Video characterization for smart encoding based on perceptual quality optimization
Videos may be characterized by objective metrics that quantify video quality. Embodiments are directed to target bitrate prediction methods in which one or more objective metrics may serve as inputs into a model that predicts a mean opinion score (MOS), a measure of perceptual quality, as a function of metric values. The model may be derived by generating training data through conducting subjective tests on a set of video encodings, obtaining MOS data from the subjective tests, and correlating the MOS data with metric measurements on the training data. The MOS predictions may be extended to predict the target (encoding) bitrate that achieves a desired MOS value. The target bitrate prediction methods may be applied to segments of a video. The methods may be made computationally faster by applying temporal subsampling. The methods may also be extended for adaptive bitrate (ABR) applications by applying scaling factors to predicted bitrates at one frame size to determine predicted bitrates at different frame sizes.

Spatially adaptive video compression for multiple streams of color and depth
Techniques of compressing color video images include computing a delta quantization parameter (ΔQP) for the color images based on a similarity between the depth image surface normal and the view direction associated with a color image. For example, upon receiving a frame having an image with multiple color and depth images, a computer finds a depth image that is closest in orientation to a color image. For each pixel of that depth image, the computer generates a blend weight based on an orientation of a normal to a position of the depth image and the viewpoints from which the plurality of color images were captured. The computer then generates a value of ΔQP based on the blend weight and determines a macroblock of color image corresponding to the position, the macroblock being associated with the value of ΔQP for the pixel. |
