Title: Innovations by Xiangdong Wang
Introduction
Xiangdong Wang is an accomplished inventor based in North Billerica, MA, with a notable portfolio of five patents. His work primarily focuses on advancements in video conferencing technology, utilizing machine learning and intelligent systems to enhance user experience.
Latest Patents
One of his latest patents is titled "Intelligent multi-camera switching with machine learning." This invention involves multiple cameras in a conference room, each directed at different angles, along with a microphone array for sound source localization (SSL). The SSL technology works in conjunction with video images to identify the speaker among multiple individuals present. By employing neural network or machine learning processing, the system assesses the quality of the speaker's facial view and selects the best angle for transmission. If no satisfactory view is available, a default view is provided. This innovative approach ensures that only the speaker's head is analyzed for optimal framing during video calls.
Another significant patent is the "People detection method for auto-framing and tracking in a video conference." This invention coordinates a stationary view from a web camera with an adjustable view from a pan-tilt-zoom camera. The system detects participants by establishing a static perimeter around them, ensuring that any motion is monitored. If no motion is detected, the system identifies personage objects such as heads or faces within the perimeter, allowing for accurate tracking and framing of participants during video conferences.
