Figure 6.

An example of different thermal data calculation methods on the same sample: (top) averaging of all the pixel temperature data: before (left) and after (right) the Gaussian window; and (bottom) integrated values of all the pixel temperature data: before (left) and after (right) the Gaussian window. The integrated values suddenly increased as they approached around the 200th frame (red box (bottom)). In this case, the camera approached the cattle during the time of the 200th frame. The X-axis indicates the frame number (10 fps, frames per second) and the Y-axis indicates temperature (top) or the integrated value (bottom).
