Abstract:
A method of manipulating image data for improved image visualization and analysis, comprising the steps of:providing a library of image processing options; providing digital data representing grey scale values of a two-dimensional image of relevant subject matter and a substantially homogeneous background that at least partially borders on said relevant subject matter, wherein said grey scale values range from 0 to Z where 0 equals black and Z equals white; defining a first sub-image from said two-dimensional image by i) providing a threshold grey scale level between 0 and Z, and ii) comparing said threshold grey scale level to said digital data starting at outer edges of said two-dimensional image and moving inward therefrom to define an outer edge boundary of said first sub-image at which said digital data first becomes greater than said threshold grey scale level, said first sub-image including said relevant subject matter and a reduced amount of said substantially homogeneous background; defining a second sub-image from said first sub-image, said second sub-image substantially defining just said relevant subject matter; selecting a plurality of said image processing options; processing said second sub-image in accordance with said plurality of said image processing options to generate image output data; and displaying said image output data.
