Latest Patents
One of Hiroshi Sako's latest patents involves a sophisticated camera system designed to capture facial images. This system utilizes a unit that generates a tracking signal containing feature extraction data. In conjunction with a memory store, the unit produces an output signal representing a substitute face that mirrors the features of the subject's face. The process begins with the detection of the facial area, which is crucial for accurately locating the mouth and eyes. The system employs specific components for detecting facial features, ensuring precision in tracking and representation.
Another significant patent by Sako pertains to the real-time processing of facial expressions. This invention generates output data related to the states of various facial parts. A facial area detection unit operates with monitoring and determining processing circuits that work in a pipelining manner. These circuits monitor pixel value frequency using advanced techniques such as 3D histogram and backprojection processing. The resulting facial area signal is enhanced by masks applied to the mouth and eye area detection units, which function on principles similar to the facial area detection unit.
