Remove the target object, its shadow, reflection, and other visual effects in a single denoising step while keeping unaffected regions intact.

Why TurboClear

Edit what matters. Preserve what does not.

Object removal must reconstruct areas influenced by the target while leaving unrelated content unchanged. Generic one-step objectives do not explicitly model this spatial asymmetry, which can leave residual effects or introduce unnecessary background changes.

TurboClear couples Region-Calibrated Distribution Matching with Learnable Spatial Fusion. The resulting SDXL-based student preserves the teacher's asymmetric edit-and-preserve behavior while reducing iterative diffusion inference to one step.

Qualitative results

Objects disappear. Structure stays.

Five OBER-Wild examples from the updated qualitative comparison in the paper.

Method

Region-aware distillation, spatially learned fusion

TurboClear training and inference pipeline with RDM and LSF
RDM calibrates distribution matching across affected and preserved regions during training. At inference, LSF predicts latent- and pixel-space gates to combine the generated output with the input stream.

Efficiency

Quality without the iterative cost

TurboClear reaches the strongest PSNR in the comparison while using substantially fewer denoising FLOPs than multi-step diffusion removal systems. Bubble area denotes model parameter count.
