To set up point thinning, you select the type of points you want to thin, how you want to dispose of the points designated for removal, and then define the grid by which to divide the image into cells. By defining the grid, you can specify the how many points you want to retain in each cell.
To set up point thinning
For example, with an image that has an aspect ratio of two to one (2:1), and you want to indicate that the short side has 10 cells (and, therefore, the long side has 20 cells), enter 10. That is, the image has 200 cells.
That is, the value is used in conjunction with the value of Number of cells on short side of each image to determine how many points to retain per cell.
