Title: Hiroshi Ito: Innovator in Video Processing Technologies
Introduction
Hiroshi Ito is a prominent inventor based in Fort Lee, NJ (US), known for his contributions to video processing technologies. With a total of 3 patents, he has made significant advancements in the field of feature extraction and scene change detection in compressed video sequences.
Latest Patents
Hiroshi's latest patents include innovative methods for feature extraction from MPEG-2 and MPEG-4 compressed video sequences. His first patent focuses on evaluating the spatio-temporal compression complexity of video sequences for feature extraction. This method inspects the compressed bitstream and uses the complexity as a descriptor of the spatio-temporal characteristics of the video sequence. The approach allows for effective matching criteria and absolute indexing, achieving reasonable accuracy with high simplicity, as it relies on entropy decoding rather than computationally expensive inverse Discrete Cosine Transformation (DCT).
Another notable patent addresses methods of abrupt scene change detection and fade detection for indexing video sequences. This invention applies scene change and fade-detection techniques to compressed signals, maintaining reasonable accuracy and simplicity through entropy decoding, again avoiding the need for costly inverse DCT computations.
