An image display apparatus includes a display unit having a screen that displays an image, an image generation unit that generates an image to be displayed on the screen, a Fresnel lens disposed at a predetermined distance from the screen, a specular-reflection preventing device that causes a rear surface of the Fresnel lens to move so as to be tilted at an angle at which incident light from a user side where a user sees the image is not specularly reflected to the user side, and an image correction unit that corrects image distortion caused by the specular-reflection preventing device.

A method includes obtaining a fisheye image of a scene and identifying multiple regions of interest in the fisheye image. The method also includes applying one or more transformations to transform and rotate one or more of the regions of interest in the fisheye image to produce one or more transformed regions. The method further includes generating a collage image having at least one portion based on the fisheye image and one or more portions containing the one or more transformed regions. In addition, the method includes performing object detection to identify one or more objects captured in the collage image.

Embodiments described herein provide an integrated holographic reconstruction platform that enables a user to perform three-dimensional visualization of a phenomenon by reconstructing holograms using a combination of normalization and propagation algorithms, which yields better results with significantly less demanding processing time and computing resources. Specifically, the integrated holographic reconstruction platform may be implemented as an all-in-one computer software that includes software components of digital holographic reconstruction, de-twining and optical distortion removal via a user-friendly graphical interface.

A method for correcting a geometric distortion in a diagnostic image, said method comprising the steps of: receiving a segmented volumetric image and a surface scan image, corresponding to a maxillofacial anatomy of a patient; aligning the surface scan mesh to a volumetric image; and applying a transformation to the surface scan image mesh in which the geometry of a HV-LD is altered yielding the surface scan image mesh with tooth crowns closely corresponding to the volumetric image teeth image resulting in a correction for the geometric distortion.

When a first user makes a video call with a second user of the other side by using the video call function, a first state is set as a state in which the enclosure is flatly placed on a first surface of an object, and in which a face of the first user is included within a range of an angle of view AV1 of the front camera C1. In the first state, the mobile information terminal 1 detects a first region including the face of the first user from a wide angle image that is captured by the front camera C1, trims a first image corresponding to the first region, creates a transmission image to be transmitted to a terminal of the other side on the basis of the first image, and transmits the transmission image to the terminal of the other side.

The present disclosure relates to a medical observation system, an image processing method, and a program capable of providing image display more helpful for a surgeon. A correction processing unit performs correction processing on a wide-angle image which is a captured image of a medical treatment target, a clipping processing unit moves a clipping area for a display image clipped from the wide-angle image, and a correction control unit controls the correction processing according to a relative state of the clipping area to the wide-angle image. The present disclosure can be applied to, for example, an endoscopic surgery system.

An example apparatus for adjusting eye gaze in images one or more processors to execute instructions to bidirectionally train a neural network; access a target angle and an input image, the input image including an eye in a first position; generate a vector field with the neural network; and generate a gaze-adjusted image based on the vector field, the gaze-adjusted image including the eye in a second position.

A computer-implemented method executed by at least one processor for reducing radial distortion errors in fish-eye images is presented. The method includes capturing an image from a camera including distortions, detecting arc-shaped edge segments in the image including the distortions, estimating a main distortion parameter by fixing a distortion centerpoint in a middle of the image, estimating the distortion centerpoint with the main distortion parameter, and obtaining an undistorted version of the captured image by inverting the distortion model.

According to an embodiment of the disclosure, an electronic device may include: a display, a memory, and a processor operatively connected to the display and the memory.
