    Abstract: An apparatus and method for computed tomography image processing is provided. The apparatus includes: an X-ray detection unit that detects an X-ray beam having passed through a subject and outputs an energy value thereof; a line integral calculation unit that calculates line integral values of attenuation coefficients representing attenuation of the energy value of the X-ray beam having passed through the subject and been detected, based on the energy value; an image processing unit that reconstructs a tomogram based on the line integral values; and an image output unit that outputs the tomogram. The apparatus and method for computed tomography image processing can calculate line integral values of attenuation coefficients constituting an integrand of an X-ray projection function using the mean value theorem for integrals in order to restore an image of a subject from an X-ray beam detected in computed tomography image processing.

    Abstract: Disclosed is an image analysis system which includes a first analyzer and a second analyzer. The first analyzer generates first features by encoding images through a first model and adjusts a weight of the first model based on the first features. The second analyzer generates second features based on the first features by encoding the images through a second model, classifies the second features into classes, respectively, and adjusts a weight of the second model based on mutual information and a correlation between a first class among the classes which features corresponding to an original image group from among the second features are classified as and a second class among the classes which features corresponding to an augmentation group of the original image group from among the second features are classified as.
