Roll training of head posture abnormal
zlyxm opened this issue · comments
1. 300w-lp-roll-krls_0.001_0.1.dat Training file size comparison ：
dataset 4000
Roll ：240MB， Pitch：14.9MB， Yaw：23.3MB
dataset 5000
Roll ：337MB， Pitch：18.4MB， Yaw：27.3MB
dataset 8000
Roll ：694MB， Pitch：28.1MB， Yaw：38,1MB
Obviously 300w-lp-roll-krls_0.001_0.1.dat is more than ten to twenty times larger than Pitch or Yaw
2. Roll testing num_wrong is too large：
Head Pose Training
testing num_right: 872
testing num_wrong: 128
testing accuracy: 0.8720
and me
testing num_right: 951
testing num_wrong: 49
testing accuracy: 0.9510
train accuracy: 0.9998, test accuracy: 0.9510
But Pitch and Yaw testing accuracy are both greater than 0.96
3. The actual test roll error is too large
Pitch and Yaw are very easy to use, but Roll is wrong
I don't know where the problem is, can you help me?
@zlyxm
Roll is very hard to detect exactly.
So machine learning Krls could haave a hard time.
This issue happens for me too.
yes,Maybe the data set is insufficient. Maybe too many key points cause interference. Generally speaking, when we recognize the roll of a face, we only need to judge whether the eyes are parallel, and whether the center point of the eyes and the chin form an inverted triangle, etc.
I need these data set all .dat files. could you help me ?
find you the files? i can´t find it
Pls where can i find those files : 300w-lp-roll-krls_0.001_0.1.dat & 300w-lp-pitch-krls_0.001_0.1.dat & 300w-lp-yaw-krls_0.001_0.1.dat , cuz i didn't find them when i downloaded the zip file here.
