Usually, moving shadow regions lead to larger regions for detected objects. Shadow pixels have almost the same chromaticity as the original background pixels but they only have lower brightness values. Shadow regions usually retain the underlying texture, surface pattern, and color value. Therefore, a shadow pixel can be represented as a.x where x is the actual background color vector in 3-D RGB color space and a is a positive real number less than 1. In this paper, a shadow detection method based on two-dimensional (2-D) cepstrum is proposed. © 2009 SPIE.English2-D CepstrumShadow detection in video2-D CepstrumBackground pixelsBrightness valuesCepstrumColor valuesColor vectorMoving object detection and trackingPositive realRGB color spaceShadow detection in videoShadow detectionsShadow regionsSurface patternColorNumber theoryPixelsTwo dimensionalConference Paper10.1117/12.819053
