基于盲均衡的超分辨率图像重建

Reconstruction of Super-Resolution Image Based on Blind Equalization

超分辨率图像的重建是指从一组低分辨率图像重建出更高分辨率的图像。提出采用盲均衡与凸集投影的方法估计成像系统的冲激响应 ,并实现超分辨率图像的重建。这种图像重建算法不需要了解关于帧间运动模式与帧内模糊类型的先验知识 ,因而更接近实际应用的要求。

Reconstruction of super-resolution image refers to obtain a higher resolution image from a sequence of low-resolution frames. The technique of blind equalization and projection onto convex sets (POCS) is used in this paper to estimate the impulse response of imaging system and reconstruct the SR image. The algorithm that proposed in the paper does not depend on a priori information about blur type and the model of inter-frame motion, therefore it is more efficient in application. The experiment proves the effectiveness of the proposed algorithm.
