IMAGE PROCESSING

摘要

Apparatus and method for processing a sequence of images of a scene, the method comprising: tracking a region of interest (14) in the sequence of images (e.g. using a Self Adaptive Discriminant filter); selecting a particular image (12) in the sequence; selecting a set of images from the sequence,the set comprising one or more images that precede the particular image (12)in the sequence of images; for each pixel in the region of interest (14) in the particular image (12), determining a value for a parameter; for each pixel in the region of interest (14) of each image in the set of images, determining a value for the parameters; and comparing a function of the determined values for the region of interest (14) in the particular image to a further function of the determined values for the regions of interest (14) in the images in the set of images.
