Each thermogram (Fig. 1) contained digital information on the temperature values for each of the 76,800 pixels (320 x 240). Sequence of pictures was extracted from the video and based on the grayscale and temperature scale the mean temperature was calculated on the medial aspect of the quadriceps muscle (Fig. 1).
