1. A webserver-based video content production method for printing a holographic stereogram photo, the webserver-based video content production method comprising:
providing image data acquired by imaging a subject through a user terminal to a web;
providing the received image data to a webserver;
performing a second-half task on the received image data using deep learning to produce video content; and
providing the produced video content to the user terminal through the web; and
wherein the production of the video content comprises:
recognizing a face in all frames of the image data received from the web;
deleting one or more frames with closed eyes among frames of the image data in which the face is recognized;
only extracting frames having a certain variation less than a threshold from the frames of the image data, in which the one or more frames with closed eyes has been deleted, to stabilize images and equalize the frames of the image data;
separating the subject and a background in the extracted frames having the certain variation less than the threshold; and
performing postprocessing on the images in which the subject and the background have been separated to produce video content; and
wherein the deleting of the one or more frames with closed eyes comprises:
connecting landmarks of a region, which corresponds to an eye among facial landmarks representing major features of the face, with lines and then generating the region corresponding to the eye;
calculating an area of the generated region corresponding to the eye; and
when the calculated area is a set threshold or less, recognizing one or more corresponding frames as frames with closed eyes and deleting the one or more corresponding frames.
