These above problems, which are very important and valuable in agricultural crops area monitoring, are currently less researched. Hence, in this paper, seven types of common texture and five vegetation indices were respectively added into TM multispectral bands to classify using three different methods, which are Minimum Distance, Maximum Likelihood and Support Vector Machine, and analyze the effect on winter wheat identification accuracy by comparing the classification results. The contexture include Mean, Variance, Homogeneity, Contrast, Dissimilarity, Entropy, Variance, Angular Second Moment and Correlation, and the vegetation indices are RVI, SAVI, RDVI, NDWI and SLAVI.
为此，该文将平均值、方差、均一性、反差、相异性、熵、角二阶矩、灰度相关7种纹理信息以及比值植被指数、土壤调整植被指数、重归一化植被指数、植被液态水含量指数、有效叶面积植被指数5种植被指数信息分别加入到TM多光谱数据中，同时还进行了最佳波段选择，利用最小距离、最大似然和支持向量机3种方法进行分类提取小麦，研究了不同特征信息对小麦测量精度的影响。

First scanning the known handwriting materials then number them ,In pretreatment, we convert the valid part of the image into a standard size, as images carries out duotone and go throw off chirp handling in order to achieve better effect.draw features from the known handwriting materials with the Co-occurence,especially,we divided a copy of handwriting into 25 little pieces with the size of 128*128 ,drawing features from every little piecese with four directions(0 degree, 45 degrees, 90 degrees as well as 135 degrees) and calculate the four major feature values( veins and the statistical quantity of veins contrast and the statistical quantity of veins consistency Shang the statistical quantity of statistical quantity as well as the veins correlation of gray scale ), preservation all the feature value that drawn from all known ma terials to the handwriting characteristic database,then input the unknown handwriting materials, also using the method of the Co-occurence to draw those features, recycling the minimum European Distance law match the unknown writing material feature value with the handwriting characteristic feature database, export the label of the known hand writing materials which is most similar to the unknown material with minimum European Distance, and then we can confirm who is the author of the unknown material.
首先将笔迹材料作为图象扫描输入，并对其进行编号。预处理部分可将笔迹图象的有效部分规范化到一个统一尺寸，接着对其进行二值化和去除噪声的处理，以便于更好的提取图像的特征。在此我们采用了灰度共生矩阵法提取手写笔迹材料的纹理特征，与以往有所不同的是，我们将一份手写材料分割成64块大小为80*80象素的子图象，每个小块都从四个方向（0度、45度、90度以及135度）来更全面的提取特征，并计算出四个最主要的特征值（纹理一致性的统计量、纹理反差的统计量、纹理熵的统计量以及纹理灰度相关性的统计量），将从所有已知材料提取的特征值保存到纹理特征库中，对于待检手写材料，同样采用灰度共生矩阵的方法提取其纹理特征，再利用最小欧氏距离分类法将从待检手写材料中提取的特征值与纹理特征库中的特征值进行比对，与欧氏距离比对值最小的相匹配，输出匹配成功的原材料的标号，进而识别出待检材料书写者的身份。

We jumped out of the taxi in haste and tried to take photos as many as we can. In this place, the colour for us is too white to open eyes and is too blue to feel blue. However, when we walked further, we found there were some people wearing the long-sleeve clothes, trousers, face mask, and hats working hard under the burning sun (The average temperature should be more than 40C). A huge contrast was formed between their quiet work figures and our high jinks. If there is any silent time in the world, it may be the moment.
我们迫不及待的跳下车，在这白到眼睛快睁不开，蓝到心情应该不再 blue 的地方尽情拍照，然而当越走越靠近内陆，我们发现远方有身著长袖长裤、头戴帽子、脸带面罩，把全身上下都包裹很好的一群人，正在烈日(平均温度应该有 40 度 C 以上吧)下拿著铲子、挥舞著锄头辛苦的工作著，他们默默劳动的身影与一旁嘻笑玩乐的我们形成极大的反差，如果说这个世界有沉默的时候，也许就是在这一刻吧！

The results showed that there were significant differences among parameters of texture feature of the different land utilization. In the desertification, the mean and variance were comparatively high. The gray level was asymmetry, the contrasts between neighboring pixels were significant; while in water and irrigable land, the mean, variance was a little bit low, the grey level was symmetry; the mean, variance and gray level in the forest and dry land was between the above (desertification and water and irrigable land).
不同土地利用类型之间纹理特征参数差异明显，荒漠化土地的均值、方差值较高，灰度分布不均匀，相邻像元反差明显，内部变化剧烈；水体和灌溉耕地的均值、方差值很低，灰度值均匀，内部变化小；林地和旱耕地信息介于上述两类土地之间。
