How to use it to detect pupils in pictures
Hello, I have used your code to detect the pupil direction in the picture, and then I can only detect the left and right sides, but not the top and bottom.The pointer of the left eye is slightly off . May I ask you to modify yours values of number of self.horizontal_ratio()?
Hello!
I can only detect the left and right sides, but not the top and bottom.
The detection of top/bottom is more complicated because the distance between the top and the bottom is shorter than the distance between the right and the left.
I didn't code is_top() and is_botton() but I provided a vertical_ratio() function to get the vertical position with a ratio. The extreme top is 0.0, the center is 0.5 and the extreme bottom is 1.0. However, I think the accuracy of this ratio is quite low, it depends of your usages.
The pointer of the left eye is slightly off. May I ask you to modify yours values of number of self.horizontal_ratio()
Please share with me the values that work for you!
dear Antoine Hello, I've been testing the eyes of several people on a computer program these days. Based on their results, the data were summarized. But I don't know if it's true or not.This applies to the people around me I want to share it with you! def is_right(self): """Returns true if the user is looking to the right""" print("HR:",self.horizontal_ratio()) if self.pupils_located: return self.horizontal_ratio() <= 0.542
def is_left(self): """Returns true if the user is looking to the left""" print("HR:", self.horizontal_ratio()) if self.pupils_located: return self.horizontal_ratio() >= 0.75 I think you can use it as a reference.Also, I come from China, maybe our Chinese eyes are different from your European eyes, so the Numbers are not the same! A silly question. You can explain that to me.
what do eye_left.pupil.x ,eye_left.pupil.y mean? I don't know which unit that cross represents...... Don't laugh at me... I would like to make a judgment of the upper and lower parts of the eyeball recently. Do you have any Suggestions? I think we can modify the value of the vertical_ratio to solve the question. I don't know if i can Look forward to your reply! XD Best,Adile.
