Method for extracting barium information in image

Abstract

The invention relates to a method for extracting barium agent information in an image. The method comprises the following steps of: acquiring an X-ray image comprising a throat part, and acquiring a morphological characteristic image by using a morphological algorithm; performing edge detection on the morphological characteristic image to obtain a pharyngeal image; and extracting barium agent information in the pharyngeal image by using a three-frame difference method. Compared with the prior art, the volume of a fluid barium agent can be measured, the specific behavior of the barium agent canbe judged, the barium agent information can be extracted from a dynamic background, and noise interference is resisted, and the detected barium agent information is more precise.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method for extracting barium information from an image. Background technique [0002] It is difficult to extract barium information from X-ray images including the throat. First, swallowing fluid barium is very fast. Usually, the fluid passes through the throat within 1 to 2 seconds, which is difficult to capture dynamically. X-ray images are redundant and difficult to unify their quality. [0003] As for the detection of fluid barium, it involves the detection of moving objects in sequence images, and detects the changed area and extracts it from the background area. The difficulties in the detection of moving objects for barium are as follows: 1. The moving object is irregular, and it is only a perspective view when viewed from the side. It is impossible to specifically measure the volume of fluid barium, and it is impossible to judge the specific behavior of barium. 2. Dyna...
