Webmethods include VLAD [10] and, in particular, the Fisher Vector (FV) [14] which, compared to BoVW, capture signi cantly richer statistics of the visual word occurrences. Recently, … WebApr 18, 2015 · In this work, we propose to interpret Fisher-Vector-based object detectors as part-based models. Through the use of several visualizations and experiments, we show that this is a useful insight to … WebApr 6, 2024 · The pSin-EF2-puro-Vector plasmid was used as negtive control. HNSCC cells stably overexpressed TIPE3 were constructed as we previously reported [17, 19]. Briefly, the pSin-EF2-TIPE3-HA or empty vector, as well as the lentivirus packaging plasmids psPAX2 and pMD2.G, were co-transfected into 293FT cells using the calcium phosphate method. csv for software
