Deblurring in AFM images
Atomic Force Microscopy (AFM) has been widely used in the material and life sciences and has enabled much progress in nanotechnology since it was invented. AFM relies on inter-atomic forces to form a topographical map of a sample surface. Depending on the surface type, it is possible to achieve atomic resolution. However, due to either the microscope design and operation mode or external enviro...
متن کاملDeblurring Face Images with Exemplars
The human face is one of the most interesting subjects involved in numerous applications. Significant progress has been made towards the image deblurring problem, however, existing generic deblurring methods are not able to achieve satisfying results on blurry face images. The success of the state-of-the-art image deblurring methods stems mainly from implicit or explicit restoration of salient ...
متن کاملAdaptive deblurring of noisy images.
We propose a practical sensor deblurring filtering method for images that are contaminated with noise. A sensor blurring function is usually modeled via a Gaussian-like function having a bell shape. The straightforward inverse function results in the magnification of noise at high frequencies. To address this issue, we apply a special spectral window to the inverse blurring function. This speci...
متن کاملMultichannel deblurring of digital images
Blur is a common problem that limits the effective resolution of many imaging systems. In this article, we give a general overview of methods that can be used to reduce the blur. This includes the classical multi-channel deconvolution problems as well as challenging extensions to spatially varying blur. The proposed methods are formulated as energy minimization problems with specific regulariza...
متن کاملDeblurring traffic sign images based on exemplars
Motion blur appearing in traffic sign images may lead to poor recognition results, and therefore it is of great significance to study how to deblur the images. In this paper, a novel method for deblurring traffic sign is proposed based on exemplars and several related approaches are also made. First, an exemplar dataset construction method is proposed based on multiple-size partition strategy t...
