Basic Concepts

  • Data Types
    • Binary
    • 8 Bit, 3 x 8 Bit, 16 Bit, 32 Bit integer
    • 64 Bit floating point
    • 64 Bit floating point complex
  • Parent-Child Relation
    • Most object types in Vision can have child- objects. A rectangular area in a larger image may be displayed using a child- image. Individual bands or sub-sequences may also be implemented using child-images. A child object does not have it’s own data; it offers a new view of the data of the parent object. It may have it’s own text and graphical annotations however.
  • Overscan
    • All neighborhood functions use the selected overscan mode: transparent, replace or extend
  • Network
      • Vision supports loading and saving of files across a network
  • Multitasking and Multithreading
    • Vision can execute several functions at the same time
    • A progress indicator shows the status of running processes
    • A process may be stopped or paused at any time
    • A paused process may be resumed
    • The Vision user interface remains fully responsive and may be used to initiate new actions while other processes are executing.
