Abstract: The invention relates to a method for encoding, a method for decoding, an apparatus, computer program products, an encoder and a decoder for video information. The motion vector for a block in a video image is predicted from a set of motion vector prediction candidates determined based on previously-coded motion vectors. A motion vector prediction candidate is included in the set based on the location of the block associated with the first spatial motion vector prediction candidate and in comparison with motion vector prediction candidates already in the set.

Abstract: A method of operating optical systems includes forming a stitched image of a field of regard using a first optical device. The stitched image of the field of regard comprises a plurality of sub-images associated with a first field of view. The method also includes receiving an image of a second field of view from a second optical device and determining a location of the image of the second field of view in the stitched image. The method further includes communicating an indicator to the second optical device. The indicator is to the location of the image of the second field of view in the stitched image.

Abstract: Systems and methods for setting up a cloud-based video surveillance system with at least one computing device and at least one video camera in a local area network. The at least one computing device has an application program installed and is operable to find out the at least one video camera on the same local area network and connect the at least one video camera to a cloud platform. The video surveillance system is accessible via the at least one computing device locally or other computing device remotely. The video surveillance system is still at work when the at least one computing device is powered off.

Abstract: The disclosure extends to methods, systems, and computer program products for digitally imaging with area limited image sensors, such as within a lumen of an endoscope. The system includes an image sensor comprising a pixel array for sensing electromagnetic radiation. The pixel array comprises a plurality of pixel groups comprising only active pixels, a plurality of pixel groups comprising only optical black pixels, and a plurality of line readouts, wherein each line readout is configured to read out a single group of the plurality of pixel groups in the pixel array. The imaging system samples one or more of the plurality of pixel groups comprising only optical black pixels a plurality of times to reduce a size of the image sensor by reducing a number of optical black columns.

Abstract: A three-dimensional (3D) display module, a 3D display system and a 3D display method are provided. The 3D display module includes a first plane mirror, a second plane mirror disposed correspondingly to the first plane mirror. A side of the first plane mirror coincides with a side of the second plane mirror to form a dihedral angle between the first plane mirror and the second plane mirror. The 3D display module also includes a first display screen and a second display screen disposed correspondingly to the first display screen. The first display screen and the second display screen are disposed outside the dihedral angle and at two sides of an angle bisecting plane of the dihedral angle, respectively. A first virtual image of the first display screen is overlapped with a second virtual image of the second display screen to form a first 3D virtual image.
