The gray and space feature of infrared quasi imaging is analyzed. Bicolor ration discernibility is applied to reject false targets. Gray expansion is used in quasi imaging. Iterative sub-block gray histogram bilevel is studied for quasi images, and then fuzzy spatial segmentation is adopted for 2-bit image. Recognition feature of unit scan imaging is presented. Infrared quasi image frames registration is used to improve detection rate. The recognition method minishes the original false and omission possibility. Successive segmentation and recognition with original locking are studied. The experiment reveals that infrared bicolor recognition is proper for stationary, slow, and fast infrared targets and it can be realized in real time.\;
