In computer graphics and 3D rendering, color bleeding is the phenomenon in which objects or surfaces are colored by reflection of colored light from nearby surfaces. This is a visible effect that appears when a scene is rendered with Radiosity or full global illumination, or can otherwise be simulated by adding colored lights to a 3D scene.

A video colorization method based on semantic correspondence and alignment
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. The bidirectional optical flow-guided semantic alignment subnet incorporates the colorization result of the previous frame and the true color value of the current frame, correcting feature biases while enhancing temporal consistency. The color refinement subnet further optimizes local colors and outputs the final colorization result. Extensive experimental results on public benchmark datasets demonstrate that the video colorization method based on the video colorization model can achieve reasonable colorization of videos with natural and rich colors and smooth inter-frame transitions, effectively avoiding color bleeding and exhibiting good network robustness.
