[0024] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0025] see Figure 1-2 , the present invention provides a technical solution: a deep hash-based super-resolution image retrieval system, comprising:
[0026] S1. Perform super-resolution reconstruction processing on the query image (a) and the similar image (a+), that is, input the image into the VDSR layer, and the reconstruction process is as follows:
[0027] (1) The input original image is represented by LR, and bicubic linear interpolation is performed on the image to obtain the up-sampled image UR;
[0028] (2), input UR into a 20-layer convolutional neural network to obtain high-f...
