| 摘 要： | 针对水下视频图像对比度低、图像模糊和噪声突出的特点,提出一种新的基于凸集投影(POCS)的超分辨率图像重建与增强算法。在POCS迭代约束的过程中,采用小波域非线性函数抑制噪声并突出细节,然后用能量非递减性约束集进行修正。实验表明,该方法具有较好的超分辨率重建与增强效果。

| Abstract: | According to the low contrast,strong noise and image blur of underwater video images,a new super-resolution reconstruction and enhancement algorithm based on projection onto convex set(POCS) algorithm is proposed.In the process of POCS iterative constraint,the wavelet transform domain nonlinear function is used to de-noise and to enhance the details of the target.Then the non-decreasing energy constraint is used to revise iteration process.The experimental results show that the proposed algorithm has a good... |
