IntelligentDetailStabilizer (IDS)

Gentle, fast post‑pass for stabilizing micro‑detail and suppressing noise while preserving sharpness.

Overview

• Two‑stage blur/sharpen split with strength‑controlled recombination.
• Uses SciPy Gaussian if available; otherwise a portable PyTorch separable blur.
• Operates on images (BHWC, 0..1) and returns a single stabilized IMAGE.

Inputs

• image (IMAGE)
• ids_strength (float, default 0.5, range −1.0..1.0)

Outputs

• IMAGE — stabilized image

Tips

• Start around ids_strength≈0.5 for gentle cleanup.
• Negative values bias toward more smoothing; positive increases sharpening of denoised base.
