Multi-modal composite coding image retrieval method and system

The invention provides a multi-modal composite coding image retrieval method and system, and the method comprises the steps: obtaining to-be-retrieved information, and judging the data type of the to-be-retrieved information; selecting the coarse-grained retrieval or fine-grained retrieval according to the data type of the to-be-retrieved information, wherein the fine-grained retrieval comprises the steps that when the input to-be-retrieved information comprises image description data and text description data at the same time, the two features are fused to obtain composite features, and then data retrieval is conducted through the composite features. According to the method, coarse-grained retrieval or fine-grained retrieval can be selected according to the data type, the composite features can be obtained by fusing the two features, and then data retrieval of fine-grained retrieval is carried out through the composite features; according to the method, the database construction efficiency can be improved, the flexibility of a retrieval mode is improved, the retrieval difficulty is reduced, and a solution which is uniform in precision and generalization performance and more flexible in switching between fuzzy retrieval and accurate retrieval is provided for image retrieval.

Shoeprint image retrieval method based on segmented weighting

The invention provides a shoeprint image retrieval method based on segmented weighting. The shoeprint image retrieval method based on segmented weighting comprises the steps of 1, image preprocessing,on the basis of a trained U-Net convolutional neural network model, converting an obtained shoeprint on-site photo into an on-site binary image with shoeprint information reserved; 2, feature extraction: splitting the on-site binary image and the image in a shoe sample library into an upper sub-image and a lower sub-image, and inputting the upper sub-image and the lower sub-image into a twin network for feature extraction to obtain two mutually independent sub-features; 3, calculating a feature weight matrix: respectively calculating a pixel number proportion containing shoeprint informationin the two mutually independent sub-features so as to obtain a weight matrix of the field binary image; and 4, realizing feature fusion and similarity measurement. The technical problem of how to quickly and accurately retrieve the style corresponding to the shoeprint on-site picture in the shoe sample library is solved, the characteristics that the on-site shoeprint noise influence is large and part of information is lost are comprehensively considered, and the shoeprint retrieval accuracy is improved.
