摘要: A hierarchical quality-guided phase unwrapping algorithm in a shared memory environment is proposed. First, the wrapped divided into regular blocks, and local wrap counts of every block are obtained by strategy. Then, gradient adjacent blocks quality defined boundary block. Each block's data can be regarded as an abstract point, strategy used again to solve each Finally, absolute point adding corresponding counts, then final unwrapped obtained. The performance proposed verified through experiment performed on simulated real interferometric synthetic aperture sonar environment. results show that method greatly improves efficiency while maintaining correctness results.
