You need to make two folders
- Images Folder - For all the training images
- Annotations Folder - For the corresponding ground truth segmentation images
The filenames of the annotation images should be same as the filenames of the RGB images.
The size of the annotation image for the corresponding RGB image should be same.
For each pixel in the RGB image, the class label of that pixel in the annotation image would be the value of the blue pixel.
Example code to generate annotation images :
import cv2
import numpy as np
ann_img = np.zeros((30,30,3)).astype('uint8')
ann_img[ 3 , 4 ] = 1 # this would set the label of pixel 3,4 as 1
cv2.imwrite( "ann_1.png" ,ann_img )Only use bmp or png format for the annotation images.
