• `resize_b_to_a` → resizes B to match A
• `center_crop_to_min` → crops both to the smaller overlap
• `pad_to_max` → pads smaller one with black pixels | +| **color_map** | combo | `jet` | The color scheme for heatmaps:
• `jet` → rainbow style (bright = more difference)
• `grayscale` → black–white map | +| **invert_ssim** | bool | `true` | Flip SSIM visualization so differences appear **bright** instead of dark. | +| **ms_scales** | int | `3` | Number of scales for **MS-SSIM**. Higher = more robust but slower. | +| **resid_gain** | float | `2.0` | Strength multiplier for the **Residual Visualization**. Higher = amplifies added/removed details more strongly. | +| **fft_log_eps** | float | `1e-3` | Stabilization constant for FFT log spectrum. Adjust only if you see black/overblown spectra. | +| **enable_lpips** | bool | `false` | Whether to compute the **LPIPS perceptual heatmap** (uses VGG16 features, slower, more VRAM). | +| **denoise_sigma** | float | `1.0` | Standard deviation for Gaussian blur in **Denoiser Residual**. Controls how aggressively “noise” is extracted. | +| **denoise_gain** | float | `2.0` | Amplification factor for the residual visualization in **Denoiser Residual**. | +| **roundtrip_scale** | float | `0.5` | Downscale factor for **Round-Trip Stability** test. (0.5 = downscale by 2×, then upscale again). | +| **roundtrip_kernel** | combo | `bicubic` | Resampling kernel for round-trip test. Options: `bicubic`, `bilinear`, `lanczos`. | + +--- + +👉 **Tip:** +- Start with defaults. +- Enable `LPIPS` only if you want human-perception-like feedback. +- Use `invert_ssim = true` for easier visual spotting (bright = problem). +- Play with `resid_gain` and `denoise_gain` if maps look too weak/too strong. + +
