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.

Improving vertical resolution for density curves is by means of restructuring the response from large and small spacing sondes and borehole effect correction factor and coherence factor are used. Form the principle of GR logging, calculate volumes in investigating areas taken by borehole, formation, up and low shoulder beds, along with distance between center of gravity of the four unit bodies and detector. Based on the above, the weighting function of each unit body to GR signal contributions are established, thus realizing processing of GR logs with high resolution. The resistivity logging model uses "resolution matching" method to improve the resolution of the logs. After the process, PNN model is made to recognize the oil-gas-water bed. Compared with BPNN, the net work is featured swiftness, accuracy and ease of practical application.
