Hybrid Measurements of Image Histograms, with an Application to Texture Discrimination
Ch. Thum · Optica Acta International Journal of Optics · 1983
Histograms of images show frequencies of occurrence of different grey levels in an image. Uses of such histograms include image encoding, defocus measurements and texture discrimination. Our three aims are to simplify the determination of histograms by measuring only a few moments of the histogram, to achieve fast hybrid electro-optical measurement of the moments and other statistical features, and to apply these measurements to texture discrimination.
