pierogis.ingredients.seasonings.threshold module¶
threshold ingredient(s)
- class pierogis.ingredients.seasonings.threshold.Threshold(opacity: int = 100, mask: Optional[numpy.ndarray] = None, **kwargs)[source]¶
Bases:
pierogis.ingredients.seasonings.seasoning.Seasoning
a seasoning that compares the brightness value of each pixel in the :param target pixel array and sets corresponding colors based on if it is “included” or not
brightness = r * 0.299 + g * 0.587 + b * 0.114
- LOWER_THRESHOLD = 60¶
- UPPER_THRESHOLD = 190¶
- prep(lower_threshold: Optional[int] = None, upper_threshold: Optional[int] = None, inner: bool = False, **kwargs)[source]¶
set the threshold intensity levels
calls Seasoning.prep with leftover kwargs
pixels lower than lower_threshold or higher that upper_threshold are true (include_pixel)
- pixels with brightness >= upper_threshold
or <= lower_threshold are replaced by include pixel (white)
