Image Retrieval of Tourism Landscape in Rural Revitalization Based on Wireless Communication Network

Table 3

The return rate and accuracy of experimental results for different numbers of received search information.

Return the number of search results (frequency)	Precision rate (%)	Recovery rate (%)
3	0.30	0.20
5	0.40	0.40
8	0.375	0.60
10	0.40	0.80

From the table, we can get that with more and more search information received, the accuracy of recognizing images will become smaller and smaller, and the return rate will also increase.
