Latest Patents

Hwang's latest patents include an image-based hand detection apparatus and method. This innovative apparatus features a hand image detection unit that identifies a hand image corresponding to a clenched fist from an input image. It also includes a feature point extraction unit that extracts points from areas of lower brightness in the detected hand image. Additionally, an image rotation unit compares these feature points with those stored in a hand image storage unit, allowing for the rotation of the detected or stored hand images. A matching unit then compares the detected hand image with stored images, generating a comparison result. If a match is found, a hand shape recognition unit selects the matching hand image.

Another notable patent is a system and method for transmitting and receiving wideband speech signals with a synthesized signal. This system includes an A/D converter that converts an analog speech signal into a digital format. It encodes the difference between a baseband speech signal and a synthesized standard baseband signal. Furthermore, an IP network interface multiplexes the coded standard and additional baseband signals, enhancing the residual band signal.
