@huxianxian I am afraid I have no clue on this problem since I have already tested the forward and gradient pass comparing to the original implementation. But still, I am curious about two questions concerning this problem:
Thanks, Yes ,I visualize the offset with the script from original implementation , and the offset is got from your other repo : https://github.com/Zardinality/TF_Deformable_Net . I have successfully run your code for TF_Deformable_Net on VOC dataset.I get the following results: Mean AP = 0.6289
Results:
0.708
0.697
0.645
0.475
0.448
0.661
0.792
0.783
0.374
0.634
0.566
0.695
0.716
0.683
0.755
0.363
0.593
0.612
0.760
0.616
0.629
Then i try to make a visualize for deform conv with the trained model , I got the offsets with the following code:
cls_score, cls_prob, bbox_pred, rois , a_offset,b_offset,c_offset, = \
sess.run([net.get_output('cls_score'), net.get_output('cls_prob'), net.get_output('bbox_pred'),net.get_output('rois'),
net.get_output('res5a_branch2b_offset'),net.get_output('res5b_branch2b_offset'),net.get_output('res5c_branch2b_offset'),],feed_dict=feed_dict)
all_offsets=[a_offset,b_offset,c_offset]
The I visualize the offsets with the script from original implementation,
res5a_offset = all_offsets[0] res5b_offset = all_offsets[1] res5c_offset = all_offsets[2]
im = im[:, :, (2, 1, 0)]
show_dconv_offset(im , [res5c_offset, res5b_offset, res5a_offset])
the function show_dconv_offset(im , [res5c_offset, res5b_offset, res5a_offset]) is the script from original implementation. but I can't get the correct results.
show_dconv_offset
by default uses a step of [2,2]
, is it relevant to your issue since in Resnet101_train.py
we use stride=1
?
Thanks for your amazing work. Have you ever tried to visualize the deformable convolution just like the results in the paper 'Deformable Convolutional Networks'? like this: I made a try to visualize your deformable convolution code. But I get the following results: Can you help me?
