filter_tiles(tesselation, coordinates, filter_threshold)
tesselation |
data.frame output from the deldir function |
coordinates |
data frame with original coordinates |

numeric describing the quantile threshold value to use for area filtering |
Here we want to filter based on the size of the tile under the assumption that very large tiles are probably due to unpexted space. The issue is that if you don't apply this threshold, subtle pixel patterns are lost wuhtin the sea of pixels. If the ueser really dont want to filter anything out then you don't We will set a filter threshold pretty high though to make sure that it does get filter out as default.
