C23 Dimensionality Reduction Codec

🔬 PCA Image Compression Test Lab

Test RCRE's zero-dependency Principal Component Analysis (RPCA) spatial block codec. Compress photos into orthogonal low-dimensional subspace bases with 8-bit uniform quantization, inspect learned eigen-basis patches, evaluate rate-distortion curves (PSNR vs. Bitrate), and export bitstreams matching the C23 CLI engine (rcre-pca).
