Latest Patents
One of Masato Shima's latest patents is titled "Fast macroblock structure decision using SAD discrepancy and its prediction mode." This invention presents a method to accelerate frame and field decision-making by estimating a more suitable structure using the sum of absolute differences (SAD) between picture samples and their mean. The invention utilizes the correlation observed between optimal macroblock prediction modes and the probability of non-inferred structures being better than inferred ones. This innovation can lead to a significant reduction in computational complexity, albeit with a slight degradation in coding efficiency.
Another notable patent is "Low complexity event detection for video programs." This method involves detecting significant events from video programs by computing short-time sub-band energies in audio across multiple audio sub-bands. It includes detecting scene boundaries where the weighted sum of these energies falls below a certain threshold for a specified time interval. The video program is then segmented into scenes based on these boundaries, with shorter scenes removed. The remaining scenes are classified and ranked by audio, enhancing the overall video processing capabilities.
