An adaptive halftoning method where the difference between a digital image and a filtered digital image is introduced into the system on a pixel by pixel basis is disclosed. In this method, each input difference pixel has a corresponding error value of the previous pixel added to the input value at a summing node, resulting in modified image difference data; the modified image difference data is passed to a threshold comparator where the modified image difference data is compared to a threshold value, the threshold value varying according to the properties of the digital image, to determine the appropriate output level; the output level is subtracted from the modified image difference value to produce the input to an error filter; the output of the error filter is multiplied by an adaptation coefficient, where the adaptation coefficient varies according to the properties of the digital image, to generate the error level for the subsequent input pixel; and, the cyclical processing of pixels is continued until the end of the input data is reached.

In the method disclosed, three or more infrared images of a body having concealed objects are acquired, each image resulting in a response of a detector having a spectral sensitivity in the infrared that is analogous to one of the spectral sensitivities of the color response of the human eye, and each image corresponding to a different spectral sensitivity. At least the center of the spectral sensitivity corresponding to the Green response at the human eye is selected to allow increasing the detected radiation difference between the concealed object and the body. The responses of the detector to each of the three or more images are utilized to provide RGB signals to a display device. The color image displayed in the display device allows identifying the concealed object.
