Class GrayLinComb
java.lang.Object
jjil.algorithm.GrayLinComb
- All Implemented Interfaces:
- Ladder.Join
public class GrayLinComb
- extends java.lang.Object
- implements Ladder.Join
Computes linear combination of two Gray8Images. Result is
(a*first image + b*second image) / c. The signed image values are shifted so
the minimum value is 0 and the result is then shifted back to the signed
range.
Intended to be used as a combination stage in a ladder operation.
