Deblurring the Enlarged Digital Image by Using the Iteration Method
Wei Liu · Journal of Optoelectronics·laser · 2002
We study the problem of blurring of digital images after interpolation and enlargement by using the iteration method.The blurring can be seen as the result of the convolution of the point spread function and the clear image.We can get the point spread function by the interpolation method.The convolution of digital images is the typical problem of solution linear equation.We get the perfect result by using the Jacobi iteration method.Compared with the method of transformation of spectrum space,there werent problems of denominator equaling zero and the rounding error in the transformation by using the iteration method.
