Wide-angle lens provides a broad field of view which benefits some applications, such as video surveillance or endoscopic imaging. However, it also induces lens distortion, especially radial distortion, which may impede further video analysis or perceptual interpretation. For some applications, such as minimally invasive surgery and visual surveillance, real-time correction of image distortion is required. Traditional CPU-centric machines are difficult to achieve the requirement of real-time… CONTINUE READING
