Please check the intermediate results (part_xxx.raw) of the crowd mask.

Our translation code is shown below:

dst_file = os.path.join(mask_folder,preprocess_file[0:10]   '.png')
if not os.path.exists(dst_file):
    mask = np.fromfile(os.path.join(root_path, i_scene, i_type, preprocess_file), 'uint8').reshape(1080, 1920)*255               
    mask = Image.fromarray(mask)
    # pdb.set_trace()
    mask.save(dst_file)

Thank you for your reply. I read the part_xxx.raw and try to show it,

raw_path = 'D:/GAME/Steam/steamapps/common/Grand Theft Auto V/data/part_1_0/1558631488/part_0.raw'

mask = np.fromfile(raw_path,dtype='uint8').reshape(1440, 2560) * 255

# matplotlib
plt.imshow(mask, cmap='gray')
plt.show()

# PIL.Image
mask = Image.fromarray(mask)
mask.show()

The result is same as before:

Do you create and save the .raw file in main.cpp? I'm looking at your source code.

part_xxx.raw contains many types of objects, I think you should show it using a color mask instead of a gray image.
in order to get the crowd mask from part_xxx.raw file, we analyze the stencil and select the specific indices, which is shown in function getCurve of combine.py. I think this file maybe help you debug your code.

The white region is minimap, which is at the top layer of *.raw file.

So the solution is close minimap when running GCC-Collector.

@Elin24 I do not think the map disturbs the raw file. In our generation process, some images also contain map region but the crowd mask seems to be correct.

I close the minimap and it works. Thank you all @gjy3035 @Elin24

Hi guys , why I'm getting a balck image, I just want to generate images with people masked..
I really appreciate it if anyone could reply.
