人体骨骼14点调参心得

原始工程来源于https://github.com/edvardHua/PoseEstimationForMobile

但是其中有些BUG,我略作修改,如果你没法跑起来原工程,可以把我的training文件夹弄过去覆盖掉原工程的。

150M计算量调参心得(双核A53约50ms)

(1)stage_num=3,分辨率192x192调参阶段

stage_num=3时,网络设计捉襟见肘,channel和kernel都不大。

这一阶段包括zq1_cpm, zq7_cpm, zq8_cpm, zq9_cpm, zq10_cpm。

PCKh0.2从62.4提高到64.81, 模型结构请查阅代码, 精度请查阅xls。

(2)stage_num=2,分辨率192x192调参阶段

stage_num=2时,网络设计可以活动的地方较大,随便设计一个里面超过先前stage_num=3

这一阶段baseline是zq11_cpm, PCKh0.2达到65.98, 越改越差的包括zq12_cpm, zq13_cpm, zq14_cpm, zq15_cpm。

调参过程包括zq22_cpm,(未完待续)

模型结构请查阅代码,精度请查阅xls

(3)stage_num=2,分辨率224x224调参阶段

考虑到heatmap分辨率太小会导致无论无何都不可能太准,尝试加大分辨率。但不得不缩减channel和kernel。

这一阶段baseline是zq16_cpm (模型设计思路来源于zq11_cpm), PCKh0.2达到65.64, 越改越差的包括zq17_cpm, zq18_cpm, zq19_cpm, zq20_cpm

第一次改好的结构是zq21_cpm, PCKh0.2达到66.73
