An image labelling system (10) processes an acquired image and processes the image to provide 1 bit pixels. The connectivity of each pixel is examined by decision-making apparatus (18) and labels associated with each pixel supplied by a labeller (20). The labels are determined by the labels previously applied to the pixels connected to that being labelled. The labeller (20) sends equivalence messages to processor (17) when a pixel has connecting pixels with different labels and assigns to the pixel the smallest label of that of its neighbours. A global labeller (38) is arranged to re-label the image so that each connecting pixel in one object in the image has the same label. |
