Abstract: An environmental capture system (ECS) captures image data and depth information in a 360-degree scene. The captured image data and depth information can be used to generate a 360-degree scene. The ECS comprises a frame, a drive train mounted to the frame, and an image capture device coupled to the drive train to capture, while pointed in a first direction, a plurality of images at different exposures in a first field of view (FOV) of the 360-degree scene. The ECS further comprises a depth information capture device coupled to the drive train. The depth information capture device and the image capture device are rotated by the drive train about a first, substantially vertical, axis from the first direction to a second direction. The depth information capture device, while being rotated from the first direction to the second direction, captures depth information for a first portion of the 360-degree scene.

Abstract: Systems and methods for visualizing fluid flows in a virtual reality (VR) environment are disclosed. A digital volume image representing a reservoir formation sample is obtained from an imaging device. The digital volume is segmented by assigning hydraulic properties of the formation sample to each volume element based on image properties associated with that volume element. Fluid flow is simulated using the segmented digital volume. A vector field representing flow properties at different points along one or more flow lines through the pore space is generated. An interactive visualization of a three-dimensional (3D) virtual environment representing the formation sample with the flow line(s) is provided via a VR display. Responsive to receiving user input specifying an area of the environment to view at a selected level of detail, the specified area is rendered at the selected level of detail and a current view of the interactive visualization is updated accordingly.

Abstract: Video cyclic sexual movement detection and synchronisation apparatus (10) includes a selector (12), an analyser (14) and a output generator (16). In use, the apparatus (10) receives an input signal (18) which comprises a sequence (94) of video frames (20), each frame (20) comprising a plurality of image areas (22). In a selection phase, the selector (12) selects one of the image areas (22) as a subject area (24) and another of the image areas (22) as a reference area 26. In an analysis phase, the analyser (14) analyses a set (28) of the video frames (20) to determine a subject speed parameter (30) which relates to the speed of movement of the subject area (24) relative to the reference area (26). In a synchronisation phase, the output generator (16) generates an output signal (38) which comprises a speed signal (40) which is dependent on the subject speed parameter (30).
