This invention discloses an image-aware hashing method and system based on residual networks, belonging to the field of information security; it includes S1, using a residual network to perform a first-stage training on an image group to obtain a hash sequence; S2, reading the weights after the completion of the first-stage training, using these weights to perform a second-stage training, and applying a loss function L... f2 By adjusting the network to increase the distance between the original image and the approximate image, the network is ultimately able to distinguish between the original image and the approximate image, thus overcoming the shortcomings of existing technologies.

This invention relates to the field of biomedical technology and proposes RBP4 and Ferritin as biomarkers for evaluating the efficacy of hormone therapy for allergic rhinitis. The biomarkers include one or a combination of RBP4 and Ferritin. Studies have confirmed that both RBP4 and Ferritin are capable of distinguishing between hormone-sensitive and hormone-insensitive allergic rhinitis. RBP4 is expressed at higher levels in the hormone-sensitive allergic rhinitis group, while Ferritin is expressed at higher levels in the hormone-insensitive allergic rhinitis group. Compared to single biomarker detection, the combined use of RBP4 and Ferritin significantly improves the differential diagnostic efficacy, providing better differentiation between the two patient groups.

The invention provides a brocade pattern generation method and system based on a diffusion model, and relates to the technical field of pattern generation, and the method comprises the steps: collecting a brocade sample image, extracting the structural features of a brocade sample pattern, and building a multi-mode joint embedding space; analyzing a design intention input by a user into a multi-modal condition vector, and mapping the multi-modal condition vector to a multi-modal joint embedding space to obtain condition embedding features; introducing a structure perception attention mechanism into the noise prediction network of the diffusion model, generating a structure constraint feature map, and in the reverse denoising process of the diffusion model, carrying out hierarchical fusion on the condition embedding features and the structure constraint feature map to obtain a brocade generation result; and performing brocade process feasibility verification on the brocade generation result, and outputting a brocade pattern. According to the method, the intelligent level and the production efficiency of brocade pattern generation can be improved by combining a structure perception attention mechanism and a hierarchical fusion strategy.

This application discloses a method for identifying and classifying furniture surface defects based on image detection. The method includes: acquiring an original image of the furniture surface; converting the original image into luminance and chrominance components to obtain a standard luminance map; generating a candidate region set based on the standard luminance map and chrominance components; calculating the structure tensor based on the standard luminance map using overlapping local windows to determine the local principal direction and directional validity, and constructing a pixel-level principal direction field and directional validity map; further performing directional-guided background reconstruction on the standard luminance map based on the principal direction field and directional validity map to obtain a background reconstruction map and generate a residual response map; finally, extracting texture interpretation features and defect interpretation features for each candidate region, inputting them into a competition suppression model for discrimination, determining the defect category of the retained regions, and outputting the defect location and defect category. This invention is applicable to the identification and classification of furniture surface defects with directional textures.
