基于认知科学以及《Prototypical Networks for Few-shot Learning》中的PN的原型理论,作者模仿之前的使用双分支架构,提出了一种小样本语义分割框架。双分支的第一分支是原型学习器,从support set中提取出对应各个类的原型特征向量;第二分支是分割网络,他将图片与原型特征向量作为输入,并且输出segmentation mask。 figure....

For one-shot segmentation, prototype learning is extensively used. However, using only one RGB prototype to represent all information in the support image may lead to ambiguities. To this end, we propose a one-shot segmentation network based on multi-modal prototype learning that uses depth ...
Existing polyp segmentation models from colonoscopy images often fail to provide reliable segmentation results on datasets from different centers, limiting their applicability. Our objective in this study is to create a robust and well-generalized segmentation model named PrototypeLab that can assist in ...
We design business and experience prototypes to facilitate learning from stakeholders and customers. A design-led approach that informs business decisions, supports product development and results in happier customers.
Semantic segmentation models have two fundamental weaknesses: i) they require large training sets with costly pixel-level annotations, and ii) they have a static output space, constrained to the classes of the training set. Toward addressing both problems, we introduce a new task, Incremental Few...
Semantic segmentation models comprise an encoder to extract features and a classifier for prediction. However, the learning of the classifier suffers from the ambiguity which is caused by two factors: (1) the weights of a classifier for similar categories may have positive similarities lowing the pe...

接下来首先介绍在线聚类的算法,基于在线聚类结果,介绍提出的两个新的metric learning的训练目标。 聚类是对每个类别单独进行的处理,前两个约束保证每个c类内的像素点只能匹配到一个prototype,第三个约束是鼓励所有的像素点均匀匹配到各个prototype,避免许多个像素点几乎都匹配到同一个prototype上了。此外作者还为了快速求...
