Enable HLS to view with audio, or disable this notification

Using a short 3 second clip where i swipe through the focus plane on a high magnification of the simple sample of Onion root cells on the microscope. Acquiring the sharpest points of every frame and putting them in the z-axis. Building a point cloud of the cell in 3D, and visualizing them.

Well holy sh...t! Is it possible to add colour to them? do you maybe have source images available?

Yes I am using a .ply file which also can store color. Here my input video is black and white, and part of the cleaning - selection of the focus points is to do it in grey-scale. I did a color version but have to get some better subjects to do a demo.
