Threshold-segmentation

说明：  边缘检测技术用于医学图像的边缘检测， 对特定目标分割前做边缘定位(objective edge detectiong for medical AI platform.)

说明：  相机是将三维世界坐标系中的坐标点映射到二维图像平面的过程能够用一个几何过程描述，最简单模型称为针孔模型。 因为相机镜头透镜的存在，使得光线投影到成像平面过程中产生了畸变。(Camera is the process of mapping coordinate points in three-dimensional world coordinate system to two-dimensional image plane, which can be described by a geometric process. The simplest model is called pinhole model. Because of the existence of camera lens, the light rays are distorted when they are projected onto the image plane.)

对圆形物体图像进行图像边缘检测，图像分割，检测及圆拟合(Images of circular objects in image edge detection, image segmentation, detection and circle fitting)

gdal读tiff图像,获取图像大小，波段信息，图像数据，写Tiff图像到固定路径。(Read and write an TIff image using GDAL)

计算图像处理中的评价指标NPCR和UACI(Calculate the evaluation indexes NPCR and UACI)

图像检测，目标检测简单来说就是找出图像中的目标并给定目标的位置，一般用矩形框定位出目标(In image detection, target detection is simply to find out the target in the image and give the location of the target. In general, the rectangular box is used to locate the target)

matlab源文件，可以实现利用matlab来画各种饼图，显示直观，对做数据分析和论文的同志会有帮助。(matlab source files, can be achieved using matlab to draw a variety of pie, intuitive display, and to do data analysis and papers comrades would help.)

说明：  均值比差异图生成，用于SAR图像变化检测，生成差异图(mean ratio difference map generation, used for SAR image change detection, generate difference map)
