ABSTRACT
High quality infrared (IR) imagery from staring focal plane arrays has reached or exceeded TV resolution. High quality infrared (IR) imagery from staring focal plane arrays has reached or exceeded TV resolution. The prototype for such methods is the well-known technique of histogram equalization described in many texts on image processing. To accomplish such a locally enhanced display, one must depart from global, monotonie mappings. Low-contrast details such as those on the cups are frequently not discernible in such mappings. Hence, the processing, display, and enhancement of high-resolution wide-dynamic-range staring IR imagery, whether for soft-copy display or in real-time hardware embodiments, is becoming an important topic in image processing, but one still in the early stages of development. A basic difference between the algorithms in subsection and all previous algorithms should be underscored. Here we are not mapping from raw signal to display values but are rather preprocessing the raw signals.
