At the hypothesis of big leaf, an ecosystem photosynthesis-transpiration coupling cycle model was established by the scaled SMPT-SB model from single leaf to canopy, and model parameterization methods
We constructed a coupled model for simulating plant photosynthesis and evapotranspiration (CPCEM). In the model, non-rectangular hyperbola is used to simulate leaf photosynthesis rate that is scaled u
The design of user friendly and expressive virtual brush systems for interactive digital painting and calligraphy has attracted a lot of attention and effort in both computer graphics and human-comput
In this paper we present the definition and framework of Directional Empirical Mode Decomposition (DEMD) and use DEMD to do texture segmentation. As a new technique of time-frequency analysis, EMD dec
The potential ecotoxicologial risks of methamidophos, copper, and their combinations on microbial community of black soil ecosystem in the Northeast China were assessed in species richness and structu
在利用计算机视觉技术检测苹果外部品质的过程中,苹果表面缺陷的识别相对于形状、大小、颜色的检测要复杂得多,因此缺陷检测方法的研究极具挑战性。在实验的基础上,本文对几种缺陷检测算法(“洪水法”和“蛇形法”、“自适应球形变换法”、“参考图像法”、“标准球体灰度模型法”)的思路和实验结果进行了深入的分析和比较,并对缺陷检测中尚待解决的问题进行了阐述。
研究脱落酸引发及其与植物生长调节剂的复合处理对夜香紫罗兰(Matthiolabicornis)种子萌发的效应。结果表明,将夜香紫罗兰种子于20℃下在2.5×10-5mol/L脱落酸(ABA)溶液中引发7d,能显著缩短种子平均萌发时间,增加种子萌发指数。在ABA溶液中加入吲哚乙酸(NAA)未能进一步改善夜香紫罗兰种子萌发,但其他复合处理均显著提高正常幼苗百分率。ABA和细胞分裂素(KT)及NAA复合
比较传统人工细胞形态观察和定量的操作方式,介绍了基于计算机图像处理和分析技术的有关红细胞形态特征定量的研究成果.并且展现了一套适用范围广、可作为红细胞图像的形态描述或细胞分类的图形特征参数--圆周率.同时,基于圆周率提供了一些较为适用的细胞形态特征值的算法(比如,多定位的图像获取、红细胞胞体形态的自动识别,以及对其进行的分类算法).红细胞形态的算法或程序都基于VC++,不过该程序也可运用于其他用途
