物体検出のトレンド(3/4)

• トレンド集計からの気付き

– 例年と比較して物体検出の採択数は増加

– 平面の物体検出と3次元物体検出が半分以上を占める

– 例年と比較して3D物体検出に関する研究が急増⤴⤴⤴

• 自動運転に導入するための技術として研究されているものが多
い印象?

– 採択数増加にもかかわらず,Text detectionやnovelty detectionは
減少

• 何かに特化した物体検出は減少傾向?

5
物体検出のトレンド(4/4)

• Pointベースの物体検出手法が増加

– CenterNetの登場以来,高精度・高速として注目

– 今年のCVPRでもいくつか論文が採択されている









– もちろんアンカーベースも提案されている

SaccadeNet
 CentripetalNet

Multiple Anchor Learning
