hello, the code you use to read the ground truth of dataset is
gt_temp = cv2.imread(os.path.join(gt_path,piece+'.png'))[:,:,0] gt_temp[gt_temp == 255] = 0
why there is "[:,:,0]" for the ground truth? thank you very much! and when I use cv2 to read the ground truth of pascal voc dataset,
import cv2 import numpy as np img_cv= cv2.imread('/Users/zhangying/Desktop/2007_000129.png') img_array_cv = img_cv[:,:,0] print('use the method CV\n ',np.unique(img_array_cv))
the output is
use the method CV [ 0 128 192]
however the sum of the categories is 21 for voc dataset(128>20,192>20, is it reasonable?). How do you think about this problem? Thanks a lot!
