There is the method of localization of the number on the scoop for transportation of cast-iron on its photo is describes on this article. The method is based on the low-level description of image. There are description of the method stage-by-stage threshold transformation of image to binary with the automatic choice of threshold, cropping of image using histograms of distribution of the brightness, localization of informing areas and selection of informing areas. There are results of the computer experiments too.
