Python Library for Pupil Detector of Eye Health Diagnostic Group
Project description
EYE HEALTH DIAGNOSTIC GROUP'S PUPIL DETECTOR (ehdg_pupil_detector)
This is the python package libray pupil detector created by eye health diagnostic group.
Installtion
pip install ehdg_pupil_detector
Updating
pip install ehdg_pupil_detector -U
Class Initialization and Attributes
Class Initialization with defaults
from ehdg_pupil_detector import ehdg_pupil_detector
detector = ehdg_pupil_detector.Detector()
If you do not specify any argument, it will use default vales are as follows:
- config
Default = None
If it is None then it will use following config parameters:- min_circular_ratio = 0.9
- max_circular_ratio = 1.9
- ksize_height = 13
- ksize_width = 13
- min_binary_threshold = 20
- max_binary_threshold = 255
- reflection_fill_dilation_index = 25
- reflection_fill_square_dimension = 200
- reflection_fill_color_index
Default = 0 (black)
0 means black and 255 means white in the gray scale.
It will cover the reflection on the pupil with black before using any other filters. - gaussian_blur
Default = True
It will use gaussian blur filter. - binary_fill_hole
Default = True
It will use binary fill hole function filter.
Class Initialization with custom values
from ehdg_pupil_detector import ehdg_pupil_detector
custom_config = {
"min_circular_ratio": 0.9,
"max_circular_ratio": 1.9,
"ksize_height": 13,
"ksize_width": 13,
"min_binary_threshold": 20,
"max_binary_threshold": 255,
"reflection_fill_dilation_index": 25,
"reflection_fill_square_dimension": 200
}
detector = ehdg_pupil_detector.Detector(config=custom_config, reflection_fill_color_index=0, gaussian_blur=True,
binary_fill_hole=True)
The reflection_fill_color_index must be between 0 and 255.
It is indexing how black or white gonna cover on the reflection of the pupil.
0 index is blackest and 255 index is whitest.
If you wanna turn off reflection fill function, add
reflection_fill_color_index=False
instead of
reflection_fill_color_index=0
Class Function
get_config_info()
It is to check the current config information.
from src.ehdg_pupil_detector import ehdg_pupil_detector
custom_config = {
"min_circular_ratio": 0.9,
"max_circular_ratio": 1.9,
"ksize_height": 13,
"ksize_width": 13,
"min_binary_threshold": 20,
"max_binary_threshold": 255,
"reflection_fill_dilation_index": 25,
"reflection_fill_square_dimension": 200
}
detector = ehdg_pupil_detector.Detector(config=custom_config, reflection_fill_color_index=0, gaussian_blur=True,
binary_fill_hole=True)
for info in detector.get_config_info():
print(f"{info}: {detector.get_config_info()[info]}")
Output will be:
min_circular_ratio: 0.9
max_circular_ratio: 1.9
ksize_height: 13
ksize_width: 13
min_binary_threshold: 20
max_binary_threshold: 255
reflection_fill_dilation_index: 25
reflection_fill_square_dimension: 200
