AB - <p style="text-align: justify;">Total variation regularization has good performance in noise removal and edge
preservation but lacks in texture restoration. Here we present a texture-preserving
strategy to restore images contaminated by blur and noise. According to a texture
detection strategy, &nbsp;we apply spatially adaptive fractional order diffusion. A fast
algorithm based on the half-quadratic technique is used to minimize the resulting
objective function. Numerical results show the effectiveness of our strategy.</p>
