The paper presents the automatic method to examine the histological Whole Slide Images of hemorrhoids. The specimen were stained by Hematoxiline and Eosine, and evaluated by number of vessels, occurrence blood clots and hemorrhage. The proposed method is based on colour deconvolution, mathematical morphology, decision tree classification, region growing operation and region reconstruction. The results of algorithm were compared with medical expert results, what confirmed efficiency of presented algorithm. In 80% of cases, vessels were correctly detected. In 85% cases correctly evaluated occurrence of blood clots and hemorrhages were correctly evaluated in 75% of cases.
