Basic image processing operations such as thresholding are often difficult to use in industrial settings because of nonuniformities in scene illumination. However, these illumination variations can be reduced or eliminated entirely if appropriate image processing techniques are applied prior to level-sensitive processing. Useful procedures for reducing the effects of illumination variations are covered in this paper including background subtraction, high-pass filtering and the use of homomorphic filters. Hardware considerations for performing these operations in real-time systems are also discussed.
