Virtual biological object`s e.g. colon, characteristics paths e.g. prone position, regulating method for e.g. angioscopy, involves measuring correlation between object paths by minimizing energy function that includes error and switch terms

摘要

The method involves receiving two paths, and parameterizing the two characteristics paths of a virtual three dimensional biological object. Correlation between the two paths is measured by minimizing an energy function, where the energy function incorporates an error term and a switch term. The error term is a function of position difference and/or two deviations of concurrent and/or corresponding discrete sub intervals in the paths. The switch term is a function of length of concurrent and/or corresponding discrete sub intervals in the paths. Independent claims are also included for the following: (1) a computer readable medium with a set of instructions that are executed by a computer to regulate two characteristics paths (2) a device for regulating two characteristics path of a three dimensional biological object.
