otsu2018, branch master

Ensure Python 2 compatibility.

2020-07-26T10:43:12+00:00

A new class for saving and loading datasets.

This way using tqdm is optional and not a direct dependency of otsu2018.py.

Rename Clustering to Tree and make it a subclass of Node.

2020-07-25T14:42:01+00:00

Simplify and clarify PCA code.

2020-07-24T17:51:32+00:00

A script that plots the PCA decomposition.

2020-07-24T16:28:27+00:00

Use the constant illuminant by default.

2020-07-24T16:28:14+00:00

Add a simple script for computing delta E's.

2020-07-22T14:49:18+00:00

Vastly improve the quality of clusterings.

2020-07-22T14:27:50+00:00

Setting a minimum cluster size prevents the algorithm from trying to 'cheat' by creating many 3- or 4-colour clusters. This was especially bad when PCA would determine only two basis functions were necessary (the third one being essentially random), causing massive reconstruction errors.

Implement a proper progress bar and better messages.
