报告人题目:Discriminative Learning in Image Restoration


摘要:In this talk, we summarize our work on image restoration from three aspects. First, given a test noisy image, we described an approach to estimate hyper-parameters of gradient-based image model, and suggested a gradient histogram preservation method for image denoising. Second, give a set of image pairs of blurring/clean images, we present a discriminative learning method to learn iteration-wise priors for blind deconvolution. Iteration-wise loss, constraint on solution paths, and multi-scale scheme are also incorporated to guarantee its success. By introducing the concept of dynamic guidance, we provide a model for learning weighted analysis representation for guided depth image super-resolution. Finally, we investigate the possiblity to design CNN guided by image modeling, and learn a plain CNN model for image denoising.
