The study of image inpainting for infrared imaging system Based on micro-cantilever FPA

MEMS thermal transducer is a promising technological platform for uncooled IR imaging. We fabricated MEMS IR FPA based on bi-material micro-cantilever and structured an uncooled MEMS IR System. In addition we obtained IR images of room temperature objects by it. Considering simplicity, low cost and efficiency the FPA readout is performed using an optical readout scheme in this system. The problem is some 'holes' will appear in the infrared images when some pixels of the FPA can not be detected by the readout. This paper present an algorithm based on the space pixel point. The algorithm can judge the characteristics of these 'holes' by using the follow parameters Average gray, Discrete and Regional gradient. After finding the 'holes' we can inpaint these 'holds' by the method of Regional growth. We have applied it to image output successfully. We present this algorithm and our results in the paper.
