(Image Retrieval):语言监督可以用来指导模型根据文本查询来检索与之相关的图像。例如,给定一个文本描述,模型需要找到与之最匹配的图像 视觉领域的自监督学习—理解,Self-supervised learning: 在视觉领域,自监督学习利用图像数据自身的信息进行学习,而无需人工标注的标签。这种方法通过设计自动生成标签或目标,使模型在学习...
Contrastive Language and Image Pairing (CLIP), a transformative method in multimedia retrieval, typically trains two neural networks concurrently to generate joint embeddings for text and image pairs. However, when applied directly, these models often struggle to differentiate between visually distinct ...
Image retrieval is a computer vision task of browsing, searching, filtering and querying from large datasets of images. Nowadays Neural Networks are used for this task, especially in the cases where the images are unlabeled. The most popular example is Google Image Search. A user just provid...
使用一个reference set(image text pair),用pretrained模型(DINO-S/sentence-bert) 抽取image/text特征作为外部embed knowledge。训练时使用ANN搜索得到的topk的image embedding 和关联的textembedding,使用multi head cross attention之后的特征增强目标模型的vision embedding,作为clip训练的vision侧特征,得到在下游任务上更...
视频检索,CLIP4clip中CLIP指OpenAI的CLIP模型,clip指的是视频中的clip。CLIP模型很适合做Retrieval(检索)任务,因为它就是做图像和文本之间相似性,根据相似性可以去做ranking、matching以及retrieve等任务。而且由于双塔结构(图像文本编码器分开),得到的image embedding和text embedding做一步点乘就可以计算相似度,因此非常容...

2.1CLIP4Clip(an empirical study of CLIP for end to end video clip retrieval) 如果使用最简单的方法,直接把每一帧都单独地打成image patch,再把patch输入vit,然后去得到最后的cls token的话,得到的就不再是一个cls token,而是一系列的cls token,比如输入10帧,最后就会有10个cls token,也就是10张图片的整...
