This study proposed a new method for extracting multiple cropping index on pixel level with multi-temporal moderate-resolution imaging spectroradiometer enhanced vegetation index data based on the crop phenology and decision tree. The method could be divided into two steps.

该文通过深入分析农作物的农时历和耕地的时间序列植被指数曲线的对应关系，提取了反映作物种植模式的特征时相，并以特征时相的EVI值作为特征参量，构建了提取耕地复种指数的决策树方法。

An effective filtering algorithm, by comparing the particular pixel within the region to the neighborhood mean filter for image denoising.

详细说明：一种有效的滤波算法，通过比较特定区域内的像素点的邻域均值来进行图像的去噪滤波。

The intensity of pulse noisy pixels significantly differs from adjacent pixels of image. The de-noising will be accomplished by modifying the intensity of the noisy pixel according to the firing patterns of adjacent neurons of PCNN. At last, this dissertation suggests a new kind of filter for de-noising pulse noise based on the PCNN and median filter. It is very simple, and the simulation experiment of the image processing shows that the de-noising effect is much better than neighborhood averaging method and median filter.

一般脉冲噪声点与其所在图像像素灰度值之间相关性很差，而PCNN脉冲耦合神经网络能使相似神经元同步激发；这就决定亮点脉冲噪声像素对应神经元会在其区域所在相邻神经元中首先激发，为此结合中值滤波，我们提出了结合PCNN脉冲耦合神经网络和中值滤波的混合滤波新算法，理论分析和实验证明，该方案在滤除噪声的同时，比常规中值滤波更有效地保持了图像的高频细节信息。

In this progress, the order of the picture is non-linear and the picture pixel is discrete.

在这过程中，画面次序是非线性的，画面像素是离散的。

For this reason, make sure that the bitmap has a 2 pixel white border around any non-white pixels.

因此，位图中在非白色区域的周围一定要有2个像素的白色边界。

Secondly, According to the sub-pixel structure characteristic, the potential of deriving vegetation fraction from normalized difference vegetation index using the TM data and resorting to "Dense Vegetation Model" and "Nondense Vegetation Model", is studied in an area in the south of Yichang.

本文首先对TM影像进行了几何纠正、辐射校正、大气校正；然后根据混合像元的结构特征，利用TM数据从植被指数中采用"等密度模型"和"非密度模型"提取了宜昌南部地区的植被覆盖度。

By the minimum risk Bayes decision theory, this paper develops a new way of image segmentation: establish the mathematics model of image segmentation; estimate the probability density of grey scales and figure out its math-expectation and square difference that accord with normal distribution and the loss function; and judge the every pixel dot in the image according to the minimum risk Bayes decision theory and determine whether it is of target or non-target images, thereby realizing the extraction of the target image.

依据最小风险贝叶斯决策理论，提出了一种基于最小风险贝叶斯决策的图像分割方法。首先建立图像分割的最小风险贝叶斯决策模型，对灰度级类条件概率密度估计出其符合正态分布的数学期望和方差以及损失函数，再依据最小风险贝叶斯决策理论对图像中的每一像素点进行目标图像和非目标图像的类别判断，从而实现目标图像的提取。
