Save a sliced point cloud- Matlab

Question

I have sliced a point cloud(30%) from original cloud(.ply image) using Matlab R2015b Image Processing Toolbox. When i save that sliced cloud as a new point cloud.

sliced and background of original both are saved. How can i just store sliced part as a new point cloud (.ply)

stepSize = 1;
indices = 1:stepSize:(cloudImage.Count)/2;
pt = select(cloudImage, indices);
pcwrite(cloudSliced,'half','PLYFormat','binary');

Answer 1

From your code it appears that the sliced point cloud is stored in pt. So it should be

pcwrite(pt,'half','PLYFormat','binary');
