IVCA: Inter-Relation-Aware Video Complexity Analyzer
<|reference_start|>IVCA: Inter-Relation-Aware Video Complexity Analyzer: To meet the real-time analysis requirements of video streaming applications, we propose an inter-relation-aware video complexity analyzer (IVCA) as an extension to VCA. The IVCA addresses the limitation of VCA by considering inter-frame relations, namely motion and reference structure. First, we enhance the accuracy of temporal features by introducing feature-domain motion estimation into the IVCA. Next, drawing inspiration from the hierarchical reference structure in codecs, we design layer-aware weights to adjust the majorities of frame complexity in different layers. Additionally, we expand the scope of temporal features by considering frames that be referred to, rather than relying solely on the previous frame. Experimental results show the significant improvement in complexity estimation accuracy achieved by IVCA, with minimal time complexity increase.<|reference_end|>
