摘要：
A template useful in registering an incoming bitmapped image with a master bitmapped image is created by convolving the master with a Gaussian function and computing the gradient of the resulting scalar field. According to the invention, the incoming image is iteratively moved with respect to the template in response to the gradient of the scalar field formed by the convolution operation, i.e., the direction of adjustment is a function of the gradient of the scalar field formed by the convolution operation used to create the template. According to one embodiment of the invention, the registration process is terminated when the error between the master and the image is below a predefined threshold.
