GRADE-SPATIAL PROCEDURE IN GRADE DECOMPOSITION OF MEDICAL IMAGES
Maria Grzegorek · Journal of Medical Informatics & Technologies · 2011
The paper describes decomposition of gray medical i mages. Pixels of the image are assigned with the va riable values derived from a neighbourhood of the pixel. T hen Grade Correspondence Cluster Analysis is used to order set of pixels according to their grade differentiation and to divide pixels into subsets. Subsets are visuali zed in separate subimages and regions are extracted on principle of spatial neighbourhood in subimage. Influence of a number of subimages is discussed. Then a new grade-spatial pr ocedure is proposed which combines features of grad e similarity and spatial neighbourhoods.
