We present a spatio-temporal energy minimization formulation for simultaneous video object discovery and co-segmentation across multiple videos containing irrelevant frames. Our approach overcomes a limitation that most existing video co-segmentation methods possess, i.e., they perform poorly when dealing with practical videos in which the target objects are not present in many frames. Our formulation...
To remove the stripe noises from the polluted line-scan color images, a transform domain destriping method which combined Fourier transform and wavelet decomposition was presented. Firstly, the line-scan color image with stripe noise was decomposed using multi-resolution wavelet to separate the sub-band which contained the stripe noise from the other sub-bands. Then the sub-band with stripe noises...
The performance of call graph analytics is critical to the development and management of large-scale software systems. Classical call graph visualizers either reuse a plain node-link graph metaphor that does not scale, or adopt the specific aggregation technique like the PivotGraph. In this paper, we first generalize the OLAP analysis framework from multidimensional data to multivariate graphs. Then...
A equation, Emes = B·Ep, to deduce from the Ep(photopic illumination) to Emes(mesopic equivalent illumination) is proposed, where B is instant for modified coefficient. The equation is used to calculate the mesopic equivalent illumination of the different color temperature LED light sources under mesopic light levels.
