Abstract: Speeding up small block intra-prediction in video coding is described herein. The system includes an encoder. The encoder is to execute intra-prediction by deriving a plurality of prediction angles, wherein the prediction angles are based on a video coding standard. The encoder is also to disable a prediction angle for a current block to eliminate a dependency on an immediate predecessor block.

Abstract: Example methods, apparatus, systems and articles of manufacture (e.g., physical storage media) to implement multi-plane image (MPI) compression are disclosed. Example apparatus disclosed herein include an interface to access an input multiplane image stack corresponding to a source camera viewpoint, the input multiplane image stack including a plurality of texture images and a corresponding plurality of alpha images, ones of the alpha images including pixel values representative of transparency of corresponding pixels in respective ones of the texture images. Disclosed example apparatus also include a compressed image encoder to at least one of (i) convert the plurality of texture images to a single composite texture image to generate a compressed multiplane image stack, or (ii) convert the plurality of alpha images to a single composite alpha image to generate the compressed multiplane image stack. In some disclosed examples, the interface is to output the compressed multiplane image stack.
