This work proposes a new method for place recognition based on the scene architecture. From depth video, we compute 3D model and derive describe geometrically 2D map from which descriptor is deduced to constitute core of proposed algorithm. The obtained results show efficiency robustness propounded appearance changes light variations.

objective: when none of digital systems and scanners is accessible and it is essential to have digitized images of conventional radiographs, digital cameras can be used. the aim of this study was to investigate whether digital images obtained by different resolutions of a digital camera are matched to the original radiographs in evaluation of caries. methods: in this diagnostic accuracy in vitr...

Interpolators are widely used in image processing because they allow us to estimate the unknown values of sensor measurements. In this research, we present a comparison between commonly used interpolators to evaluate how each affect the behavior of the data, it is studied the problem of interpolation as a means to infer information at a higher frequency through the mathematical description an d...
