Abstract

Weakly-supervised semantic segmentation (WSSS) is introduced to narrow the gap for semantic segmentation performance from pixel-level supervision to image-level supervision. Most advanced approaches are based on class activation maps (CAMs) to generate pseudo-labels to train the segmentation network. The main limitation of WSSS is that the process of generating pseudo-labels from CAMs which use an image classifier is mainly focused on the most discriminative parts of the objects. To address this issue, we propose Puzzle-CAM, a process minimizes the differences between the features from separate patches and the whole image. Our method consists of a puzzle module (PM) and two regularization terms to discover the most integrated region of in an object. Without requiring extra parameters, Puzzle-CAM can activate the overall region of an object using image-level supervision. In experiments, Puzzle-CAM outperformed previous state-of-the-art methods using the same labels for supervision on the PASCAL VOC 2012 test dataset.

  • performance issue

    performance issue

    When I used the released weights for inference phase and evaluation, I found that the mIoU I got was different from the mIoU reported in the paper. I would like to ask whether this weight is corresponding to the paper, if it is, how to reproduce the result in your paper. Looking forward to your reply.

  • Evaluation in classifier training is using supervised segmentation maps?

    Evaluation in classifier training is using supervised segmentation maps?

    Hello, thank you for the great repository! It's pretty impressive how organized it is.

    I have a critic (or maybe a question, in case I got it wrong) regarding the training of the classifier, though: I understand the importance of measuring and logging the mIoU during training (specially when creating the ablation section in your paper), however it doesn't strike me as correct to save the model with best mIoU. This procedural decision is based on fully supervised segmentation information, which should not be available for a truly weakly supervised problem; while resulting in a model better suited for segmentation. The paper doesn't address this. Am I right to assume all models were trained like this? Were there any trainings where other metrics were considered when saving the model (e.g. classification loss or Eq (7) in the paper)?

  • error occured when image-size isn't 512 * n

    error occured when image-size isn't 512 * n

    dear author: I notice that if the image size isn't 512 x 512, it will have some error. I use image size 1280 x 496 and i got tensor size error at calculate puzzle module:the original feature is 31 dims and re_feature is 32 dims. So i have to change image size to 1280 x 512 and i work. So i think this maybe a little bug. It will better that you fixed it or add a notes in code~ Thanks for your job!

    the backbone of Affinitynet is resnet38. Why did you write resnet50?

    In Table 2 of your paper, the backbone of Affinitynet is resnet38. Why did you write resnet50? After my experiment, I found that RW result reached 65.42% for Affinitynet which is based on resnet50 and higher than yours.

  • Ask for details of the training process！

    Ask for details of the training process！

    I am trying to train with ResNest101, and I also added affinity and RW. When I try to train, it runs according to the specified code. It is found that the obtained affinity labels are not effective, and the effect of pseudo_labels is almost invisible, which is close to the effect of all black. I don't know where the problem is, who can explain the details. help!
