Claim 11:
12. The eye gaze tracking method of claim 11, wherein the down-sampling network comprises M down-sampling layers, the up-sampling network comprises M layers of up-sampling layers, M is an integer greater than 1, and the M down-sampling layers are in one-to-one correspondence with the M up-sampling layers;
an input of the first down-sampling layer is a facial image, and the i-th down-sampling layer performs a convolution operation on inputted feature with different convolution kernels, combines calculation results together and transfers the combined calculation results to the (i+1)-th down-sampling layer; an input of the i-th up-sampling layer is a combination of an output of the (i+1)-th up-sampling layer and a first result, wherein the first result is a result obtained after a convolutional calculation is performed on an output of the i-th down-sampling layer, i is greater than or equal to 1 and less than or equal to M−1; and
the M-th down-sampling layer performs a convolution operation on inputted feature, and transfers a result to the M-th up-sampling layer, and an output of the M-th up-sampling layer is the eye contour in the facial image.
