Fuzzy Measurement of the Number of Persons on the Basis of the Photographic Image
The numbers of persons on the hall is often a base of the ventilation control system in big commercial buildings. The paper presents a method dedicated for the measurement of the number of persons on the basis of analysis the registered photographic images. A difference between consecutive frames is estimated in the presented method. Every 5 seconds a change in a frame is being evaluated towards previous one. Medium value of the changes for the period of a few minutes is proportional to the number of persons on the hall. For the implementation the algorithms based on fuzzy logic were used.
