Paper Abstract

As part of a project to utilize advanced software to diagnose multi-layer circuit card assemblies, the signal traces were separated into top and bottom layers. The source images were stereo x-ray images, 2 K by 2 K by 12 bits. The a stereo software algorithm was developed using steerable filters as a means of precisely determining signal trace location and orientation. A new stereopsis algorithm was derived which efficiently allocates signal traces to particular layers. The paper relates the approach taken to biological vision and its characteristic of hyperacuity. And to the subject of model building and model fitting.
