[0003] However, the existing age-labeled image set is a color image set, and the convolutional neural network model trained based on this image set can only predict the age of faces in color images
For infrared images, due to the lack of age-labeled data sets, it is impossible to train a convolutional neural network model for age prediction of faces in infrared images

The embodiment of the invention discloses an age prediction method and device for an infrared image. The method comprises the following steps: acquiring a to-be-processed infrared image; detecting a first face area in the to-be-processed infrared image, and constructing a to-be-processed target image containing the first face area; inputting the to-be-processed target image into the infrared convolutional neural network model to obtain first predicted age distribution of a person corresponding to the first face area; wherein the infrared convolutional neural network model is a difference valuebetween age distribution corresponding to each infrared sample image output by the initial infrared convolutional neural network model and Gaussian distribution generated by a corresponding age labeling result after each infrared sample image is input into the initial infrared convolutional neural network model; and adjusting each parameter in the initial infrared convolutional neural network model according to the expected value of the age distribution corresponding to each infrared sample image and the difference between the expected value of the age distribution corresponding to each infrared sample image and the corresponding age labeling result. By applying the scheme provided by the embodiment of the invention, age prediction can be carried out on the infrared image.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to an age prediction method and device for infrared images. Background technique [0002] At present, age prediction based on surveillance images mainly uses convolutional neural network methods. Specifically, firstly, the convolutional neural network model needs to be trained through sample images and accurate age labeling results, and then the age prediction of the face in the image to be predicted can be performed based on the trained convolutional neural network model. [0003] However, the existing age-marked image set is a color image set, and the convolutional neural network model trained based on the image set can only predict the age of the faces in the color image. For infrared images, due to the lack of age-labeled data sets, it is impossible to train a convolutional neural network model for age prediction of faces in infrared images. Therefore, in orde...
