摘要：
A numerical approximation of the nonlinear diffusion problem appearing in image processing is discussed. The mathematical model is proposed by Catte, Lions, Morel and Coil and represents an improvement of the original model of Perona and Malik. The scheme is linear, based on Rothe's approximation in time and on the finite element approach in space. The approximating solutions converge strongly in C(I, L(2))boolean AND L(2)(I, V) space to the variational solution.
