Generate images for 3-class classification

elboyran commented 7 years ago

Label an image as belonging to a certain class if at least 75% of the image pixels are labelled of that class.

[x] Modify function for tiling to optionally have 3 classes only (no mix).
[x] Modify script for considering only 75%-pure images for training.
[x] Modify code to also report number of images per class.
[x] Generate 5 datasets with 3 classes: Slums, BuiltUp and NonBuildUp.

The resulting images to be stored at C:\Projects\DynaSlum\Data\Kalyan\Datasets3Classes. To put on BeeHub??

Having 80% requirement for the largest images dataset (px417m250) there are only 7 images for Slum, not enough to train anything! Changing to 75%.
