A parallel processing system was developed to realize real-time restoration and super-resolution processing of huge amount of large size images after investigating its technical scheme
working principle
key algorithms
hardware architecture
parallel technology and et al. First
the system’s working principle and key algorithms of deblur
denoise
super-resolution were presented based on the technical scheme. After analyzing and comparing the two architectures of DSP and Cluster
employ principle of the Cluster’s equipments was given. It is concluded that Cluster is more suited for large scale parallel processing. Then a parallel algorithm model based on the PPF architecture and multi-layer parallel optimization technology based on the hybrid architecture of MPI+OpenMP were introduced. Finally
experiments and analyses were made on processing effect and speed of DSP and computer
following by scale and performance prediction of system. How to choice the number of processes was also discussed. Experimental results show that the parallel system can reduce run time from 2700s to 29.39s
making images improved apparently in sharpness
contrast and resolution. It can satisfy our application and have a universal property。
