In this paper, thermogram was used to do human face recognition. The thermogram of human face was captured from infrared camera. Image processing technologies were used to preprocess the captured thermogram. Then several features were extracted from the processed thermogram. These features included the distribution of temperature statistics, the perimeter of the face, the length/width ratio of the smallest rectangle which contained the face, and the triangle formed from the three lowest temperature points of the two cheeks and the chin. A three-layer back-propagation neural network was used as the recognition tool.

In the temperature range between 15 oC and 25 oC, the plateau height increases with increasing temperature. However, in the temperature range between 33 oC and 45 oC, the plateau height decreases with increasing temperature. The results reveal that additional chemical reactions other than the enantiomerization of thioridazine are involved.
在15 oC~25 oC间,平台的高度随温度增加而上升,但在27 oC~33 oC间平台的高度已不再增加,甚至在33 oC以后,平台的高度反而随著温度的上升而下降,此现象显示分析物的对掌异构转换过程中,会随著温度的升高而涉及其他化学反应的参与。
