Module texture_simd 

SIMD-accelerated texture analysis using Gray-Level Co-occurrence Matrix (GLCM)

This module provides high-performance implementations of GLCM computation and Haralick feature extraction using SIMD instructions.

Performance

Expected speedup over scalar implementations:

• GLCM construction: 2-3x (SIMD histogram updates)
• Haralick features: 2-4x (SIMD arithmetic and reductions)
• Texture feature images: 2-3x (parallel window processing)

Supported Operations

• glcm_construct_simd: SIMD-optimized GLCM matrix construction
• glcm_normalize_simd: Fast SIMD normalization
• haralick_features_simd: SIMD-accelerated feature computation
• texture_contrast_simd: Fast contrast feature extraction
• texture_energy_simd: Energy/ASM computation with SIMD

Example

use oxigdal_algorithms::simd::texture_simd::glcm_construct_simd;

let quantized = vec![0_u8; 1000];
let mut glcm = vec![0.0_f32; 256 * 256];

glcm_construct_simd(&quantized, &mut glcm, 100, 10, 256, 1, 0)?;
