  • RGB <-> BGR

    RGB <-> BGR

    From this line, I assume you use RGB: img = img - np.array([104,117,123])

    However opencv uses BGR, so this line returns BGR: if args.path=='CAMERA': ret, img = cap.read()

    Then BGR is fed to the network bboxlist = detect(net,img)

    I fed RGB to the network and got worse results. Is it possible that you meant RGB in all places but the network is actually trained for BGR? (If then it should be img = img - np.array([123,117,104]))

  • How Convert Weights

    How Convert Weights

    Dear @clcarwin, Thank you for your nice work. Would you please tell me how you can convert Caffe weights and model of S3FD into PyTorch? Can you convert the model & pre-trained weights of RefineDet into PyTorch?

  • evaluation accuracy is not good as the original paper

    evaluation accuracy is not good as the original paper

    hi @clcarwin,

    I test you evaluation results on wider face as (easy 92.8, medium 91.5, hard 84.2). But with the original model provided by sfzhang15/SFD, I can get (easy 93.8, medium 92.4, hard 85.1).

    Did I test correctly? If so, why there is accuracy loss?

    Great work! Best,

    'float' object cannot be interpreted as an integer??

    Sir,I'm sorry to disturb you about this object. I run this object on windows 10,python 3.5.2 ,pytorch 0.3. After : python test.py --model data/s3fd_convert.pth --path data/test01.jpg, the screen display: D:\Python\Pytorch_cw_sfd\SFD_pytorch>python test.py --model data/s3fd_convert.pth --path data/test01.jpg Traceback (most recent call last): File "test.py", line 71, in bboxlist = detect(net,img) File "test.py", line 27, in detect for i in range(len(olist)/2): olist[i2] = F.softmax(olist[i2]) TypeError: 'float' object cannot be interpreted as an integer

    Why ???

  • padding size of fc6

    padding size of fc6

    Hi @clcarwin,

    Why do you set the padding size of fc6 to 3? This is inconsistent with the original paper. See https://github.com/clcarwin/SFD_pytorch/blob/master/net_s3fd.py#L42

    Best,

  • Optimization

    Optimization

    Good: It is accurate.

    Bad: The inference time is more than 80 ms for realtime usage. To make it work for realtime image has to be resized to less than 200x200 which reduces accuracy.

    So in order to make it usable the only way is to make it faster. Have you tried using TensorRT or TVM or Pytorch serving in C++ ?

  • Several speed & code updates

    Several speed & code updates

    Seems nobody's looking at PR's here, but letting others know I've made a number of improvements.

    It runs smoothly on modern pytorch (1.3) and refactored the code to eliminate redundant code. I also added some convenient methods that make it easier to do common things, like detect_faces. Also, added integration tests.

    I independently found the same speed-up as @kir-dan in https://github.com/clcarwin/SFD_pytorch/pull/4 and moved all that code into pytorch instead of numpy, so it can be fully run on GPU.

    Very high GPU memory usage

    Hi, I have been running the model using test.py and modified it run multiple files. The GPU memory keeps on increasing,from 3gigs to 9 gigs. Is this due to poor garbage collection?

    Change Anchor Boxes Aspect Ratio

    Dear @clcarwin, If one wants to change the aspect ratio of anchor boxes, must just changed the detect method in test.py? For example, line https://github.com/clcarwin/SFD_pytorch/blob/96fdfbe22eef176a04802d915834b82a131a854d/test.py#L39 or other methods moreover must changed?
