Microalgae image denoising algorithm based on stack

The algorithm based on stack to remove the small area noises in binary microalgae image is presented in this paper. The denoising of image is accomplished by using this algorithm through scanning image one time. The new algorithm not only preserves signal´s original features, but also has stronger ability to remove noise. The numerical experiments have shown that the algorithm is very effective in noise reduction, and is better than traditional method in complexity and running time of the image denoising.
