Improved Image Deblurring based on Salient-region Segmentation
This addresses blur removal in images for applications like photography or vision systems, but appears incremental as it builds on existing deblurring techniques.
The paper tackled spatially-variant image deblurring by proposing a saliency-based approach for segmentation and a PDE-based method for prediction and optimization, resulting in effective performance as shown in experiments.
Image deblurring techniques play important roles in many image processing applications. As the blur varies spatially across the image plane, it calls for robust and effective methods to deal with the spatially-variant blur problem. In this paper, a Saliency-based Deblurring (SD) approach is proposed based on the saliency detection for salient-region segmentation and a corresponding compensate method for image deblurring. We also propose a PDE-based deblurring method which introduces an anisotropic Partial Differential Equation (PDE) model for latent image prediction and employs an adaptive optimization model in the kernel estimation and deconvolution steps. Experimental results demonstrate the effectiveness of the proposed algorithm.
