TiledColorBasedDistance¶

Qualified name: CDC.tiled_color_based_distance.TiledColorBasedDistance

class TiledColorBasedDistance(*, ortho_tiler, color_model, scale, output_location)[source]¶

Calculate color based distance on tiled orthomosaic.

Parameters:

ortho_tiler (OrthomosaicTiles) – An instance of OrthomosaicTiles
color_model (BaseDistance) – The color model to use for distance calculations. See color_models
scale (float) – A scale factor to scale the calculated distances with.
output_location (pathlib.Path) – Where output orthomosaic and tiles are saved.

Methods

`convertScaleAbs`	Scale image by alpha and take the absolute value.
`process_tiles`	Calculate color based distance on all tiles and save output.
`save_statistics`	Calculate a histogram of the color based distance from all tiles.

static convertScaleAbs(image, alpha)[source]¶

Scale image by alpha and take the absolute value.

Parameters:

Return type:

ndarray

process_tiles(save_tiles=False, max_workers=4)[source]¶

Calculate color based distance on all tiles and save output.

Parameters:

save_tiles (bool) – Save all tiles to output_location.
max_workers (int | None) – Maximum number of threads to use for processing.

Return type:

None

save_statistics(args)[source]¶

Calculate a histogram of the color based distance from all tiles. Save histogram in output_location/statistics with a txt file of metadata.
