The researchers used ImageJ software along with a Kodak grey scale and located very good arrangement in between the optical measurement techniques and smoke sample illustrations or photos designed alongside wall surfaces. Their study confirmed that “the smoke pattern was firm for that wall exams and confirmed a distinction between check conditions and Great arrangement for the method for all take a look at problems” (Riahi 2012). They also mentioned that “depending on the thoroughly clean zone space, the flame peak and also the fire sizing is often calculated” (Riahi 2012).
