Cricket bat-gated pose-library — 17 / 18 / 19 关节并行对比

Stage 0 bat-event gate → Stage 1 subjectness 选人 → Stage 2 库匹配。 gate 与选人三变体共享，只替换 Stage-2 库：17 纯人体 · 18 +bat中心(best.pt 检测器) · 19 +handle/tip 角度(训练的 bat-kp 模型)。 测试集 = Video Set 1 (7 非板球, gate 应拒) + batting (3 板球)。 匹配库暂时只含 batting 模板(47 个 exemplar，已去掉 bowling/fielding)，所以结果只会是击球姿态。 每段视频画实时分数曲线(gate_prob + sim17/18/19 over time)，下面三列分别是各变体 Top-3 peak(渲染帧→最近模板)。 帧上绿色粗框 = 匹配中的那个人(pose)，叠加身体骨架 + ●bat中心 + ●握把→●棒尖；其他人灰细框。
