摘要: The goal of this paper is to correct bleed-through in degraded documents using a variational approach. model adapted an estimated background according the availability verso side document image. Furthermore, for latter case, more advanced based on global control, flow field, introduced. solution each resulting obtained wavelet shrinkage or time-stepping scheme, depending complexity and nonlinearity models. When both sides are available, proposed uses reverse diffusion process enhancement double-sided images. results experiments with real synthesized samples promising. model, which robust respect noise complex background, can also be applied other fields image processing.
