Horizon tracking is an important operation in 3-D seismic data processing,and the tracked horizon can be used by the experts to detect the earth's subsurface structure.Processing speed is a major bottleneck in seismic horizon tracking since the data size of 3-D seismic data is usually very huge.In this paper,present a new automatic horizon tracking algorithm,which is based on CUDA technique.The algorithm fully utilizes the many-core structure and the high performance computing ability of GPU,realizing a large scale parallel method for horizon tracking.The results of experiments show that the algorithm has an obvious speedup than the traditional CPU-based horizon tracking algorithm.
