About MAE, MSE calculation

[dongzelian]

Hello, thank you for releasing the pytorch code. I want to ask a question about the calculation of MAE and MSE. When calculating the MAE and MSE, the ground-truth is the integration of target density map. However, the integration of target density map is lower than the number of ground-truth crowd due to the loss of the edge when generating the target density map. How to solve the problem?
