Latest Patents

Ebrahimi's latest patents include a method and apparatus for a region-based approach to coding a sequence of digital images. This invention involves an encoder that segments frames into multiple regions of arbitrary shapes, each with a corresponding motion vector relative to a previously decoded frame. The technique employs a hierarchical multi-resolution motion estimation and segmentation method, which assigns the best motion vector to each block. The invention also includes a region interior coder that utilizes frequency domain region-zeroing and space domain region-enforcing operations for effective coding of the interior image data.

Another notable patent focuses on predictive video coding using a motion vector updating routine. This improved method employs a hierarchical approach to update motion vectors for smaller regions of a frame. The routine selects the best motion vector based on a priority scheme and predetermined threshold values, allowing for efficient encoding and transmission of contour pixels to a decoder.
