The underwater images are often distorted due to many factors like Frequency Domain, Motion Blur and Refraction Caused by Waves etc... To reconstruct the distorted images there are two methods namely Multi-frame Blind De-convolution (MFBD) & Bi-spectrum Speckle Imaging (SI). A new technique is proposed called Hybrid Bi-spectrum Multi frame Blind De-convolution (B-MFBD) by taking the advantages of both the methods. The proposed method involves both SI and MFBD techniques. In proposed method, to start the iterative image reconstruction, the MFBD makes use of the output of a bi-spectrum SI estimator. The two existing techniques suffer from slow convergence, by using new method i.e., Hybrid Bi-spectrum MFBD technique that can be overcome. Proposed technique gives a high speed and better performance compared to bi-spectrum SI and multi frame blind de-convolution (MFBD) methods of image reconstruction.
