Implementing Perceptual Hash for Image Similarity Matching in Mini Programs

To automate matching of theme‑image URLs in a mini‑program skin‑changing feature, the author adopts perceptual hashing—using algorithms such as aHash, pHash and dHash—to generate compact 64‑bit fingerprints, compare them via Hamming distance, and reliably identify visually similar images despite minor edits or scaling.
