part irradiated no-attenuation radiation by using a radiation limiter) of a digital radiographic image from each other. CONSTITUTION: The edge of image signals is detected (24) and the image signals are resolved into non-superposed adjacent block sets of pixel signals (26). Then the pixel signal blocks are classified into homogeneous blocks and nonhomogeneous blocks as the functions of the edge density and variation (28) and, by applying a syntax rule for detecting the nonhomogeneous blocks of pixel signals in the foreground and background and homogeneous blocks of pixel signals in an object and detailing the blocks in which the object and foreground and background coexists in a mixing state (30), separated image signals are generated (32).

Abstract: PURPOSE:To always keep the surface of a turning roller clean by bringing a conductive turning roller into contact with the transfer surface of a mobile member passing through a transfer area. CONSTITUTION:While moving a transfer material carrying belt 21, the belt is brought into contact with a metallic roller 40 arranged ahead of the transfer position in which visible images formed on photosensitive drums 1a, 1b, 1c and 1d, are transferred. Electric field force such as coulomb force on the surface of the metallic roller 40 attracts the stain of toner, paper powder, etc., by bringing them into contact with the metallic roller 40. The stain attracted to the metallic roller 40 is conveyed by holding it on its surface, and moved to the position of a blade 41 slightly pressing against the metallic roller 40, and removed by the blade 41. Thus, frictional heat is not generated. Even if the stain is made of resin powder with a low fusing point, it never aggregates, is nor fused, thereby improving cleaning efficiency.
