  • Determination of image shapes using training and sectoring
    Patent number: 6111983
    Abstract: For enhanced accuracy in determining a shape in an image, a shape model can be trained for parameter settings, based on training data for which the desired shape is specified. Such training can be applied to models in which a shape is treated in a sectored fashion, with training applied to each of the sectors. The suitability of an objective function, obtained by training or otherwise, can be assessed by using near-correct shapes which are generated by randomly perturbing a ground-truth shape.
