Abstract
Method and system for improved contrast enhancement. The method includes receiving, from at least one imaging system, first and second component chiral images, the first component chiral image being captured by a first filter that is polarized in a first direction, the second component chiral image being captured by a second filter that is polarized in a second direction, the second direction being substantially orthogonal to the first direction. The method also includes pre-enhancing, by a processor, one or both of said first component chiral image and said second component chiral image. Then the processor weights and sums at least a portion of the first and second component chiral images. Weighting and summing may be repeated until an optimal weight is reached. A contrast enhanced image may be generated after the optimal weight is reached.
