Abstract

The user-friendly MATLAB-based TIPOD package provides fast, flexible analysis and image reconstruction of large volumes of chemical species tomography data. Initially focused on in-cylinder automotive applications, its scope has been extended and its design modified to permit easier modification and customization. The new version, TIPOD-2013, provides options for: data pre-processing (e.g. filtering, denoising); data referencing; quality-based data selection; image reconstruction (e.g. Landweber with median or wavelet filters, Tikhonov); off-line still-frame display; export to industry- standard video; and flexible simulation for development or validation of optimal sensor arrays. The key features of TIPOD- 2013 are described, along with examples of its use.
