A video colorization method based on semantic correspondence and alignment is proposed, constructing a video colorization model SCAColor. This model includes a semantic correspondence pre-colorization subnet, a bidirectional optical flow-guided semantic alignment subnet, and a color refinement subnet. The semantic correspondence pre-colorization subnet learns the semantic association between grayscale frames and reference frames to generate preliminary colorization results and a semantic similarity map.
