以阜新煤矿区矸石山和排土场为研究对象,采用变异系数和有效水分参数相结合的方法,研究土壤水分时空分布对植被恢复的影响。结果表明:受土壤物质组成及形成方式的影响,矿区3个典型样地土壤水分的变异系数和有效水分参数均存在较大差异,并直接影响地上植被的生长。现有植被根系的分布对各层土壤水分尚未达到最佳利用效果。在生态重建时,排土场覆土平台应以草本和浅根灌木相结合为主,慎栽深根植物;排土场自然风化平台应以野草
Automatic image completion can provide convenient editing of consumer images.Most image completion methods find the best patch locally and then copy it to the hole region for texture inpainting.Since
Image salient region detection is very useful in many multimedia applications,such as image retrieval,adaptive content delivery,and adaptive compression.Most existing methods are based on centersurrou
We propose an intermediate computational step,frequency domain filtering of gradient image,to improve contour detection performance of gradient-based edge detectors.This step is inspired by analyzing
As a common scheme of image tampering,copy-move forgery plays an important role in image forgery committee.Although several blind methods aimed at detecting replicated regions have been proposed,these
在基于激光斜射测距原理的3D扫描装置实时获取的植株3D图像中,提取二维傅里叶(2DFT)谱中直流分量作为萎蔫指数来定量研究植物的萎蔫程度,采用西葫芦、葫芦、南瓜及秋葵4种植物的嫩叶期体态变化检验了二维傅里叶萎蔫指数与萎蔫程度的相关性,结果表明:二维傅里叶谱的直流分量(萎蔫指数)与萎蔫程度具有较好的相关性,R2达到0.82以上。在此基础上,运用SPSS软件建立了二维傅里叶谱叶片萎蔫指数与环境饱和水气
This paper presents a new implementation of a high-definition image-processing engine,which mainly targets the 3-dimensional(3D)visualization and stereo video stream display of binocular display equip
In this paper,radial basis functions are used to obtain the solution of evolution equations which appear in variational level set method based image segmentation.In this method,radial basis functions
Significant high magnetic gradient field strength is essential to obtaining high-resolution images in a benchtop magnetic resonance imaging(BT-MRI)system with permanent magnet.Extending minimum wire s
Cartographic animation has been developed and widely used in geo-visualisation and many other areas in recent years.The usability of animated maps is a key characteristic affecting map users’effective
