Abstract
A system and method are provided for prior-constrained mean shift analysis of a data array, the system including a processor, an input adapter in signal communication with the processor for receiving at least one data array, and a prior constraints unit in signal communication with the processor for performing a prior-constrained mean shift analysis on the at least one data array; and the method including receiving initialization data, selecting an initial point relative to the initialization data, Gaussian fitting with a prior-constrained mean shift responsive to the initial point to parse a structure, and setting the parsed structure as a prior constraint.
Claims20
A method (200) for prior-constrained mean shift analysis of a data array, comprising:
- receiving (212) initialization data;
- selecting (216) an initial point relative to the initialization data;
- Gaussian fitting (218) with a prior-constrained mean shift responsive to the initial point to parse a structure;
- and
- setting (220) the parsed structure as a prior constraint.
A system (100) for prior-constrained mean shift analysis comprising:
- a processor (102);
- an input adapter (112, 114, 128, 130) in signal communication with the processor for receiving at least one data array;
- and
- a prior constraints unit (170) in signal communication with the processor for performing a prior-constrained mean shift analysis on the at least one data array.
A program storage device readable by machine, tangibly embodying a program of instructions executable by the machine to perform program steps for prior-constrained mean shift analysis, the program steps comprising:
- receiving initialization data;
- selecting an initial point relative to the initialization data;
- Gaussian fitting with a prior-constrained mean shift responsive to the initial point to parse a structure;
- and
- setting the parsed structure as a prior constraint.
