[0047]In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further elaborated below in conjunction with the accompanying drawings.
[0048] In this example, see figure 1 As shown, the present invention proposes a crowd gathering sensitive image detection method, including steps:
[0049] S100, collecting image data in the crowd, and obtaining image data sets of the original domain and the target domain respectively;
[0050] S200, establish a supervised discriminant sparse transfer model, establish a transfer model capable of simultaneously learning the common subspace and sparse expression reconstruction matrix of the original domain and the target domain, and add a supervised discriminant regular term to the transfer model; the transfer model can use an LSDT model, The LSDT model is a completely unsupervised model;
[0051] S300, using the image sample label information to obtain the common subspace...
