近日,抽空跑通了delf模型,它已经成为tensorflow models中research的一个子工程(见网址:https://github.com/tensorflow/models/tree/master/research/delf)。
该项目的介绍如下所示:
This project presents code for extracting DELF features, which were introduced with the paper"Large-Scale Image Retrieval with Attentive Deep Local Features". A simple application is also illustrated, where two images containing the same landmark can be matched to each other, to obtain local image correspondences.
DELF is particularly useful for large-scale instance-level image recognition. It detects and describes semantic local features which can be geometrically verified between images showing the same object instance. The pre-trained model released here has been optimized for landmark recognition, so expect it to work well in this area. We also provide tensorflow code for building the DELF model, which could then be used to train models for other types of objects.
