NUMB3RS - Season 3 - "Pandora's Box" - Thinking Backward
Activity Overview
In "Pandora's Box," Charlie uses a wavelet-based deconvolution algorithm to 'unsmear' a smudged fingerprint. A deconvolution algorithm analyzes a picture, sharpens the edges, and restores details "thus finding the picture beneath the smear." Finding such an algorithm to determine a clear image of a fingerprint is an example of solving an inverse problem.
Students explore two inverse problems after considering a simulation of a deconvolution algorithm on the graph of a function.
