The scientists used ImageJ computer software plus a Kodak grey scale and located superior settlement in between the optical measurement strategies and smoke pattern photographs formulated together wall surfaces. Their analyze confirmed that “the smoke sample was firm with the wall assessments and showed a difference between test conditions and Great arrangement for the method for all exam situations” (Riahi 2012). They also said that “depending on the clear zone place, the flame peak along with the fire dimensions might be calculated” (Riahi 2012).
