Abstract: Moving objects are detected from a temporal sequence of images captured from successive viewpoints. Image flow vectors are computed from the temporal sequence of images, for example of flow between difference images derived from the sequence. An average direction of the image flow vectors associated with displacement of image areas between a first image and a second image derived from temporal sequence of images is computed. Preferably, a method of averaging is used that is designed to suppress the effect of outliers. Regions are determined in the first image. For each of the identified regions along range of positions along the computed average direction from a position of the identified region, it is determined whether or not there is a match between first image content in the identified region in the first image and second image content in a patch located within said range of positions in the second image.
