# Train
|
|
just run: python train.py with config_params.json
|
|
|
|
|
|
# Ground truth format
|
|
|
|
Lables for each pixel is identified by a number . So if you have a
|
|
binary case n_classes should be set to 2 and
|
|
labels should be 0 and 1 for each class and pixel.
|
|
In the case of multiclass just set n_classes to the number of classes
|
|
you have and the try to produce the labels
|
|
by pixels set from 0 , 1 ,2 .., n_classes-1.
|
|
The labels format should be png.
|
|
|
|
If you have an image label for binary case it should look like this:
|
|
|
|
Label: [ [[1 0 0 1], [1 0 0 1] ,[1 0 0 1]],
|
|
[[1 0 0 1], [1 0 0 1] ,[1 0 0 1]] ,
|
|
[[1 0 0 1], [1 0 0 1] ,[1 0 0 1]] ]
|
|
This means that you have an image by 3*4*3 and pixel[0,0] belongs
|
|
to class 1 and pixel[0,1] to class 0.
|
|
|
|
# Training , evaluation and output
|
|
train and evaluation folder should have subfolder of images and labels.
|
|
And output folder should be empty folder which the output model will be written there.
|
|
|
|
# Patches
|
|
|
|
if you want to train your model with patches, the height and width of
|
|
patches should be defined and also number of
|
|
batchs (how many patches should be seen by model by each iteration).
|
|
In the case that model should see the image once, like page extraction,
|
|
the patches should be set to false.
|
|
# Pretrained encoder
|
|
Download weights from this limk and add it to pretrained_model folder.
