Train

(Back to top)

python train.py --img-dir "[train dataset dir]" --batch-size 64 --img-size 32 --epoch 20

Test

(Back to top)

python test.py --nomal-dir "[test normal dataset dir]" --abnormal-dir "[test abnormal dataset dir]" --view-img --img-size 32

Example : Train dataset : factory line only

dataset :factory line , top: input images, bottom: reconstruct images

dataset :factory noline , top: input images, bottom: reconstruct images

Lose-value-distribution

(Back to top)

Blue : normal dataset

Orange : abnormal dataset
