Embodiment 1
[0109] 1. Raw input data such as image 3 , as shown in 4 and 5, the 3 models are a, b, and c respectively, and each model has 3 pictures
[0110] 2. The image description module groups the images of the same shooting scene into one group, a total of 3 groups, such as image 3 , 4, 5 as shown:
[0111] 1) Take the image of model a and extract features to build a retrieval set. The method for extracting image features can use a convolutional neural network model or a traditional feature extraction method, such as HOG features and SIFT features.
[0112] 2) For the images (query images) of models b and c, extract features according to the method in step 1), and perform distance measurement with the retrieval set. The distance measurement method can adopt Euclidean distance, Manhattan distance, and distance measurement methods such as cosine of included angle.
[0113] 3) Group the query image and the retrieval set images closest to it into one group.
[0114] 3. The image d...
