Abstract: “Reconstruction of an underwater object from a sequence of images distorted by moving water waves is a challenging task. A new approach is presented in this paper. We make use of the bispectrum technique to analyze the raw image sequences and recover the phase information of the true object. We test our approach on both simulated and real-world data, separately. Results show that our algorithm is very promising. Such technique has wide applications to areas such as ocean study and submarine observation”
