Integration of Neural Network Algorithms

Objective:

• Integrate artificial neural network segmentation into the NA-MIC kit for segmentation of upper extremity regions of interest.

Progress:

• Base algorithm has been developed using the annie neural network library
• Segmentation algorithm has been applied to segmentation of the phalanx bones on the index finger
  • Paper has been published on this initial work

To Do:

• Initial evaluation of this technique has been performed for phalanx bones.
• Need to rework ITK neural network libraries to allow the size of the network to be dynamic configured at run time instead of compile time
  • There are several issues that neeed to be resolved regarding the Neural network I/O in ITK
  • Consider the inclusion of the old ANN code that existed in the BRAINS software
