Study and Application of Digital Image Reconstruction
Yan Wenzhong, Baiying Lei · The Open Cybernetics & Systemics Journal · 2015
Digital image reconstruction is a sound method to reveal the underlying images hidden in fuzzy and noisy data.The main defiance of this method is its sensitivity to measure noise in the input data, which will result in large artifacts in the reconstructed image.So it has become very important that finding a robust method to remove the noise and reconstruct the image.For the purpose of acquiring a gray image without loosing information from it, a method of removing noise from a gray image and reconstructing this image was proposed in this paper.The proposed method mainly used the opening-by-reconstruction. In order to test the efficacy of this method, it is used to isolate the text out of the image of calculator keys.The experimental results showed that the method is efficient.
