SimpleITK

Simple ITK

Goals

• Provide an easy-access layer to ITK for non-C++ expert developers

Sandbox

• http://github.com/dblezek/SimpleITK

Scope

Suggested Areas to Cover

• IO
• Basic Filters
• Registration
  • Basic Framework
  • Deformable registration
    • BSplines
    • Demons
• Segmentation
  • Region Growing
  • Level Sets
  • Classifiers

Types

• Image pixel types supported
  • int8_t
  • int16_t
  • int32_t
  • float
• Image dimensions supported
  • 3D
  • Is 2D managed as a 3D image of 1 slice ?
    • Performance penalty for neighborhood filters... ?
    • Could be "2D" versions of 3D filters, i.e. RecursiveGaussianFilter2D. This would work on a slice-by-slice basis.

Languages

Wrapped languages will be any that SWIG supports, if someone is willing to write tests / any needed glue code.

• C++ Layer
• Python
• Lua
• Java
• ?

Implementation Details

• Coding Style
  • Copyright Headers & License
• Const correctness (can we avoid using const's completely?)
• Testing
  • C++ testing (Google Test?)
  • Python tests (PyUnit?)
  • Lua tests (?!?)
  • Java tests (JUnit)
  • ? other languages ?
• Managing basic types
  • Arrays
  • Regions
  • Transforms
• Not so basic types (could these be enums passed as ivars?)
  • Interpolators
  • Optimizers
  • Metrics

Plan

• Image classes
• IO

• General architecture
• Wrapping efficiency
• Should SimpleITK be mixable with normal ITK ?
  • At C++ level ?
  • At WrapITK (Python, Tcl ) level ?
• SimpleImage class
  • Include casting to other image types.
