Practical usage requires the operation to be fast, energy efficient and easy to implement. In this paper, we present a design of the Minimum Distance Classifier based on an FPGA platform. It is optimized by the pipelined structure to strike a balance between device utilization and computational speed. In addition, the dimension of the feature space is modeled as a generic parameter, making it possible for the design to re-generate hardware t","authors_text":"Ashkan Hashemi, Benny Th\\\"ornberg, Jingbo Zhao, Yan Shi","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.IV","submitted_at":"2022-12-12T08:51:43Z","title":"Color Segmentation on FPGA Using Minimum Distance Classifier for Automatic Road Sign Detection"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2212.08657","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:0f2d93a06e7772a336a53ed4f01613e2016eb8ca71d16cf1320f60e94e31d5ec","target":"record","created_at":"2026-07-05T05:26:13Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"b6361da2b96b0764dbcb460728af54699d5396e32d8ed0642cacdd94d907284e","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.IV","submitted_at":"2022-12-12T08:51:43Z","title_canon_sha256":"bcadd10116a3fc01619b9dc5203379cf10e4958d60c867d2213e6a4e082f71f3"},"schema_version":"1.0","source":{"id":"2212.08657","kind":"arxiv","version":1}},"canonical_sha256":"dee46dfc2178951d3f51e1409174f24bbba13298cf9ad5e1928071a462f78168","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"dee46dfc2178951d3f51e1409174f24bbba13298cf9ad5e1928071a462f78168","first_computed_at":"2026-07-05T05:26:13.023691Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:26:13.023691Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"XklLcZG3BTN8tvcgrUURx2v9Qz8xrB1NVnclBhZ/k4furEXRPbH5QpVwzy+UP17m3GqMOJtOL2wVoIVnnOL1Bw==","signature_status":"signed_v1","signed_at":"2026-07-05T05:26:13.024131Z","signed_message":"canonical_sha256_bytes"},"source_id":"2212.08657","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0f2d93a06e7772a336a53ed4f01613e2016eb8ca71d16cf1320f60e94e31d5ec","sha256:0584289a5488af323e39b344a7cdfb43dc959b658bec42fed67e54b42a392b45"],"state_sha256":"bc3119a2c57e6e5572b5f1c0ae3d34fcb1dccbeaafd3d34b875c000594a8a834"}
