Embodiments of the present invention disclose techniques for outputting content aware video based on at least one a video application use case. The technique recognizes objects associated with the use case and performs enhancement of the objects based on content-aware rules, and composes at least some of the objects in an output frame based on on content-aware frame composition templates. Embodiments of the present invention also disclose systems for implementing the above techniques.

Method and system for content aware dynamic image framing

For video applications, a method for dynamically switching from a current ROI to a target ROI is disclosed, wherein the target ROI only includes active speakers. Advantageously, if the target ROI crops a non-speaker, then the target ROI is expanded to include said non-speaker. Transitioning from the current ROI to the target ROI may be achieved based on a cutover transition technique, or a smooth transition technique. The cutover transition technique achieves the change from the current arrived to the target ROI in a single interval, whereas the smooth transition technique achieves the change over a number of intervals, wherein a percentage of the total change required is allocated to each interval. A system for implementing the above method is also disclosed.

Method and system for automatic speaker framing in video applications

A system for generating real-time panoramic video is disclosed. The system comprises a plurality of micro panoramic cameras which are enabled on a processing unit and which are configured to simultaneously capture video frames from each of the plurality of micro panoramic cameras, wherein the video frames captured by two consecutive camera sensors from the plurality of camera sensors include an overlapping field of view, synchronize and feed the captured images to the processing unit with equal predefined delay, stitch the video frames captured by each of the plurality of micro panoramic cameras and output a real-time panoramic video on a display.

Panoramic camera device

A three-dimensional imaging system for generating a 3D panoramic video/image is disclosed. The three-dimensional imaging system includes a plurality of stereoscopic pairs of compound cameras which are separated by a predefined distance d. The imaging system is configured to operate in a first mode to generate panoramic images simultaneously using the compound cameras. Spatial distortion and temporal distortion are calculated for each column in a region of overlap of the field of view of the panoramic images generated. The column for which the spatial and temporal distortion is minimum is marked as a seam location. The marked seam location is changed based on location of a motion in the column for which the calculated spatial and temporal distortion is minimum.

Panoramic 3D camera

A chassis for use in a panoramic camera is disclosed. The chassis comprises a base, a heat sink which comprises a metal boss formed on a first portion of the base to dissipate heat generated by a main processor of the panoramic camera; and an isothermal mounting structure formed on a second portion of the base including a plurality of slots and apertures, wherein a plurality of imaging sensors are mounted on the isothermal mounting structure using the plurality of slots and apertures.

Camera chassis for a panoramic camera with isothermal mounting base

A panoramic video conferencing server is disclosed. The server is operational to capture an audio stream via an array of microphones. The captured audio stream is de-multiplexed to extract audio for a plurality of audio zones. A region of interest (ROI) is determined for a plurality of client devices to which a panoramic video is being streamed. The ROI is determined based on a zoom information which is inputted by any one of the client devices. A modified audio channel associated with the panoramic video being streamed to at least one of the client devices is generated for each of the client devices. The modified audio channel is adjusted to coincide with directionality of an audio corresponding to the associated region of interest (ROI) inputted by the at least one of said client device and the modified audio channel is adjusted to mute audio corresponding to the audio zones other than the audio zone associated with the ROI.

Panoramic streaming of video with user selected audio

A three dimensional imaging system for generating a 3D panoramic video/image is disclosed. The three dimensional imaging system comprising a plurality of stereoscopic pairs of compound cameras is disclosed. The pair of compound cameras being separated by a predefined distance d.

A chassis for use in a panoramic camera is disclosed. The chassis comprises a base, a heat sink which comprises a metal boss formed on a first portion of the base to dissipate heat generated by a main processor of the panoramic camera; and an isothermal mounting structure formed on a second portion of the base, wherein an isothermal mounting structure defines a plurality of mounting formations each for securing imaging sensor thereto.

Camera chassis for a panoramic camera with isotheramal mounting base

A method for processing video is disclosed. The method comprises associating a plurality of audio zones with the video; associating a region of interest (ROI) for each of a plurality of client devices to which the video is currently being streamed; for each client device generating custom video comprising a modified video channel associated with the video being streamed to that client, wherein the modified audio channel comprises an enhanced audio for at least one audio zone indicated by the region of interest (ROI) for said client device.

A system for video capture and delivery is disclosed. The system comprises a camera with multiple sensors to capture video at a first location, and to stitch images corresponding to the multiple sensors to produce a panoramic video having at least a 100 degrees field of view; and a cloud-based server to process the panoramic video for delivery to a plurality of client devices, and to stream the processed video to the plurality of client devices.

Video system for real-time panoramic video delivery

A chassis for use in a panoramic camera is disclosed. The chassis comprises a base; an a heat sink formed on a first portion of the base; and an isothermal mounting structure formed on a second portion of the base, wherein an isothermal mounting structure defines a plurality of mounting formations for securing imaging sensors thereto.
