Latest Patents

One of his latest patents is titled "Methods and systems for detecting obstacles for a visual prosthesis." This invention discloses systems and methods for detecting and displaying obstacles to visually impaired persons. The technology analyzes images from a captured scene to identify obstacles. A V-Disparity algorithm is utilized to detect the ground plane and remove it from the images, thereby enhancing the capacity of retinal implants to display only obstacles. The system comprises cameras for image capture, a processor with memory for obstacle detection, ground plane removal, and pixel mapping, as well as a retinal implant that receives the pixel map to display obstacles through electrical stimulation of retinal nerves. The method includes synchronizing captured images and calculating a disparity map to detect obstacles and remove the ground plane from processed images. Depth information can be derived from stereo cameras, a time-of-flight camera, or a structured light camera. Another notable patent is the "Video processing unit for a visual prosthesis."
