Abstract Guiding image segmentation with edge information is an often employed strategy in low level computer vision. To improve the trade-off between the sensitivity of homogeneous region delineation and the oversegmentation of the image, we have incorporated a recently proposed edge magnitude/confidence map into a color image segmenter based on the mean shift procedure. The new method can rec...

Because of the conservation of mass, the divergence of the moisture transport integrated over the depth of the atmosphere should balance the fresh water flux (evaporation-precipitation) at the surface. Monitoring these two terms is critical to the characterization of the hydrological cycle and climate change. Direct in situ measurements of moisture transport, evaporation, and precipitation are ...

WS2@C nanoflowers modified polypropylene separator (WS2@C-PP) can effectively adsorb lithium polysulfides and catalyze their conversion on the adsorptive/electrocatalytic sites of WS2. The unique design carbon coating WS2 maximizes synergism polarity conductivity, benefiting recycling active materials, while forming uniform stable layer.
