A method for calculating and comparing evaluation indices for a signal system of an intersection includes: a traffic statistical information generation step of receiving image information in real time through cameras to derive traffic object information including traffic volume for each driving direction and traffic volume for each lane on a corresponding road at a preset first cycle, and to generate traffic statistical information including the traffic object information and intersection environment information; a digital twin generation step of inputting the traffic statistical information to a simulator, and implementing a traffic situation of the intersection as a graphical digital twin; and a composite congestion index derivation step of deriving a composite congestion index from each of an actual digital twin and a virtual digital twin, in which the evaluation indices are derived based on a congestion time of a predetermined number of vehicles at the corresponding intersection.

Method and system for calculating and comparing evaluation indices for signal system of intersection

Provided is a method and an apparatus for generating an X-ray. The method for generating an X-ray image by the apparatus includes: obtaining a first camera image of the examinee's head by the camera image obtaining processor; obtaining a first projection image by photographing a first region of the examinee's head by the X-ray photographing unit; changing a relative position between the examinee's head and the X-ray photographing unit by the driving unit; obtaining a second camera image of the examinee's head by the camera image obtaining processor; obtaining a second projection image by photographing a second region of the examinee's head by the X-ray photographing unit; and generating the X-ray image by stitching and reconstructing the first projection image and the second projection image based on the first camera image and the second camera image by the X-ray image generation unit.

Method and apparatus for generating x-ray image and computer-readable recording medium

Provided is a method for applying filters for dental CT imaging, including: acquiring the dental CT imaging using a dental CT apparatus; extracting an artifact region from the acquired image; applying a first filter to a region other than the artifact region in the acquired image; and outputting the dental CT imaging to which the filter is applied. Dental CT imaging is provided without an artifact region to assist in medical treatment. More specifically, the dental CT imaging without the artifact region around the metal or tooth is able to be provided to assist in dental treatment. Further, the dental CT imaging without a white artifact region is able to be provided at a boundary portion of field of view (FOV) to assist in dental treatment.
