A 3D Simplification Method based on Dual Point Sampling

Juan Cao, Yitian Zhao, Ran Song, Yingchun Zhang
2013 Journal of Multimedia  
A watermarking algorithm against print-and-scan attack based on PSO (Particle Swarm Optimization) is proposed in this paper.  ...  The experimental results show the halftone watermarking algorithm optimized using PSO has better performance, it is robust under smearing attack and cropping attack, and has good resistance to print-and-scan  ...  We also thank the anonymous reviewers for their suggestions and feedback that helped us to improve the quality of this paper.  ...

Unmasking Clever Hans predictors and assessing what machines really learn

Sebastian Lapuschkin, Stephan Wäldchen, Alexander Binder, Grégoire Montavon, Wojciech Samek, Klaus-Robert Müller
2019 Nature Communications  
Current learning machines have successfully solved hard application problems, reaching high accuracy and displaying seemingly intelligent behavior.  ...  This showcases a spectrum of problem-solving behaviors ranging from naive and short-sighted, to well-informed and strategic.  ...  For images showing horses, the model has learned to dominantly decide based on the presence of a copyright watermark on one of the corners of the images.  ...

Ignacio Martin, Sebastian Troia, Jose Alberto Hernandez, Alberto Rodriguez, Francesco Musumeci, Guido Maier, Rodolfo Alvizu, Oscar Gonzalez de Dios
2019 IEEE Transactions on Network and Service Management  
The distances based on different norms can also be used, and they receive the generic name of r norms. In this case r = 2 is the above-defined 2 norm.  ...  Euclidean Distance Is the most straightforward and common definition of distance inside an n-dimensional Euclidean space where points have n dimensions and for which distance is the 2 norm: d( x, y) =  ...

Efficient image duplicate detection based on image analysis

Yannick Maret
2007
The proposed method is referred to as content-based since it relies only on content analysis techniques rather than using image tagging as done in watermarking.  ...  La technique proposée est basée sur le contenu car elle utilise des techniques d'analyse d'image plutôt que le marquage comme cela se fait dans le watermarking.  ...  A typical distance is based on the L 1 -norm.  ...
