  • Method for detecting a moving object in a sequence of images captured by a moving camera, computer system and computer program product
    Patent number: 8629908
    Abstract: The invention relates to a method for detecting a moving object in a sequence of images captured by a moving camera. The method comprises the step of constructing a multiple number of difference images by subtracting image values in corresponding pixels of multiple pairs of images being based on captured images. Further, the method comprises the step of retrieving a moving object by extracting spatial information of pixels in the multiple number of constructed difference images having relatively large image values. In addition, from a pair of images in the construction step an image is a representation of a high resolution image having a higher spatial resolution than original captured images on which the high resolution image is based.
