The application provides a fine-grained face age estimation method based on horizontal pyramid matching, and relates to the technical field of image classification. The method is used for face images in different backgrounds. Firstly, the position of the face in the image is detected by using a face detection algorithm. Then, the face image is input into a residual network model Resnet50 to obtain an age feature map. The age feature map is horizontally divided into different pyramid scales to obtain multiple feature slices. Finally, global average pooling and global maximum pooling are respectively performed on each feature slice to obtain the overall age feature and the local age feature of the face, and the face age estimation is completed. The method solves the combination problem of the global feature and the local fine-grained feature of the face age, and realizes the extraction of the overall age feature and the local most recognizable fine-grained feature of the face.

The invention relates to a reinforced flame-retardant cellulose aerogel material and a preparation method thereof.The preparation method comprises the following steps that S1, polycarboxylic acid, a catalyst and water serve as raw materials to prepare a polycarboxylic acid solution, halloysite is put into the polycarboxylic acid solution to be stirred, and then polycarboxylic acid modified halloysite is obtained through roasting and aftertreatment; s2, adding the polycarboxylic acid modified halloysite into the cellulose solution to obtain a mixed solution, and performing aging replacement treatment on the mixed solution to obtain wet gel; and drying the wet gel to obtain the reinforced flame-retardant cellulose aerogel material. The halloysite is used as a raw material for enhancing flame retardance of the cellulose aerogel, polycarboxylic acid is used as a cross-linking agent to enhance the binding force between inorganic halloysite and organic cellulose, and meanwhile, the cellulose is wound and cross-linked by taking the modified halloysite as a framework, so that the mechanical property and the flame-retardant effect of the material are effectively improved.
