Embodiment Construction
[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0033] This example is oriented to the video semantic communication requirements of online interactive conferences, and implements a video semantic communication method and system based on hierarchical knowledge expression for single-person body movements and multi-person interaction behaviors in conference scenarios.
[0034] refer to figure 1 , this example is based on the video semantic communication method of hierarchical knowledge expression, including the following steps:
[0035] Step 1, build a hierarchical knowledge base K.
[0036] 1.1) Establish a semantic-aware knowledge base K 0 , which is used to store the primary structured semantic feature G extracted from the video 0 The signal-aware network W e 0 and from the primary structured semantic features G 0 Signal Reconstruction Network for Reconstructing Video
