Through establishment of a test set including four languages, an identification effect of the text-image similarity-degree measurement method is tested and by application of recall ratio, precision ratio and an F value, an effect of the method is measured and a result turns out that the recall...
我们使用两个互补的指标对这些结果进行数值评估:文本-图像 CLIP余弦相似度(text-image CLIP cosine similarity),用于量化生成的图像与文本提示的符合程度(越高越好),以及 DINO-ViT 自相似度(DINO-ViT self-similarity)[46] 之间的距离,量化结构保存的程度(越低越好)。 正如在图 9 中所见,我们的方法通过实现结构...
R-prec在COCO图像上通常会失败,因为在COCO图像中,可能会将高度相似性分配给提到全局背景色的错误标文本描述或出现在中间的对象。 五、VS相似度(Visual-Semantic Similarity) 5.1、原理 VS相似度通过一个经过训练的视觉语义嵌入模型计算图像和文本之间的距离来衡量合成图像和文本之间的对齐。具体来说,学习两个映射函数,...
两个Encoder输出的特征经过线性层映射到同一个联合语义空间后,采用cosine similarity计算图文相似度。它的主要贡献是:提出在训练阶段使用hardest negative triplet loss,即:只考虑mini batch中和目标最相似的样本的计算triplet loss,而不是目标样本之外的全部样本。实验结果证明,取max的方法比传统sum的方法要更好。
Accordingly, a Text-Image Similarity Database (TISDB) consisting of 615.6k text-image pairs of English characters, Chinese characters, and Arabic numbers was established. Extensive experiments were conducted to demonstrate that our TimNet outperforms existing state-of-the-art methods. 展开 ...
A brief review of existing Image Retrieval Systems is provided, hilighting a major drawback of these prototypes, namely the lack of integration between classical ``semantic search'', and visual similarity retrieval (i.e. content-based retrieval). A new approach is proposed, that tries to ...
Deep Attentional Multimodal Similarity Model DAMSM学习了两个神经网络(text encoder-LSTM,image encoder -CNN),将图像的子区域和句子中的词映射到同一个语义空间来计算相似度,在训练生成器的时候就可以通过计算img-text similarity得到一个fine-grained loss ...
Prior work either simply aggregates the similarity of all possible pairs of regions and words without attending differentially to more and less important words or regions, or uses a multi-step attentional process to capture limited number of semantic alignments which is less interpretable. In this ...
作业查重软件,它实现了程序代码、文档文本、图片之间的相似度检查。a code-similarity, text-similarity and image-similarity computation software for the codes, documents and images of assignment. - xufuzhou1201/antiplag
A method and system are disclosed for conducting text-based searches of images using a visual signature associated with each image. A measure of string similarity between a query and an annotation associated with each entry in a first database is computed, and based upon the computed string simi...
