An image data registration system and method of storing a first data set of three-dimensional image data associated with a predetermined portion of an object with reference to a first coordinate frame; obtaining and storing a second data set of three-dimensional image data associated with a surface of the predetermined portion of the object with reference to a second coordinate frame; obtaining and storing a third data set of three-dimensional image data associated with a probe in the vicinity of the predetermined portion of the object with reference to a third coordinate frame; and registering the first, second and third data sets to generate a matched image data set in which the first, second and third coordinate frames are relatively aligned with one another.

System and method of registration of three-dimensional data sets

An image processing system and methods of operation within such a system are disclosed. The image processing system utilizes a class model defined by one or more relative relationships between a plurality of image patches. The relative relationships describe the overall organization of images within an image class. The relative relationships are encoded in a global deformable template which can be used to classify or detect images. The class model may be predefined or generated by an image processing system.

Method and apparatus for classifying and identifying images

The present invention provides an image data registration system and method of storing a first data set of three-dimensional image data associated with a predetermined portion of an object with reference to a first coordinate frame; obtaining and storing a second data set of three-dimensional image data associated with a surface of the predetermined portion of the object with reference to a second coordinate frame; and registering the first data set and the second data set to generate a matched image data set in which the first coordinate frame is aligned with the second coordinate frame. In an alternative embodiment, the present invention provides a method of registering three-dimensional data sets, comprising generating a first data set of image data with reference to a first coordinate frame; generating a second data set of image data with reference to a second coordinate frame; selecting a predetermined subset of data points from the first data set; matching the subset of data points to all possible corresponding subsets of data points associated with the second data set and producing a set of hypothesized transformation data sets; and sequentially mapping said second data set to each of the hypothesized transformation data sets to form a solution data set, the solution data set representative of a highly accurate transformation of the second data into the first coordinate frame associated with the first data set.
