中文说明：特征提取的基于它们从输入图像的几何性质的英语语言的单个字符。两种方法进行阐述以供提取特征向量。为我的目的生成的最后特征向量有 120 多个元素。功能基于基本的几何形状组成的单个字符。它计算在给定的字符有多少基本线段。基本线段喜欢水平、 垂直和对角线是什么寻找。它们的长度和面积归一化到整个图像被用作功能。在图像中的孔的数量是另一种功能。类似的属性用于特征提取。
English Description：
The features extraction of single characters of english language based on their geometric properties from the input image. Two approaches are explained for extracting feature vectors. The final feature vector generated for my purpose had more 120 elements. The features are based on the basic geometric shapes that comprises a single character. It calculates how many basic line segments are there in the given character. Basic line segments like horizontal, vertical and diagonal are what looked for. Their length and area normalized to the entire image are used as features. The number of holes in a image is another feature. SImilar properties are used for feature extraction.
