“…(c) Features extraction from TC images Mean (M), variance (V), density (D), decentricity (DC), area of cyclone (AC) and area of eye (AE) are extracted from a TC image. First, Centre of Gravity (CoG) needs to be calculated based on work done by Onodera [29] for finding the features such as mean, variance (V), density (D), decentrcity (DC) [10,11,29,30]. The following formulas are used on image I of size m × n to calculate the CoG:…”
