Abstract
Infrared images typically contain obvious dark-corner noise. It is a challenging task to eliminate such noise with the acceptable computation overhead and time overhead. In this paper, we introduce an effective dark-corner noise removal algorithm consists of two consecutive processing procedures. Firstly, in order to effectively filter dark-corner noise with as few as frames of infrared images, the proposed algorithm accumulates the low-frequency pixels during the several different frames of infrared images and eliminates the dark-corner noise by subtracting this parameter from the original infrared image. Then, this algorithm sets several detection windows for dark-corner noise to obtain another additive correction parameter and subtract this parameter from the original infrared image. We demonstrate the effectiveness of our algorithm from experimental perspective.
