The embodiment of the invention provides a face recognition method and device for a small target, and the method comprises the steps: carrying out the background filtering of an obtained small targetimage, and obtaining a first image; performing noise suppression on the first image to obtain a target image; inputting the target image into a face recognition model for face recognition, and outputting a recognition result, wherein the face recognition model is obtained through training by taking a face image and a label corresponding to the face image as a training set of a convolutional neuralnetwork. According to the embodiment of the invention, the accuracy of face recognition can be improved. 本发明实施例提供一种小目标的人脸识别方法及装置，所述方法包括：对获取到的小目标图像进行背景滤除，得到第一图像；对所述第一图像进行噪声抑制，得到目标图像；将所述目标图像输入到人脸识别模型进行人脸识别，输出识别结果；其中，所述人脸识别模型通过采用人脸图像及与所述人脸图像对应的标签作为卷积神经网络的训练集训练得到。本发明实施例能够提高人脸识别的准确率。
