Systems, methods, apparatuses, and computer program products for displaying an image. A method may include generating an image from a tuned light pattern directly through a nanophotonics phased-array chip. The method may also include applying a proximity effect on the image. The method may further include adjusting an image quality of the image by performing proximity effect correction on the image with the proximity effect. In addition, the method may include controlling a phase of an optical signal emanating from the nanophotonics phased-array chip. Further, the method may include projecting the adjusted image based on the controlled phase of the optical signal.

Systems, methods, apparatuses, and computer program products for creating freely explorable, dynamic and photorealistic virtual environments, reconstructing view dependent holograms in real-time, and inserting 3D virtual objects into 360 camera based navigable environment. A method, may include simultaneously capturing 360 video data and audio data from a plurality of viewpoints within a real-world environment. The method may also include preprocessing and compressing the 360 video data and the audio data into a three-dimensional representation suitable for display. The method may further include rendering a virtual environment of the real-world environment. In addition, the method may include creating a blended virtual environment by combining the captured 360 video data and the audio data with the rendered virtual environment. Further, the method may include displaying the blended virtual environment in a display apparatus of a user.

Disclosed are systems, devices, and methods for creating a rendering of real-world locations with embedded multimedia elements. An exemplary method includes receiving image data of a real-world location, identifying geographic coordinates of the real-world location and/or a point of view from which the image data was acquired, acquiring multimedia elements relevant to the real-world location based on the geographic coordinates and/or the point of view, and creating a rendering of the image data with the multimedia elements embedded therein.

Systems, devices, and methods for generating a social street view

A method, system and apparatus for determining and modifying saliency of a visual medium are provided. The method, system and apparatus may obtain saliency values for a visual medium based on a plurality of visual channels. The saliency values may be obtained based on at least one of computer-generated modeling, user-specified input and eye-tracking. The method, system and apparatus may aggregate the obtained saliency values and classify regions of the visual medium based on the aggregated saliency values. The visual channels may include one or more of absolute mean curvature, a gradient of mean curvature, a gradient of color intensity, color luminance, color opponency, color saturation, lighting and focus. When calculating mean curvature, the method, system and apparatus may calculate a change in mean curvature for a plurality of vertices around a region and displace the vertices in accordance with the calculated change in mean curvature to change a saliency of the region.

A multifunctional interaction system which is capable of spatio-temporal context localization of users and of communication of audio/video streams to an entity of interest defined by the user, includes a communication domain supporting a predefined localization service, a server associated with the communication domain, client devices, and a dynamically changing context database which is customized in accord with the dynamics of interaction sessions of client devices with the server. The client communicates with the system to either request services therefrom or to send a message to the entity of interest. The system is provided with a panic alert mechanism which, upon actuation, transmits an audio/video data stream along with the client location tag, time stamp, and client ID, to a police precinct for prompt action.
