Latest Patents

One of Harapanahalli's key patents is titled "Motion estimation technique for digital video encoding applications." This invention provides an improved motion estimation encoder that receives a raw image in the form of a current frame and estimates the macroblock motion vector with respect to a reference frame. The encoder performs an initial local search around an initial motion vector candidate derived from spatio-temporal neighboring macroblock parameters. It compares the user-defined complexity scalable sum of absolute difference between the original and the associated reference macroblock against an adaptive threshold value for motion estimation convergence. In cases where the initial local search fails, the encoder introduces a global full search around a candidate from a coarser level. The encoder selects an inter encoding mode for coding the current macroblock when the first local search is successful; otherwise, it selects the inter or intra encoding mode by comparing variances of the original and difference macroblocks. This patent highlights Harapanahalli's innovative approach to improving digital video encoding processes.
