Abstract: Provided are medical imaging apparatuses that comprising an optical connector, a coupler configured to releasably couple to a first portion of the optical connector and a camera configured to releasably couple to a second portion of the optical connector, wherein the coupler comprises a first portion to which light is incident from the optical connector, and a second portion in which the light passes through an inside of the coupler and is emitted, wherein the first portion is tilted with a predetermined angle with respect to the second portion.

Abstract: Provided is an apparatus for generating a biometric image comprising a processor; and a memory comprising one or more sequences of instructions which, when executed by the processor, causes steps to be performed comprising: receiving a first biometric image and a second biometric image paired with the first biometric image; and generating a first reconstruction biometric image from the first biometric image so as to match the first reconstruction biometric image and the second biometric image based on a machine learning model.
