Recent trackers choosing AlexNet as their backbone to extract features have gained great success. However, AlexNet is too shallow to form a strong feature representation, the tracker based on the Siamese network have an accuracy gap compared with state-of-the-art algorithms. To solve this problem, this paper proposes a tracker called SiamPF. Firstly, the modified pre-trained VGG16 network is fine-tuned as the backbone. Secondly, an AlexNet-like branch is added after the third convolutional layer an","authors_text":"Dong Yin, Rui Zhang, Zhipeng Zhou","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2019-07-18T05:26:08Z","title":"A Strong Feature Representation for Siamese Network Tracker"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1907.07880","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":"sha256:96238e61979bea368b3ec2e87be4bd2c925a42b6de3dadfc87ebfcf242d78b69","target":"record","created_at":"2026-05-17T23:40:15Z","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":"59f9f69e7e748a19bcc0d7176f15e92deb7200315fe254a9bb859e60ec8335af","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2019-07-18T05:26:08Z","title_canon_sha256":"74ba38f7befeca46898ff95ea5d4def440ea65d1a63801c1537c26ceaedf6016"},"schema_version":"1.0","source":{"id":"1907.07880","kind":"arxiv","version":1}},"canonical_sha256":"4cde0b7490f52c0af1d672cb611783cbdaa3cb86849dd20480191725b20cf961","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4cde0b7490f52c0af1d672cb611783cbdaa3cb86849dd20480191725b20cf961","first_computed_at":"2026-05-17T23:40:15.838787Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:40:15.838787Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"bYpDia63Ae4bJ93cPBBzUnauaZNVwULLDRRNQaV7KdlJhpT7+PngUcI1Qxh6E3MbJ13YES0lEpoRTN6bE6ZADQ==","signature_status":"signed_v1","signed_at":"2026-05-17T23:40:15.839542Z","signed_message":"canonical_sha256_bytes"},"source_id":"1907.07880","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:96238e61979bea368b3ec2e87be4bd2c925a42b6de3dadfc87ebfcf242d78b69","sha256:e9321a8b0db05501750febc1f9b0cd71e3dad93b1b6af56657ce926ef038dc0c"],"state_sha256":"f7da41c2681aa9939089b1faeeccf40b82f0cd3f15398fb145e72373f96beee0"}
