A method for automated routing of pictures taken on mobile electronic devices to a digital picture frame including a camera integrated with the frame, and a network connection module allowing the frame for direct contact and upload of photos from electronic devices or from photo collections of community members. The integrated camera is used to automatically determine an identity of a frame viewer and can capture gesture-based feedback. The displayed photos are automatically shown and/or changed according to the detected viewers. The photos can be filtered and cropped at the receiver side. Clustering photos by content is used to improve display and to respond to photo viewer desires.

The present disclosure provides a system for providing an image-segmentation based streaming service. The system includes a communication circuit configured to establish a communication channel with a streaming server, a storage configured to store data provided by the streaming server, a display configured to output an image, a processor functionally connected to the communication circuit, the storage, and the display. The processor can detect a region-of-interest (ROI) of an output image associated with a media presentation description (MPD) provided by the streaming server and transmit the ROI information to the streaming server. The processor can also receive image segments of a first resolution corresponding to the ROI information and a full image of a second resolution from the streaming server. The processor can also synthesize the image segments of the first resolution and the full image of the second resolution to output a synthesized reconstruction image through the display.

Systems, methods, and computer-readable storage media for calculating scaling ratios are described. An example method can include obtaining a current picture of video data and one or more scaling windows associated with the current picture and/or a reference picture selected for use in coding the current picture; determining a first size of the current picture and/or a second size of the reference picture, the first size including a first height and a first width and the second size including a second height and a second width; based on the one or more scaling windows and the first size and/or the second size, determining one or more scaling ratios associated with the current picture and/or the reference picture.

A camera system captures an image in a source aspect ratio and applies a transformation to the input image to scale and warp the input image to generate an output image having a target aspect ratio different than the source aspect ratio. The output image has the same field of view as the input image, maintains image resolution, and limits distortion to levels that do not substantially affect the viewing experience. In one embodiment, the output image is non-linearly warped relative to the input image such that a distortion in the output image relative to the input image is greater in a corner region of the output image than a center region of the output image.

Embodiments of the present invention are directed towards reframing videos from one aspect ratio to another aspect ratio while maintaining visibility of regions of interest. A set of regions of interest are determined in frames in a video with a first aspect ratio. The set of regions of interest can be used to estimate an initial camera path. An optimal camera path is determined by leveraging the identified regions of interest using the initial camera path. Sub crops with a second aspect ratio different from the first aspect ratio of the video are identified. The sub crops are placed as designated using the optimal camera path to generate a cropped video with the second aspect ratio.

Systems and methods for encoding a plurality of alternative streams of video content using multiple encoders in accordance with embodiments of the invention are disclosed. An encoding system includes multiple encoders. Each of the encoders receives a source stream of video content that is divided into portions. Each of the encoders generates portions of the plurality of alternative streams from the portions of the source stream. The portions of the alternative streams generated by a particular encoder are stored in a container for the particular encoder. Each encoder also generates index information for the portion of the alternative stream generated by the encoder that is stored in a manifest for the encoder.

A picture frame and methods of setup, gifting, and/or use. Network connection allows digital frames to be set up remotely by a first user for a second user. The first user can upload photos from electronic devices or from photo collections of community members before the second user receives the frame device. The frame is thus ready for display upon powering on by the second user. An integrated camera is used to automatically determine an identity of a frame viewer and can capture gesture-based feedback. The displayed photos are automatically shown and/or changed according to the detected viewers. The photos can be filtered and cropped at the receiver side. Clustering photos by content is used to improve display and to respond to photo viewer desires.

Disclosed are a method for displaying projection picture and a method for rotating projection picture, comprising following steps: A: using a main control chip of a display to receive a picture signal parameter of a handheld terminal; B: the main control chip determining the black edge and calculating the starting position of a display picture by detecting the intensity of display signal inputted from the handheld terminal; C: obtaining the width of the display picture by calculation, and at the same time, directly obtaining the height of the display signal by signal detection of the main control chip; and D: using the function calculation provided by a control unit to enlarge the picture to a proportional or full-screen output with the handheld terminal. After adopting the above method, the display provides a picture with full screen without having black edges or small black edges to enhance the visual experience.

The disclosed computer-implemented method may include receiving, as an input, segmented video scenes, where each video scene includes a specified length of video content. The method may further include scanning the video scenes to identify objects within the video scene and also determining a relative importance value for the identified objects. The relative importance value may include an indication of which objects are to be included in a cropped version of the video scene. The method may also include generating a video crop that is to be applied to the video scene such that the resulting cropped version of the video scene includes those identified objects that are to be included based on the relative importance value. The method may also include applying the generated video crop to the video scene to produce the cropped version of the video scene. Various other methods, systems, and computer-readable media are also disclosed.

Provided is a method and system for reducing a transmission time of a media file through concurrent processing of encoding and uploading. A media file transmission method relates to transcoding a media file at a client and uploading the transcoded media file to a server, and performs transcoding by splitting the media file based on a unit size, and here, concurrently processes transcoding of a subsequent split unit file and uploading of a previous split unit file at a point in time at which transcoding of the previous split unit file is completed.
