| ~~1~~ | ~~Line Correction~~ | ~~linecorrect.c, linematch.c~~ | ~~Row-by-row median/polynomial alignment. Essential for raw SPM data with scan-line artifacts.~~ **DONE** |
| ~~2~~ | ~~Scar Removal~~ | ~~scars.c~~ | ~~Detect and interpolate scan-line defects (horizontal streaks).~~ **DONE** |
| 3 | Facet Leveling | facet-level.c | Orient the dominant surface facet to horizontal. Better than plane level for terraced/stepped surfaces. |

| ~~4~~ | ~~Morphological Mask Ops~~ | ~~mask_morph.c~~ | ~~Erode, dilate, open, close on grain masks. Needed to clean up thresholded masks.~~ **DONE** |
| ~~5~~ | ~~1D FFT Filter~~ | ~~fft_filter_1d.c~~ | ~~Bandpass/lowpass/highpass filtering of LINE profiles.~~ **DONE** |
| ~~6~~ | ~~2D FFT Filter~~ | ~~fft_filter_2d.c~~ | ~~Frequency-domain filtering of DATA_FIELDs (remove periodic noise, etc.).~~ **DONE** |
| ~~7~~ | ~~Autocorrelation (ACF)~~ | ~~acf2d.c~~ | ~~2D autocorrelation function. Reveals periodic structures and correlation lengths.~~ **DONE** |
| ~~8~~ | ~~PSDF~~ | ~~psdf2d.c~~ | ~~Radial/2D power spectral density function. Complementary to ACF for roughness characterization.~~ **DONE** |
| 9 | Fractal Dimension | fractal.c | Multiple methods: partitioning, cube counting, triangulation, PSDF, HHCF. Quantifies surface complexity. |
| 10 | Curvature | curvature.c | Local mean/Gaussian curvature maps. Useful for feature identification. |
| 11 | Grain Distance Transform | mask_edt.c | Euclidean distance from grain boundaries. Useful for spatial distribution analysis. |
| 12 | Watershed Segmentation | grain_wshed.c | Automatic grain detection without manual threshold. More robust than simple thresholding. |
| 13 | Rotate / Flip | rotate.c, basicops.c | Basic geometric transforms (90°, arbitrary angle, mirror). |
