1. A video analysis method comprising:
a first image analysis step of analyzing an input image frame on an edge side;
a difference value estimation step of estimating a difference value between an evaluation value of an analysis result of the first image analysis step and an evaluation value of an analysis result being predicted when the input image frame is analyzed by a cloud server; and
a filtering step of determining whether to transmit the input image frame to the cloud server, based on the difference value.
