about

nx_image.nx -- pure-math image primitives. No model files, no learned weights, no VLM. Classical computer vision math: pixel access, grayscale conversion, 3x3 convolution, Sobel gradient, gradient magnitude via integer sqrt, histogram. All i64. Uses nx_i128 muldiv where intermediate products risk overflow (per NUMERIC_TIER_LADDER + S_CLASS_MATH_DOCTRINE). genealogy_id: gonzalez_woods_digital_image_processing + canny_1986 + sobel_feldman_1968 lineage_id: convolution + gradient + integer_pixel_arithmetic axioms: NX_AX_ALG_DISTRIBUTIVITY, NX_AX_ALG_COMMUTATIVITY nx_safety_envelope: intended_use: "Image container + convolution/gradient/ integer-pixel ops. Foundation for all substrate visual processing." sil_target: SIL2 (visual integrity in safety-relevant UI -- e.g. medical imaging, aviation HUDs) asil_target: QM dal_target: DAL C evidence: [Image_canonical_container_type, bounded_pixel_loops, axiom_distributivity_commutativity_tagged] hazard_register: [bug-tape-image-stride-not-validated, bug-tape-OOB-pixel-read-via-bad-coord, bug-tape-channel-count-mismatch-corruption] residual_risk: "Image stride + dimensions are caller- supplied. Substrate validates bounds at function entry; loop bodies trust them. Image format compatibility (RGB vs RGBA vs YUV) is upstream responsibility." verdict: NOT_YET_EVALUATED
