Abstract (en)
[origin: WO2015131304A1] A method and device are provided for encoding and/or decoding video and/or image content using dictionary modes. For example, the method and device predict current pixel values from previous pixel values stored in a 1-D dictionary. The method and device predict current pixel values from previous pixel values using a pseudo 2-D dictionary mode. Yet the method and device predict current pixel values using a pseudo 2-D dictionary mode. Yet the method and device predict current pixel values from previous pixel values in a reference picture using an inter pseudo 2-D dictionary mode. Pixel values can be predicted from previous pixel values (e.g., stored in a dictionary) that are identified by an offset and a length. Yet the method and device encode pixel values using hash matching of pixel values.
