- Abstract:
-
Due to the limited computing resources, the embedded platform can not run the deep learning model with huge amounts of calculation and parameters in real time. An improved lightweight face recognition algorithm L-mobilenet v2 is proposed based on the mobilenet v2. The algorithm first optimizes the original network structure, then uses the triplet loss function as the main loss function to change the softmax loss in traditional classification task to Am-softmax, which is used as the auxiliary loss function, and uses 490 thousand images of 10575 people for joint training. Compared with the previous model and training method, the recognition accuracy of the new model on LFW test data set and self-made data set has reached 98.56% and 95%, respectively, which increased the recognition accuracy by 1.56 % and 7.1% while reducing the number of model parameters by 72.3%. And at the same time, the rate of frame recognition on average on the embedded platform Jetson nano has increased by 36.3%. The model can run in real time on mobile terminals with limited computing resources.
