Due to the factors such as lens distortion and camera misalignment, stereoscopic image pairs often contain vertical disparities. Introduced herein is a method and apparatus that determine and correct vertical disparities in stereoscopic image pairs using an optical flow map. Instead of discarding vertical motion vectors of the optical flow map, the introduced concept extracts and analyzes the vertical motion vectors from the optical flow map and vertically aligns the images using the vertical disparity determined from the vertical motion vectors. The introduced concept recognizes that although not apparent, vertical motion does exist in stereoscopic images and can be used to correct the vertical disparity in stereoscopic images.

Vertical disparity detection in stereoscopic images using a deep neural network

The present disclosure provides methods for stabilizing a colloidal dispersion during transport for low defect tolerance applications. The methods involve eliminating fluid interfaces within a dispersion, storing the dispersion in an environment of inert gas, and degassing the dispersion. Several bottle closure devices are described which may be ideal for use with these methods, being able to seal a container filled with a dispersion, permit the removal of headspace and rapidly empty the contained dispersion. In one aspect, the device includes a vented cap and semi-permeable membrane, which allows the passage of gas into and out of the container, and a dispenser nozzle integrated with the device to allow a stored dispersion to be dispensed without removing the device from the container. In another aspect, the bottle closure device includes an attachment point for a removable downtube and dispenser nozzle.

The present disclosure is directed to a method to correct for visual artifacts in a virtual reality (VR) video image where there is significant motion of the video image as a result of user actions. A user may request that the video image be moved, such as a through motion detected through a VR device, i.e., turning the head, or through a request to an application, i.e., joystick feedback to a gaming application. The video image motion can cause stutter and jitter visual artifacts, when the video frame buffer uses a synchronization constraint, such as vertical synchronization (VSync). When the VSync is disabled, a tearing visual artifact can be present. This disclosure presents a frame buffer handling process that operates with VSync disabled. The process allows the display refresh rates to operate at higher frequencies, while correcting for significant motion of the video image, i.e., tearing, through shifting back certain pixels within the scanout frame buffer.

Vertical disparity detection in stereoscopic images from optical flow data

A method for stereoscopically presenting visual content is disclosed. The method comprises identifying and distinguishing between a first type of content and a second type of content of a frame to be stereoscopically displayed. The method also comprises rendering the first type of content in a first left and a first right frame from a single perspective using a first stereoscopic rendering method. Further, the method comprises rendering the second type of content in a second left and a second right frame using a second, different stereoscopic method from two different perspectives. Additionally, the method comprises merging the first and second left frames and the first and second right frames to produce a resultant left frame and a resultant right frame. Finally, the method comprises displaying the resultant left frame and the resultant right frame for stereoscopic perception by a viewer.

The disclosure is directed to a method to compensate for visual distortion when viewing video image streams from a multiple camera capture of a scene where the method determines the disparity difference utilizing the user view orientation and then compresses and/or stretches the left and/or right eye video image streams to compensate for the visual distortion. In another aspect, the method describes additional adjustments and corrections to the video image streams including rotating, tilting, shifting, and scaling the video image streams, and correcting for gapping and clipping visual image artifacts. In another aspect, a visual compensation system is described to implement the method. Additionally, a visual compensation apparatus is disclosed to perform the method operations.
