Document images undergo various degradation processes. Numerous models of these degradation processes have been proposed in the literature. In this paper we propose a model-based restoration algorithm. The restoration algorithm rst estimates the parameters of a degradation model and then uses the estimated parameters to construct a lookup table for restoring the degraded image. The estimated de...
متن کاملTasty and healthy TR(i)Ps
For the majority of the developed world, the hunter–gatherer lifestyle that served our predecessors for millennia is a distant memory. yet, despite our increasingly sophisticated approach to food as top chefs compete for Michelin stars, our basic ability to taste chemical signatures and perceive flavour has not changed. in fact, in addition to sight, the ability to taste might have been one of ...
متن کاملA painful TR(i)P to lysosomes
The ion channel TRPA1 detects noxious stimuli at the plasma membrane of neurons and elicits pain and inflammation. In this issue, Shang et al. (2016. J. Cell Biol. http://dx.doi.org/10.1083/jcb.201603081) report that TRPA1 also localizes to lysosomal membranes of neurons, releasing intracellular Ca2+ to trigger vesicle exocytosis and neuropeptide release.

One big obstacle to understanding the nature of hierarchical task network (htn) planning has been the lack of a clear theoretical framework. In particular, no one has yet presented a clear and concise htn algorithm that is sound and complete. In this paper, we present a formal syntax and semantics for htn planning. Based on this syntax and semantics, we are able to deene an algorithm for htn pl...
متن کاملCAR - TR - 687 Sept . 1993 CS - TR - 3142 Specification of Interface Interaction Objects
User Interface Management Systems have significantly reduced the effort required to build a user interface. However, current systems assume a set of standard "widgets" and make no provisions for defining new ones. This forces user interface designers to either do without or laboriously build new widgets with code. The Interface Object Graph is presented as a method for specifying and communicat...
