- 本实验采用双线形插值技术进行图像的缩放。该方法输出的像素值是它在输入图像中2*2邻域采样点的平均值,它根据某像素周围4个像素的灰度值在水平和垂直方向两个方向上对其插值。在进行图像缩放时,其考虑到了相邻近的像素点间的关系。这种平均算法具有放锯齿效果,创造出来的图像拥有平滑的边缘,锯齿难以察觉,所以相对于最近邻法,其的效果比较好。在进行程序设计时,程序的输入参数为图像矩阵和结果图像的水平和垂直方向的像素数,可以忽略混叠效应。在程序运行之后可

八叉树k邻域搜索思路和数据精简
- 八叉树k邻域搜索思路和数据精简,点云数据P的K近邻指的是在物体空间内,点云数据内与P相邻的K个最近相邻点。这里采用八叉树分割法来搜索点P的K近邻。具体步骤是:先设定一个距离阈值,根据已知的P点坐标,可以求得相应的子立方体结点编号以及相邻的26个子立方体编号,每个子立方体记录下编号后,先在该子立方体内部搜索距离阈值范围内的K个近邻点,如果点数不够,则在其相邻的26个子立方体里面搜索,直到满足要求结束。
