Implementation Issues for Level 0 Image Processor Software Within an Application Package

摘要

Image processing is rapidly emerging as a field with many interesting areas for the computer scientist. Packages are available that allow images to be manipulated in an interactive environment by applying functions to the image. Functions are defined as transformations from the image memory domain to the display domain, which may permanently alter image memory values. This paper describes minimum hardware constraints and the scope of modifications necessary to implement different image processors within the Earth Resources Laboratory Applications Software (ELAS) environment. It also contrasts the impact on software engineering principles related to the implementation of low-level software to support the imaging functions. Keywords: Fortran; VAX II/980 computers. (KR)
