    Abstract: Methods of image interpolation disclosed herein include a method of irregular-grid expanded-block weighted motion compensation (IEWMC) and a method of block-wise directional hole interpolation (BDHI). The IEWMC can be used with unidirectional motion or disparity trajectories. The IEWMC can be applied in both forward and backward directions, and the interpolated images resulting from IEWMC application can be superimposed, or averaged, to reduce the blocking artifacts and handle the holes and overlaps. The BDHI takes into account the orientation of local edges and textures when filling the holes, which results in a sharper interpolated image.

    Abstract: The invention relates to a method and an apparatus for reducing blocking artifacts in block-wise coding of still and video images. A learning filter generator is provided at the image encoder for generating a set of filters and associated filtering rules for filtering cross-boundary image patterns based on representative original and decoded training images using a supervised machine learning algorithm. An adaptive filter at the image decoder receives the generated filters and associated filtering rules and performs locally adaptive filtering in accordance with the received filtering rules.

    Abstract: A curved wavelet transform and a related image/video compression system are disclosed. The curved wavelet transform (CWT) is carried out by applying one-dimensional (1-D) wavelet filters along curves, rather than along only horizontal and vertical directions. The image/video compression system includes a curve determination unit, a curved wavelet transform unit, a wavelet coefficient quantization unit, a wavelet coefficient coding unit, and a curve coding unit. The quantization and coding of the wavelet coefficients are related to the curves. In one embodiment, recursive wavelet filters are used for inverse wavelet decomposition. The system provides higher compression capability than conventional wavelet-based image compression systems.
