Parallelized Dilate Algorithm for Remote Sensing Image

الملخص EN

As an important algorithm, dilate algorithm can give us more connective view of a remote sensing image which has broken lines or objects.

However, with the technological progress of satellite sensor, the resolution of remote sensing image has been increasing and its data quantities become very large.

This would lead to the decrease of algorithm running speed or cannot obtain a result in limited memory or time.

To solve this problem, our research proposed a parallelized dilate algorithm for remote sensing Image based on MPI and MP.

Experiments show that our method runs faster than traditional single-process algorithm.
