Abstract: This disclosure describes methods and apparatus for decoding data. In one aspect, the method comprises decoding encoded video data to obtain decoded video frame data, the encoded video data comprising encoded video frame data encoded at a first frame rate and embedded data. The method further comprises determining a camera parameter from the embedded data and up-converting the decoded video frame data to a second frame rate based on the camera parameter. The determined camera parameter may be, for example, a parameter associated with one or more of a zoom factor, an auto focus status, lens position information, frame luma information, an auto exposure (AE) convergence status, an automatic white balance (AWB) convergence status, global motion information, and frame blurriness information, and the like. An encoding device may embed the camera parameter(s) in an encoded video bit stream for a decoder to utilize during frame rate up-conversion.

Abstract: The disclosure is directed to techniques for encoder-assisted adaptive interpolation of video frames. According to the disclosed techniques, an encoder generates information to assist a decoder in interpolation of a skipped video frame, i.e., an S frame. The information permits the decoder to reduce visual artifacts in the interpolated frame and thereby achieve improved visual quality. The information may include interpolation equation labels that identify selected interpolation equations to be used by the decoder for individual video blocks. As an option, to conserve bandwidth, the equation labels may be transmitted for only selected video blocks that meet a criterion for encoder-assisted interpolation. Other video blocks without equation labels may be interpolated according to a default interpolation technique.
Abstract translation: 本公开涉及视频帧的编码器辅助自适应插值技术。 根据所公开的技术，编码器生成信息以帮助解码器插入跳过的视频帧，即S帧。 该信息允许解码器减少内插帧中的视觉伪影，从而实现改善的视觉质量。 该信息可以包括识别用于各个视频块的由解码器使用的所选内插方程的内插方程标签。 作为选择，为了节省带宽，可以仅针对满足编码器辅助插值的准则的所选择的视频块来发送等式标签。 没有等式标签的其他视频块可以根据默认内插技术进行内插。

Abstract: Certain embodiments relate to systems and methods for presenting an autostereoscopic, 3-dimensional image to a user. The system may comprise a view rendering module to generate multi-view autostereoscopic images from a limited number of reference views, enabling users to view the content from different angles without the need of glasses. Some embodiments may employ two or more reference views to generate virtual reference views and provide high quality stereoscopic images. Certain embodiments may use a combination of disparity-based depth map processing, view interpolation and smart blending of virtual views, artifact reduction, depth cluster guided hole filling, and post-processing of synthesized views.

Abstract: Methods, systems, and apparatuses are provided to automatically detect objects within images. For example, an image capture device may capture an image, and may apply a trained neural network to the image to generate an object value and a class value for each of a plurality of portions of the image. Further, the image capture device may determine, for each of the plurality of image portions, a confidence value based on the object value and the class value corresponding to each image portion. The image capture device may also detect an object within at least one image portion based on the confidence values. Further, the image capture device may output a bounding box corresponding to the at least one image portion. The bounding box defines an area of the image that includes one or more objects.
