Embodiment Construction
[0083] The present invention will be further described below in conjunction with examples and drawings, but the embodiments of the present invention are not limited to this.
[0084] Such as figure 1 with figure 2 The shown method of hash image retrieval based on deep learning and low-rank matrix optimization includes the following steps:
[0085] S1. Obtain data, label and preprocess the data, and construct a database for image retrieval, including the following steps:
[0086] S11. Determine the scenes or objects that the data set focuses on, such as indoor scenes including TV, air conditioners, people, etc.; collect image data related to human indoor life scenes through web crawlers, and manually filter the image data to remove excluding human indoors Pictures of life scenes to get the data set Where x i Represents the i-th picture in the data set, N=50,000 is the total number of images in the data set;
[0087] S12. Perform category labeling on the images of the data set. The ...
