| OSP-15 | CDSP: Scribble Hides Class: Promoting Scribble-Based Weakly-Supervised Semantic Segmentation with Its Class Label
| Date Created Owner Implement in | In this study, we propose a class-driven scribble promotion network, which utilizes both scribble annotations and pseudo-labels informed by image-level classes and global semantics for supervision. Directly adopting pseudo-labels might misguide the segmentation model, thus we design a localization rectification module to correct foreground representations in the feature space. This work has been accepted by AAAI2024. | Repository License Related Paper |
| OSP-14 | RD3D: 3-D Convolutional Neural Networks for RGB-D Salient Object Detection and Beyond
| Date Created Owner Implement in | We propose to disentangle the conventional 3-D convolution into successive spatial and temporal convolutions and, meanwhile, discard unnecessary zero padding. This eventually results in a 2-D convolutional equivalence that facilitates optimization and reduces parameters and computation costs. Thanks to such a progressive-fusion strategy involving both the encoder and the decoder, effective and thorough interactions between the two modalities can be exploited and boost detection accuracy. The related work has been published by IEEE Transactions on Neural Networks and Learning Systems. | Repository License Related Paper |
| OSP-13 | One-Pot Multi-Frame Denoising
| Date Created Owner Implement in | In this paper, we propose a novel unsupervised learning strategy called one-pot denoising (OPD), which is the first unsupervised multi-frame denoising method. We provide two specific implementations, namely OPD-random coupling and OPD-alienation loss, to achieve OPD during model training based on data allocation and loss refine, respectively. The related work has been published by International Journal of Computer Vision. | Repository License Related Paper |
| OSP-12 | BCAM: Background-Aware Classification Activation Map for Weakly Supervised Object Localization
| Date Created Owner Implement in | Our work proposes a novel mechanism called the background-aware classification activation map (B-CAM) to add background awareness for WSOL training. Besides aggregating an object image-level feature for supervision, our B-CAM produces an additional background image-level feature to represent the pure-background sample. This additional feature can provide background cues for the object classifier to suppress the background activations on object localization maps. Moreover, our B-CAM also trained a background classifier with image-level annotation to produce adaptive background scores when determining the binary localization mask. The related work has been published by IEEE Transactions on Pattern Analysis and Machine Intelligence. | Repository License Related Paper |
| OSP-11 | DEMCR: Discriminative ensemble meta-learning with co-regularization for rare fundus diseases diagnosis
| Date Created Owner Implement in | In this work, we develop an automatic diagnosis system for rare fundus diseases, based on the meta-learning framework. The system incorporates a co-regularization loss and the ensemble-learning strategy into the meta-learning framework, fully leveraging the advantage of multi-scale hierarchical feature embedding. We initially conduct comparative experiments on our newly-constructed lightweight multi-disease fundus images dataset for the few-shot recognition task (namely, FundusData-FS).

| OSP-10 | BagCAMs: Bagging Regional Classification Activation Maps for Weakly Supervised Object Localization
| Date Created Owner Implement in | This paper elaborates a plug-and-play mechanism called BagCAMs to better project a well-trained classifier for the localization task without refining or re-training the baseline structure. Our BagCAMs adopts a proposed regional localizer generation (RLG) strategy to define a set of regional localizers and then derive them from a well-trained classifier. This work has been accepted by ECCV2022. | Repository License |
| OSP-09 | CCLD-Net: Boosting medical image segmentation via conditional-synergistic convolution and lesion decoupling

| OSP-07 | BLRM: Bayesian Statistics Guided Label Refurbishment Mechanism
| Date Created Owner Implement in | In this work, we proposed a novel Bayesian statistics guided label refurbishment mechanism (BLRM) for DNNs to prevent overftting noisy images. BLRM utilized maximum a posteriori probability (MAP) in the Bayesian statistics and the exponentially time-weighted technique to selectively correct the labels of noisy images.
