Title
(EN) Security check image artifact removing method utilizing region search and pixel value suppression
(ZH) 一种利用区域搜索和像素值抑制的安检图像伪影去除方法
Abstract
(EN) The invention discloses a security check image artifact removing method using region search and pixel value suppression. The method comprises the following steps of calculating a human head center rowcoordinate; judging a pseudo-pixel between two legs; judging pseudo-pixel between arms and trunks; and suppressing the pixel values of the pseudo image pixels to obtain a security check image withoutartifacts. According to the method, the aArtifacts between the two legs and the artifacts between the arms and the trunks are searched for in the fixed area through the area search method according to the fixed posture during human body security check, computer resources and search time can be saved, and the artifact search efficiency is improved.
(ZH) 本发明公开了一种利用区域搜索和像素值抑制的安检图像伪影去除方法,包括以下步骤:计算人体头部中心行坐标;判决双腿间伪影像素;判决手臂躯干间伪影像素;对伪影像素的像素值进行抑制,得到去除伪影的安检图像。本发明根据人体安检时的固定姿势,利用区域搜索方法在固定区域内搜索双腿间伪影和手臂躯干间伪影,有利于节省计算机资源和搜索时间,提高伪影搜索效率。
