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...

AbstractImage inpainting or image retouching is the method of filling in or repairing the missing area of an image from the nearby pixels information by some algorithm. Its goal is to recover images with limited data loss and tries to obtain outputs of damaged area of an image in such a way that the recovered images look identical to original image. In our proposed method we will divide the dam...

Feather pecking is a problem in commercial laying hens, particularly in loose-housing systems, where many hens can be affected by only a few feather peckers. In addition, feather pecking can become an even larger problem if it spreads throughout the flock. There are several possible ways that feather pecking may spread. The simplest way is that one hen may damage the feathers of a hen, and anot...

BACKGROUND We have developed techniques to implant angiogenic patches onto the epicardium over regions of infarcted cardiac tissue to stimulate revascularization of the damaged tissue. These experiments used a scaffold-based 3D human dermal fibroblast culture (3DFC) as an epicardial patch. The 3DFC contains viable cells that secrete angiogenic growth factors and has previously been shown to sti...

The Tohoku earthquake of March 11, 2011, caused gigantic tsunamis and widespread devastation. Various high-resolution satellites quickly captured the details of affected areas, and were used for emergency response. In this study, high-resolution preand post-event TerraSAR-X intensity images were used to identify damaged buildings. Since the damaged buildings show changes in backscatter intensit...

abstractaccidents and natural disasters and crises coming out of them indicate the importance of an integrated planning to reduce their effected. therefore, disaster relief logistics is one of the main activities in disaster management. in this paper, we study the response phase of the disaster management cycle and a bi-objective model has been developed for relief chain logistic in uncertainty...

in this research an algorithm based on monte carlo simulation is introduced to assess the risk of fire following earthquake in residential, industrial, educational, and governmental land-uses in district no. 20 of tehran. the proposed algorithm consist of different modules including hazard analysis, vulnerability assessment, leak and break analysis of damaged pipeline, ignition probability anal...
