Description

请问大家有用这个做图片搜索的吗?
我按教程,在pytorch下用ResNet18模型,抽取图片的特征向量入库。然后检索。除非使用一张图片,可以检索出来。稍微做些修改的,都不行。是特征向量提取的问题,还是距离计算的问题?

Research direction

The issue mentions a tutorial using PyTorch and ResNet18 to extract image feature vectors, followed by vector retrieval. Start by reviewing that extraction and the distance-calculation steps; done would require identifying why lightly modified images fail to retrieve and documenting a reproducible diagnosis.
