The present disclosure relates to a magnetic particle imaging device having a field of view (FOV) wide enough to be applicable to the human body. A magnetic particle imaging device according to some embodiments includes at least: an FFP generation unit generating a field free point (FFP) in a FOV; first to third operation coil units moving the FFP in first to third directions which are vertical to each other, respectively; an excitation coil unit generating a magnetic field in the FOV, and exciting a magnetic particle in the FOV; a reception coil unit receiving a magnetic signal generated from the magnetic particle; and a processor dividing the FOV into a plurality of partial FOVs, controlling the first to third operation coil units so that the FFP moves in each partial FOV, and generating an image for the FOV based on the magnetic signal for each partial FOV.

The present invention relates to a method for creating a neural network model which can imitate retouching styles of a plurality of experts, and creating a black-and-white photo which gives aesthetics by inputting a color photo into the neural network model.

The present disclosure relates to a method of inferring an epipolar plane image and extrapolating a view of a target image using the epipolar plane image. A view extrapolation method using an epipolar plane image according to an embodiment of the present disclosure includes: creating an Epipolar Plane Image (EPI) using a target image and a depth map corresponding to the target image; creating a super-resolution EPI and a disparity of the EPI on the basis of the EPI; creating an EPI mask by warping the super-resolution EPI in accordance with the disparity; and creating a restored EPI by applying the EPI mask to the warped super-resolution EPI, and creating an extrapolated image for the target image using the restored EPI.

The present disclosure relates to a bipolar optical synaptic device, and more specifically, to a bipolar optical synaptic device capable of operating solely by a light signal.

The present disclosure relates to an OPA-based optical scanner system using a metalens, which includes an optical phased array antenna configured to modulate a phase of light input from a light source unit and output the light, and an optical unit installed on a path of light output from the optical phased array antenna and configured to focus or diffuse light output from the optical phased array antenna using a metalens.

The present disclosure relates to a secure transmitting and receiving method that crates a dynamic key on the basis of the features of real-time data, thereby performing authentication operation. A secure transmitting method for real time data according to an embodiment of the present disclosure includes: collecting an n-th datum; compressing the n-th datum; creating and storing an n-th dynamic key in a memory on the basis of a feature extracted in the compressing; creating an n-th security key using an n-m-th dynamic key stored in the memory and transmitting the n-th security key to a server; and transmitting the compressed n-th datum to the server when receiving an authentication success signal from the server.

The present disclosure relates to a virus detection method that detects whether viruses are arranged in multiple layers and the density of viruses using a color change of a virus detector. A virus detection method according to an embodiment of the present disclosure includes: taking an image of a virus detector reacting with a target analysis object; and determining whether viruses are arranged in multiple layers and density of the viruses in the target analysis object in accordance with a saturation value of the image.

The present disclosure relates to a herringbone-type fluid guiding unit and an apparatus for concentrating fluid using same. The herring-bone type fluid guiding unit includes: a front member formed on a flow path and formed so that the width between the left side and the right side widens from a front end part toward the back, with respect to the flow direction of a fluid; and a rear member extending from the front member toward the back, wherein the rear member is provided with a recessed part that is recessed to a specific depth from the rear edge toward the front or with a protruding part that protrudes toward the back.
