A parallax correction method for a transparent display system is provided. The transparent display system includes a transparent display device located between a background object and a user. The parallax correction method includes the following steps. A gaze point is displayed on the transparent display device. An image including the transparent display device, the background object and the user is captured. At least two display anchor points and at least two corresponding background object anchor points are detected according to the image. The display anchor points are located on the transparent display device, and the background object anchor points are located on the background object. A plurality of visual extension lines extending from the display anchor points and the corresponding background object anchor points are obtained. An equivalent eye position of the ocular dominance of the user is obtained according an intersection of the visual extension lines.

Saliency regions are identified in a global scene depicted by volumetric video. Saliency video streams that track the saliency regions are generated. Each saliency video stream tracks a respective saliency region. A saliency stream based representation of the volumetric video is generated to include the saliency video streams. The saliency stream based representation of the volumetric video is transmitted to a video streaming client.

A system includes a robotic arm, an autosteroscopic display, a user image capture device, an image processor, and a controller. The robotic arm is coupled to a patient image capture device. The autostereoscopic display is configured to display an image of a surgical site obtained from the patient image capture device. The image processor is configured to identify a location of at least part of a user in an image obtained from the user image capture device. The controller is configured to, in a first mode, adjust a three dimensional aspect of the image displayed on autostereoscopic display based on the identified location, and, in a second mode, move the robotic arm or instrument based on a relationship between the identified location and the surgical site image.

An imaging system including: first camera and second camera; depth-mapping means; gaze-tracking means; and processor configured to: generate depth map of real-world scene; determine gaze directions of first eye and second eye; identify line of sight and conical region of interest; determine optical depths of first object and second object present in conical region; determine one of first camera and second camera having lesser occlusion in real-world scene; adjust optical focus of one of first camera and second camera to focus on one of first object and second object having greater optical depth, and adjust optical focus of another of first camera and second camera to focus on another of first object and second object; and capture first image(s) and second image(s) using adjusted optical focuses of cameras.

While a viewer is viewing a first stereoscopic image comprising a first left image and a first right image, a left vergence angle of a left eye of a viewer and a right vergence angle of a right eye of the viewer are determined. A virtual object depth is determined based at least in part on (i) the left vergence angle of the left eye of the viewer and (ii) the right vergence angle of the right eye of the viewer. A second stereoscopic image comprising a second left image and a second right image for the viewer is rendered on one or more image displays. The second stereoscopic image is subsequent to the first stereoscopic image. The second stereoscopic image is projected from the one or more image displays to a virtual object plane at the virtual object depth.
