News!

2024/04/25 : Update the training code! 😊

Dataset

1. MVTEC AD
2. BTAD
3. KSDD2

   Due to the non-square ksdd2 image , it need to crop the image of KSDD2 samples.

   Preprocess code in this.

Env Install

We follows ControlNet.

Prepare

Build trainset for AdaBLDM training.

MVTec-AD in this.

BTAD in this.

KSDD in this.

Train

Mvtec-AD Part

0. Download Mvtec-AD dataset.
1. Foreground_predictor : Look this
2. Prepare for mvtec dataset : Look this
3. Download SD model : download "v1-5-pruned.ckpt". And put it on the directory named "./models".
4. Convert weight of sd model :

   python tool_add_control.py ./models/v1-5-pruned.ckpt ./models/control_sd15_ini.ckpt

5. Config training setting : Look this
6. Start to train a AdaBLDM:

   # default : train a hazelnut with hole.
   python train.py

Test

0. Input the model checkpoint : in test.py line 35.
1. Run code:

   # default : test with hazelnut with hole.
   python test.py

Stable Diffusion

Pretrain Stage

How to obtain the mvtec object's description? Look at this.

Foreground_predictor for trimap

How to get the object's foreground ? Look at this

SVM
