selecting frequency components

[Inuk Kang]

Hi, I want to know how did you select the frequency components like Figure6?
I want to select 1, 3, 6, 10 frequencies like zigzag DCT.

And, I want to know the meaning of the numbers in the layer.py.

num_freq = int(method[3:])
if 'top' in method:
    all_top_indices_x = [0,0,6,0,0,1,1,4,5,1,3,0,0,0,3,2,4,6,3,5,5,2,6,5,5,3,3,4,2,2,6,1]
    all_top_indices_y = [0,1,0,5,2,0,2,0,0,6,0,4,6,3,5,2,6,3,3,3,5,1,1,2,4,2,1,1,3,0,5,3]
    mapper_x = all_top_indices_x[:num_freq]
    mapper_y = all_top_indices_y[:num_freq]
elif 'low' in method:
    all_low_indices_x = [0,0,1,1,0,2,2,1,2,0,3,4,0,1,3,0,1,2,3,4,5,0,1,2,3,4,5,6,1,2,3,4]
    all_low_indices_y = [0,1,0,1,2,0,1,2,2,3,0,0,4,3,1,5,4,3,2,1,0,6,5,4,3,2,1,0,6,5,4,3]
    mapper_x = all_low_indices_x[:num_freq]
    mapper_y = all_low_indices_y[:num_freq]
elif 'bot' in method:
    all_bot_indices_x = [6,1,3,3,2,4,1,2,4,4,5,1,4,6,2,5,6,1,6,2,2,4,3,3,5,5,6,2,5,5,3,6]
    all_bot_indices_y = [6,4,4,6,6,3,1,4,4,5,6,5,2,2,5,1,4,3,5,0,3,1,1,2,4,2,1,1,5,3,3,3]
    mapper_x = all_bot_indices_x[:num_freq]
    mapper_y = all_bot_indices_y[:num_freq]
else:
    raise NotImplementedError
return mapper_x, mapper_y

solved. Thank you!
