In criminal cases, the information collection and analysis of the scene plays an important role in solving cases. Handprint mark can be easily remaining and frequently occurring mark of criminals. It may occasionally be recognized as potential physical evidence during criminal investigations. The infrared thermal imager can fully collect the thermal radiation information of objects, so it is convenient to get the remaining heat source marks in the environment, and to obtain key information that

Like cell apoptosis is regulated by a rigorous mechanism of a series of genes, handprints also regulated by the mechanism of mark disappearance affected by surrounding pixels. In fact, we can easily get handprint images which hands left a period of time, but hope to restore the initial handprint image and obtain the characteristics of the criminal hand. Therefore, a method of infrared handprint image restoration based on apoptotic mechanism is proposed. Training depends on the existing infrared handprint images, and we can find a relational model between the former and the latter images. Finally, the rough shape of the original infrared handprint can be deduced.
