Abstract

A method (1300) and a system (1000) for filtering thermal image data is provided. The method (1300) comprises: capturing (1302) thermal image data by a thermal image detector (1110); forming (1304) a signal distribution of intensity values; identifying (1306) a first part (220) in the signal distribution of intensity values, the first part being a peak having an intensity width (222) equal to or smaller than a predetermined intensity span being based on a resolution parameter of the thermal image detector; identifying (1307) a second part (210) having an intensity width larger than the predetermined intensity span; determining (1308) an intensity range between the first part and the second part; and filtering (1310), if the intensity range is larger than a predetermined minimum intensity range, the thermal image data by excluding thermal image data forming part of the first part.
