Abstract: A background image is also generated, e.g., by filling portions of a captured image where a foreground object was extracted and communicated to the playback device, Foreground objects are identified and point cloud representations of the foreground objects are generated and communicated to a playback device so that they can be used in generating images including the background which is communicated separately. In the case of a point cloud representation a number of points in an environment, e.g., 3D space, are communicated to the playback device along with color information. Thus in some embodiments a foreground object is represented as a set of points with corresponding color information on a per point basis. Foreground object information is communicated and processed in some embodiments at a different rate, e.g., faster rate, then the background textures.

Abstract: Methods and apparatus for capturing, communicating and using image data to support virtual reality experiences are described. Images, e.g., frames, are captured at a high resolution but lower frame rate than is used for playback. Interpolation is applied to captured frames to generate interpolated frames. Captured frames, along with interpolated frame information, are communicated to the playback device. The combination of captured and interpolated frames correspond to a second frame playback rate which is higher than the image capture rate. Cameras operate at a high image resolution but slower frame rate than images could be captured with the same cameras at a lower resolution. Interpolation is performed prior to delivery to the user device with segments to be interpolated being selected based on motion and/or lens FOV information. A relatively small amount of interpolated frame data is communicated compared to captured frame data for efficient bandwidth use.

Abstract: Methods and apparatus for implementing a playback system capable of operating as a virtual or augmented reality device are described. In various embodiment one or more environmental triggers are detected and an action is taken based on the detected trigger, user input and/or other environmental conditions. The methods allow a user who is subject to an immersive experience to smoothly transition in/or out of the virtual environment and respond to environmental triggers which may require a user to take an action.

Abstract: A method and system for encoding a stereoscopic image pair is disclosed. Groups of pixels are analyzed to determine the depth of each pixel group. The number of bits per pixel used to encode each pixel group is selected based on the depth of that pixel group. Therefore, images of objects closer to the camera pair, which appear closer to the viewer, are encoded with a larger number of bits per pixel than objects perceived to be farther from the viewer. The number of bits per pixel may also be increased based on a number of objects depicted or motion detected. The size of prediction blocks used to encode image portions may also be determined based on an angular distance of an image portion relative to the center of the frame. Therefore, smaller prediction blocks may be used to encode image portions closer to the center of the frame.

Abstract: Methods and apparatus for using selective resolution reduction on images to be transmitted and/or used by a playback device are described. Prior to transmission one or more images of an environment are captured. Based on image content, motion detection and/or user input a resolution reduction operation is selected and performed. The reduced resolution image is communicated to a playback device along with information indicating a UV map corresponding to the selected resolution allocation that should be used by the playback device for rendering the communicated image. By changing the resolution allocation used and which UV map is used by the playback device different resolution allocations can be made with respect to different portions of the environment while allowing the number of pixels in transmitted images to remain constant. The playback device renders the individual images with the UV map corresponding to the resolution allocation used to generate the individual images.

Abstract: Methods for capturing and generating information about objects in a 3D environment that can be used to support augmented reality or virtual reality playback operations in a data efficient manner are described. In various embodiments one or more frames including foreground objects are generated and transmitted with corresponding information that can be used to determine the location where the foreground objects are to be positioned relative to a background for one or more frame times are described. Data efficiency is achieved by specifying different locations for a foreground object for different frame times avoiding in some embodiments the need to transmit an image and depth information defining the same of the foreground for each frame time. The frames can be encoded using a video encoder even though some of the information communicated are not pixel values but alpha blending values, object position information, mesh distortion information, etc.

Abstract: Methods and apparatus for receiving content including images of surfaces of an environment visible from a default viewing position and images of surfaces not visible from the default viewing position, e.g., occluded surfaces, are described. Occluded and non-occluded image portions are received in content streams that can be in a variety of stream formats. In one stream format non-occluded image content is packed into a frame with occluded image content with the occluded image content normally occupying a small portion of the frame. In other embodiments occluded image portions are received in an auxiliary data stream which is multiplexed with a data stream providing frames of non-occluded image content. UV maps which are used to map received image content to segments of an environmental model are also supplied with the UV maps corresponding to the format of the frames which are used to provide the images that serve as textures.

Abstract: A toilet cleaning apparatus is disclosed comprising a toilet brush head; a toilet brush handle (2) separated from the brush head by a brush shaft (1); a portion of the brush handle being adapted to contain a cleaning fluid and being in fluid communication with the brush head by a conduit (4); the handle being adapted to be reciprocally displaced along the conduit between a first position remote from the brush head and a second position proximate to the brush head so urging cleaning fluid from the handle to the brush head; and a non-return valve within the conduit (40) adapted to allow the flow of fluid from handle to brush but to prevent the flow of fluid from brush to handle. The non-return valve (40) comprises a ducks beak check valve.
