代码说明:

  : 对一种基于图像几何重心的特征点提取算法进行了改进 改进后的算法可以提取任何边缘线上凹凸处的特征点 其基本 思想是,首先提取图像的边缘轮廓线,计算封闭边缘线和非封闭边缘线的几何重心 然后以重心为极点,对边缘点极坐标化,形成 幅角-极径曲线,在该曲线上寻找局部极大极小值点 最后根据局部非极大(小)抑制原则对极大(小)值点进行取舍获得特征点 模 拟结果表明算法计算简单 稳定性好 该方法提取的特征点能准确地反映目标的形状,对目标的识别 跟踪以及三维表面重建等都 具有重要的价值(This paper modifiesakindoffeatureextractingalgorithmbasedonimageedge.First, imageedgeoutlineisextracted.

  • main
    将保存有灰度图像信息的txt文件转化生成灰度图片。 txt数据只能包含数据,数据用逗号或者空格隔开,所存数据个数应与所生成的图片大小相同。例:要还原的图片大小为640*480,那么txt文件中就应当有307200个数据。(The txt file with information of grayscale image is transformed into gray image. The TXT data can only contain data, separated by commas or spaces, and the number of data stored should be the same as the size of the generated image. Example: the size of the image to restore is 640*480, so there should be 307200 data in the txt file.)
