Image based correction for unwanted light signals in a specific region of interest

摘要

A method for correcting the signal in an image having a plurality of regions of interest, the method comprising the steps of:
(a) providing an image having a plurality of regions of interest, these regions of interest having areas between them;
(b) determining a region of correction between at least two regions of interest;
(c) calculating a correction signal from the region of correction; and
(d) using the correction signal to correct a measured signal from one or more regions of interest. This invention also provides a method for defining a region of correction for use in a method for correcting the signal in an image having a plurality of regions of interest, the defining method comprising the steps of:
(a) providing an image having a plurality of regions of interest;
(b) extracting geometric information for a plurality of regions of interest;
(c) selecting a location between at least two regions of interest;
(d) selecting at least one parameter to describe regions of correction; and
(e) constructing regions of correction between the at least two regions of interest.
