WatershedSegmentation1
- 分水岭分割对图像特征使用梯度下降法和沿区域边界分析弱点(weak points) 来将像素分 类为区域。想像在一个有水流动的拓扑地形结构中,水在重力的引导下聚集到一个地势较低 的盆地。随着水量的增加,水将流满整个盆地直到水流溢出到另一个盆地,这样就会将一些 小盆地吞没形成大的盆地。使用局部的几何结构来形成区域(集水的盆地),在图像领域中正 如使用一些诸如曲率或梯度强度等特征中的局部极值来将像素连接成区域。这种技术不像其 他区域分割,它几乎不需要用户定义门限,尤其适合对以不同的
SIFT-matlab
- SIFT算法大致有四个步骤: 1,尺度空间极值检测。在尺度空间通过高斯微分函数来检测潜在的对于尺度和旋转不变的兴趣点。 2,关键点定位。在兴趣点位置上,确定关键点的位置和尺度。 3,方向确定。基于图像局部的梯度方向,给每个关键点分配方向。 4,关键点描述。在每个关键点的领域内测量图像局部的梯度。最终用一个特征向量来表达。 -SIFT算法大致有四个步骤: SIFT algorithm has four steps: 1,尺度空间极值检测。在尺度空间
