Latest Patents

Khalil holds a patent titled "Constrained wavelet packet for tree-structured video coders." This patent presents a method for optimizing a wavelet packet structure for subsequent tree-structured coding. The method preserves coherent spatial relationships between parent coefficients and their respective four offspring at each step. A valid frequency tree is defined by a wavelet packet decomposition algorithm. Constraints are placed on the pruning of the frequency tree to select valid frequency trees at each step. These constraints ensure that any four offspring sub-bands are considered for pruning only when their current frequency decomposition level matches that of their respective spatially co-located parent sub-band. Additionally, it addresses the pruning of spatially co-located offspring sub-bands when pruning only the parents results in an invalid wavelet packet structure.
