BIT-PLANE STACK FILTER ALGORITHM FOR FOCAL PLANE PROCESSORS

This work presents a novel parallel technique to implement stack morphological filters for image processing. The method relies on ap-plying the image bitwise decomposition to manipulate the grayscale image at a bit-plane level, while simple logical operations and Pos-itive Boolean Functions (PBF’s) are executed in parallel to derive the transformed bit-planes. The relationship between the bitwise and threshold decomposition is closely investigated and analysed, which lead us to derive an algorithm whose control flow is full bi-nary encoded. Furthermore, the algorithm exhibits an interesting performance, which depends on the image histogram thanks to its hierarchical processing and the study of the relationship among bi-nary decompositions
