To detect Human-Aura from a Digital Image

Project is based on detection and pattern generation of Human Aura (Human Bio-Field) from a digital image (image must be captured by normal digital camera but not by professional cameras). No other hardware, other than digital camera and laptop for processing, should not be used. There are various techniques available using hardware like Krilian photography, Gas Discharge visualization and so on. But these are methods are costly because of use of hardware. Hence I want it should be done by without making use of costly hardware. The concept behind this is interference of light, as white light (with full spectrum), flash light and energy released from human body (aura) get interfere with each other and form a pattern, which is still invisible but captured by a camera. Thus need an image processing techniques to convert these invisible patterns into visible ones.
