Embodiment Construction
[0030] The present invention will be further described below in conjunction with accompanying drawing:
[0031] The technical scheme of this embodiment is as figure 1 Shown:
[0032] First, the retrieval system extracts the underlying physical features of all the images in the image library offline in advance. The extracted features include: color features, texture features, shape features, spatial distribution features and local invariance features, and generate image feature library V; then Such as figure 2 The online retrieval process shown, the specific flow of the online retrieval process is as follows:
[0033] (1) The user submits query information, which can be the query image Q N , it can also be the input text information, or the query image and text information exist at the same time; the retrieval system for the query image QN Perform feature extraction, and extract keywords from the input text information; the system performs feature similarity matching S1 on ...
