Image Analysis using Soft Histograms
2001 (English)In: Proceedings of the SSAB Symposium on Image Analysis: Norrköping, 2001, 109-112 p.Conference paper (Refereed)
This paper advocates the use of overlapping bins in histogram creation. It is shown how conventional histogram creation has an inherent quantisation that cause errors much like those in sampling with insufficient band limitation. The use of overlapping bins is shown to be the deterministic equivalent to dithering. Two applications of soft histograms are shown: Improved peak localisation in an estimated probability density function (PDF) without requiring more samples, and accurate estimation of image rotation.
