In this paper a new algorithm to digitally restore vintage photographic prints affected by the ”foxing” defect is proposed. The algorithm is composed of several automatic and consecutive steps where detection of damaged areas is coupled with removal methods. The restoration algorithms are based on an inpainting technique and on an additive/multiplicative model. The first one replaces the lost d...

In this paper, we present a novel fast algorithm for surface retouching of geometric objects. A spacemapping technique is used to transform a missing (or damaged) part of a surface into a different shape in a continuous manner. Experimental results are included to demonstrate the feasibility of our approach. The proposed approach shows the obvious relationship between the surface retouching pro...

This paper deals with a numerical technique for the identi®cation of damage on laminated structures. The numerical model is based on a ®rst-order shear deformation ®nite element. When the structure undergoes some kind of damage, its sti€ness is reduced, changing the dynamic response. By considering the sensitivities of the orthogonality conditions of the mode shapes, an algorithm is formulated,...

High resolution nanopatterning of graphene enables manipulation of electronic, optical and sensing properties of graphene. In this work we present a straightforward technique that does not require any lithographic mask to etch nanopatterns into graphene. The technique relies on the damaged graphene to be etched selectively in an oxygen rich environment with respect to non-damaged graphene. Sub-...

Neuroblasts produced by the neural stem cells of the adult subventricular zone (SVZ) migrate into damaged brain areas after stroke or other brain injuries, and previous data have suggested that they generate regionally appropriate new neurons. To classify the types of neurons produced subsequent to ischemic injury, we combined BrdU or virus labeling with multiple neuronal markers to characteriz...

Image inpainting technique is that repairs damaged area or remove areas in an image. In order to deal with this kind of problems, not only a robust image inpainting algorithm should be used, technique of structure generation is also needs to adopt in inpainting procedure. In this paper, we extend an exemplar-based image inpainting method by incorporating Bézier curves to construct missing edge ...

To understand the effects of a cortical lesion it is necessary to consider not only the loss of local neural function, but also the lesion-induced changes in the larger network of endogenous oscillatory interactions in the brain. To investigate how network embedding influences a region's functional role, and the consequences of its being damaged, we implement two models of oscillatory cortical ...

BACKGROUND.Neuroimaging research has showed the reorganisation of the cortical tonotopic map in tinnitus patients. The representation of the tinnitus frequency has shifted to the adjacent areas due to the lack of afferences from the damaged cochlea. Severity has been correlated with the magnitude of the shift. Auditory discrimination training proposed by H. Flor in 2004, designs a procedure to ...
