氮氧化物(NOx)污染是我国亟待解决的重大环境问题。NOx是形成光化学烟雾和雾霾二次颗粒物(PM2.5)的重要污染物和前驱体，其主要源于工业锅炉的高温燃烧。我国工业锅炉中有70%属于中小型锅炉，然而，应用于大型锅炉的成熟脱硝(De-NOx)技术——选择性催化还原烟气(SCR)干法脱硝技术，因其对中小型锅炉不具有成本效益而难以适用。因此，探索新型高效的烟气脱硝方法对于严格执行中小型锅炉达标排放、保障...

Aim to striping noise brought by non-uniform response of remote sensing TDI CCD, a novel de-striping method based on statistical features of image histogram is put forward. By analysing the distributi...
A UNIVERSAL DE-NOISING ALGORITHM FOR GROUND-BASED LIDAR SIGNAL
Ground-based lidar Universal de-noising Signal segmentation Dual field-of-view Mie lidar
2016/7/4
Ground-based lidar, working as an effective remote sensing tool, plays an irreplaceable role in the study of atmosphere, since it has the ability to provide the atmospheric vertical profile. However, ...
De-Emphasis of Distracting Image Regions Using Texture Power Maps
Texture Power Maps Distracting
2016/5/24
We present a post-processing technique that selectively
reduces the salience of distracting regions in an image.
Computational models of attention predict that texture variation
influences bottom-u...
We present a semi-automated technique for selectively deanimating
video to remove the large-scale motions of one or more
objects so that other motions are easier to see. The user draws
strokes to i...
