SoDeep在以下三种rank-based loss中的应用 Spearman correlation: 原loss等价于 用SoDepp block替代ranking block之后得到: Mean Average Precision:关于AP(Average Precision)的定义为 得到替换后的mAP如下(这里没看懂),C为类别数量 关于mAP的相关介绍 Recall at K:在top K结果中检索出正确结果的比例。公式如下 基于...
Instance-level medical image classification for text-based retrieval in a medical data integration center A medical data integration center integrates a large volume of medical images from clinical departments, including X-rays, CT scans, and MRI scans. Ideally... KY Cheng,M Lange-Hegermann,JB H...
Image retrieval (IR) continues to be most exciting and fastest growing research areas due to significant progress in data storage and image acquisition techniques. Broadly, Image Retrieval can be Text based or Content based. Text-based Image Retrieval (TBIR) is proficient in named-entity queries ...
In this way, the text based image retrieval task can be casted as a simple nearest neighbor search of the query text representation over the outputs of the CNN over the entire image database. Our experiments demonstrate that the proposed architecture outperforms previous state-of-the-art while ...
Image retrieval has been an active research topic due to its great importance in the field of image management, digital library and web searching. However, the performances of the existing approaches, including text-based or content-based image retrieval, are often unsatisfactory. Inspired by text-...
SA用到了image->text和text->image的关系矩阵,通过提取行列,并进行相乘得到单模态的关系矩阵。表示如下: 5.4. Objective Function 一般计算损失函数的方法都是hinge-based bi-directional ranking loss,表示如下: 但是这个方式由于要把所有的negative pairs的双向损失全部加起来,因此计算上常常非常没有效率。因此,本文只...
An image retrieval algorithm based on text and semantic relevance is proposed to effectively retrieve images,which can satisfy the complex requirement of users. There are two steps in this method:images retrieval based on textual semantic relevance analysis and image extension retrieval based on SIFT ...
在Context-aware Attention部分，通过attention机制对不同信息进行非等权重处理。首先定义了基于图像和文本的attention处理方法，计算了图像和文本的相似矩阵，并通过权重矩阵进行归一化，考虑了单模态内的信息和跨模态的region与单词信息。Semantics-based attention（SA）利用了模态间的关系矩阵，通过提取行列相乘...
