In industrial applications, thermal infrared radiance mainly corresponds to the surface temperature of the target being studied. Since the contrast of an infrared image is usually much lower than that of a visible image, pseudocoloring techniques are usually used in real- time thermal image display. Pseudocoloring schemes for infrared video should be evaluated according to its ease with which the temperature variance can be distinguished intuitively. In this paper, two uniform brightness schemes for thermal infrared image pseudocoloring are presented. One of the new schemes is derived from the well-known Bezier/Bernstein blending function, and the other one is based on the popular HSI color model. They are compared with a conventional pseudocoloring scheme and a modified conventional scheme. Some representative experimental results are illustrated to show the unique features of the new pseudocoloring schemes.
