Abstract

Image enhancement techniques based on a composition of uncorrected subband coefficients called "wavelet" features are demonstrated on printed circuit board images for fault detection objectives as applied to an automated inspection system. The wavelets are used to preprocess the imagery for enhancing and filling the holes on the images of the conducting connections. Several image enhancement techniques are demonstrated and described to make visual performance comparisons.
