phenotypic.tools.funcs_#

phenotypic.tools.funcs_.is_binary_mask(arr: numpy.ndarray)[source]#
Parameters:

arr (numpy.ndarray)

phenotypic.tools.funcs_.is_static_method(owner_cls: type, method_name: str) → bool[source]#

Return True if method_name is defined on owner_cls (or an ancestor in its MRO) as a staticmethod.

Parameters:

  • owner_cls (type)

  • method_name (str)

Return type:

bool

phenotypic.tools.funcs_.murmur3_array_signature(arr: numpy.ndarray) → bytes[source]#

Return a 128‑bit MurmurHash3 digest of arr.

The rgb is converted to a C‑contiguous view so that memoryview can safely expose its buffer. If the rgb is already contiguous this is a zero‑copy operation.

Parameters:

arr (numpy.ndarray)

Return type:

bytes

phenotypic.tools.funcs_.normalize_rgb_bitdepth(image: numpy.ndarray) → numpy.ndarray[source]#

Normalize an RGB rgb to [0,1] using bit-depth inference.

Rules: - If dtype is integer: use dtype max (e.g. 255 for uint8, 65535 for uint16). - If dtype is float:

  • If max <= 1 → assume already normalized, return as-is.

  • If 255 < max <= 65535 → assume 16-bit, divide by 65535.

  • Else → assume 8-bit, divide by 255.

Parameters:

image (numpy.ndarray) – RGB rgb.

Returns:

float64 normalized image in [0,1].

Return type:

np.ndarray

phenotypic.tools.funcs_.timed_execution(func)[source]#

Decorator to measure and print the execution time of a function.

phenotypic.tools.funcs_.validate_measure_integrity(*targets: str)[source]#

Decorator to ensure that key NumPy arrays on the ‘image’ argument are not mutated by an MeasureFeatures.measure() call.

If you pass explicit targets, it will honor those—for example:

@validate_member_integrity(‘image.rgb’)

Otherwise it defaults to checking:

image.rgb, image.gray, image.enh_gray, image.objmap

Parameters:

targets (str)

phenotypic.tools.funcs_.validate_operation_integrity(*targets: str)[source]#

Decorator to ensure that key NumPy arrays on the ‘image’ argument remain unchanged by an ImageOperation.apply() call. If no targets are specified, defaults to checking:

image.rgb, image.gray, image.enh_gray, image.objmap

Example Usage:

@validate_member_integrity(‘image.rgb’, ‘image.objmap’) def func(image: Image,…):

…

Parameters:

targets (str)
