Title: The Innovations of Ka-Ming Leung
Introduction
Ka-Ming Leung is a prominent inventor based in Marsfield, Australia. He has made significant contributions to the field of video encoding and augmented reality systems. With a total of seven patents to his name, Leung's work showcases his expertise and innovative spirit.
Latest Patents
One of Leung's latest patents is related to Wyner Ziv coding. This system is designed for encoding an input video frame, facilitating the transmission or storage of the encoded video, and decoding the video. The system comprises an encoder and a decoder interconnected through a storage or transmission medium. The encoder utilizes a turbo encoder to generate parity bit data from the input frame, creating a first data source. Additionally, a sampler down-samples the input frame followed by intraframe compression to form a second data source. The decoder receives data from the second data source to estimate the frame and corrects errors using the parity bit data. This innovative approach enhances the reliability of video decoding.
Another notable patent is focused on key-frame selection for parallel tracking and mapping in augmented reality systems. This method involves selecting a first image from multiple images to construct a coordinate system. It determines a first image feature corresponding to a marker and matches it with a second image feature based on the camera's pose. The reconstructed position of the marker's feature in three-dimensional space is calculated, allowing for accurate augmented reality experiences.
