Heavy metal accumulation and its influential factors were studied in the different land use soils, which would provide a theoretical basis for controlling the content of heavy metals in soils. To iden
开展土壤重金属空间变异规律的研究,有助于查明土壤重金属在区域空间内的变异原因、结果和趋势,揭示其空间分布规律,从而为土壤环境规划和管理提供科学依据。本文利用地统计学方法,对原阳县土壤重金属的空间变异规律进行了研究。研究表明:土壤Cu、Zn、As和Cr在东西向均无明显变异,Cu、Zn和As的变异趋势相近,在18 km范围以内各方向均无变异,主要受区域因素影响,在18 km范围以外,除东西向外均出现不
在作物生长期间,定期监测各核心示范区的土壤墒情变化情况,并根据各种作物墒情评价指标做出客观评价,提出管理建议,并以简报、网络、报纸等方式传达,以指导项目区作物的合理灌水,最终实现增产增收。
This paper presents an eye and iris detection algorithm for human facial images. The authors combine three features of the eye to develop the algorithm:1) the pixels surrounding the eyes are more vari
Pose manifold and tensor decomposition are used to represent the nonlinear changes of multi-view faces for pose estimation,which cannot be well handled by principal component analysis or multilinear a
在现今影视片头动画中,三维文字是必不可少的表现元素之一,好的文字特效可以与画面融合统一,产生较强的视觉冲击力,给人以美的享受。本文主要介绍运用3Ds Max中倒角剖面修改器与Video Post视频合成器制作三维文字及特效的方法。
Compressive sensing is a revolutionary idea proposed recently to achieve much lower sampling rate for signals.In the image application with limited resources the camera data can be stored and processe
In this paper,the edge detection for a medical image is performed based on Sobel operator,and the bounding box is obtained,by which the effective medical sub-image is extracted.Then,the centroid and t
The increasing amount of videos on the Internet and digital libraries highlights the necessity and importance of interactive video services such as automatically associating additional materials(e.g.,
For automatic object detection tasks,large amounts of training images are usually labeled to achieve more reliable training of the object classifiers;this is cost-expensive since it requires hiring pr
