nx_texture.nx

nx_texture.nx -- texture primitives (V5 of vision rollout). Two complementary descriptors: 1. GLCM Haralick features (Haralick 1973) Gray-Level Co-occurrence Matrix counts pixel-pair frequencies at offset (dx, dy). Derived statistics: contrast, energy, homogeneity. 2. Local Binary Patterns (Ojala 1996, 2002) 8-bit signature comparing each pixel to its 8 neighbors. Robust to monotonic illumination change. Histogram of LBP codes characterizes texture. What this unlocks: + material discrimination (skin / fabric / fur / feather / concrete) + grass vs concrete vs sand for outdoor scene classification + texture-based salience (busy region vs flat) + texture homogeneity check for image-quality (over-blurred?) All i64. GLCM features in Q10 (scaled by 1024) for cross-image comparison. genealogy_id: haralick_1973_glcm + ojala_1996_lbp + ojala_2002_uniform lineage_id: co_occurrence_matrix + binary_pattern_histogram
