  • IMAGE PROCESSING OF VIDEO USING NOISE ESTIMATE
    Publication number: 20130136376
    Abstract: A method of processing image date representing an image of a scene to generate an estimate of noise present in the image data. The method comprises evaluating a function for different values of the estimate, the function taking as input an estimate of the noise, and determining an estimate of the noise for which the function has an optimum value.

  • Image processing using function optimization to estimate image noise
    Patent number: 8391632
    Abstract: A method of processing image data representing an image of a scene to generate an estimate of noise present in the image data. The method comprises evaluating a function for different values of said estimate, said function taking as input an estimate of said noise, and determining an estimate of said noise for which said function has an optimum value.

  • RETROREFLECTOR
    Publication number: 20090303592
    Abstract: Compensation for spherical aberration in retroreflectors to improve the retroreflector performance. A retroreflector has at least two concentric spherical layers. A first of the layers is of uniform refractive index n! surrounding a second of the layers of uniform refractive index n2. The refractive indices satisfy the criteria n1>n2. A retroreflector is formed as a sphere having a predetermined refractive index and radius, such that spherical aberration of incident radiation is at least partially compensated for by primary defocus.
