benches	chore: Disable cargo check in local dev (#6439) ## Changes Made I believe the cargo check pre-commit commands are useless in local development. They should run with cargo clippy anyways (since check just ensures that the crate compiles without errors and maybe warnings). Plus, because we do it 2 times with different flags, it causes a lot of recompilation which just makes it slow. So i disabled them for git commits. They are still enabled when you do make precommit and in CI to be safe.	7 个月前
src	feat: support various image hash functions (aHash, dHash, pHash, wHash, crop-resistant hash) for deduplication (#6338) Implements 5 image hashing algorithms for image deduplication: aHash (Average Hash): Compares each pixel to the mean intensity dHash (Difference Hash): Compares adjacent pixel differences pHash (Perceptual Hash): DCT-based frequency domain hashing wHash (Wavelet Hash): Haar wavelet transform-based hashing Crop-resistant Hash: Robust against cropping transformations ## Changes Made Added hash methods to CowImage with helper functions (dct2d_32x32, haar_2d) Added ImageHashOps trait and implementations for ImageArray / FixedShapeImageArray Added series-level functions and ScalarUDF registrations Exposed Python APIs: image_ahash, image_dhash, image_phash, image_whash, image_crop_resistant_hash Added corresponding methods to SeriesImageNamespace Added tests covering all 5 algorithms Fixed-size hashes return FixedSizeBinary(8), crop-resistant hash returns variable-length Binary. ## Related Issues Closes #4889	6 个月前
