Previous research in weakly supervised instance segmentation has explored various approaches to the ultrasound image segmentation work for a real-time medical system8. However, fully supervised instance segmentation models, while highly effective, require extensive labeled data to achieve their potential, ma...
2.4 Weakly Supervised Instance Segmentation 直接计算得分进行排序和NMS。在生成的proposal基础上(~~生成方式未明示~~),分别从实例、边界和类别信息三个角度均衡。 3. Experiment Ablation Study 在VOC2012上的实验,轮廓边界的影响相对不大;背景和实例关注部分影响大;PS次之。在VGG-16提升更大,很明显因为本来特征...
Peak Stimulation(峰值激活)---产生CPM(类峰值图) 2. Peak Back-propagation (峰值反向传播)---产生PRM(峰值响应图) 3.Weakly Supervised Instance Segmentation(弱监督实例分割) 一、第一个过程 :Peak Stimulation(峰值激活)---产生CPM(类峰值图) 输入一张图片到全卷积分类器中,得到20个通道的特征图(源代码...
推理阶段时,已确定的极值点会反向传播去产生每一个实例的高信息区域,称为PRMs(Peak Response Maps),PRM提供具有良好细节的有关每一个实例的代表,进一步会生成分割掩码, 3.1全卷积结构 通过直接去除全局池化层,将全连接层变为1*1卷积层,现代神经网络分类器就变成了全卷积网络,在前向传播中保留着空间信息,第一步...
Consequently, weakly supervised instance segmentation (WSIS) and semi-supervised instance segmentation (SSIS) methods have received increasing attention to reduce annotation costs. In weed detection, the scarcity of fully annotated weed datasets hinders the potential application of deep learning models in ...

Weakly Supervised Segmentation with TensorFlow This repo contains a TensorFlow implementation of weakly supervised instance segmentation as described in Simple Does It: Weakly Supervised Instance and Semantic Segmentation, by Khoreva et al. (CVPR 2017). The idea behind weakly supervised segmentation is to...
Because the HPACellSegmentator was provided, some participants turned this competition into object detection while others considered it as weakly supervised semantic segmentation. As with any other machine learning work, the winning models carry the bias of the training data, and the performance in ...
