8. Future Work
The following improvements are being considered and are being worked on. Optimise the feature vectors and minimize the number of output points required to identify the yet to propagate internal flaw.
Studying different implementations of DFT such as nearly optimal sparse Fourier Transform to understand the effect they have on speed and efficiency.
We are also working on methods to measure the dimension of the object from its acoustic response.
Detection of other minor defects such as under fillings and lap in forgings are also being worked on.
