The subset of axes to determine percentiles jointly,

i.e. axes to reduce to compute min/max from min_percentile/max_percentile. For example to clip 'batch', 'x' and 'y' jointly in a tensor ('batch', 'channel', 'y', 'x') resulting in a tensor of equal shape with clipped values per channel, specify axes=('batch', 'x', 'y'). To clip samples independently, leave out the 'batch' axis.

Only valid if min_percentile and/or max_percentile are set.

Default: Compute percentiles over all axes jointly.

max pydantic-field

max: Optional[float] = None

Maximum value for clipping.

Exclusive with max_percentile.

max_percentile pydantic-field

max_percentile: Optional[
    Annotated[float, Interval(gt=1, le=100)]

config pydantic-field

config: Config

A field for custom configuration that can contain any keys not present in the RDF spec. This means you should not store, for example, a GitHub repo URL in config since there is a git_repo field. Keys in config may be very specific to a tool or consumer software. To avoid conflicting definitions, it is recommended to wrap added configuration into a sub-field named with the specific domain or tool name, for example:

config:
    giraffe_neckometer:  # here is the domain name
        length: 3837283
        address:
            home: zoo
    imagej:              # config specific to ImageJ
        macro_dir: path/to/macro/file

If possible, please use snake_case for keys in config. You may want to list linked files additionally under attachments to include them when packaging a resource. (Packaging a resource means downloading/copying important linked files and creating a ZIP archive that contains an altered rdf.yaml file with local references to the downloaded files.)

EnsureDtypeDescr pydantic-model

Bases: NodeWithExplicitlySetFields

Cast the tensor data type to EnsureDtypeKwargs.dtype (if not matching).

This can for example be used to ensure the inner neural network model gets a different input tensor data type than the fully described bioimage.io model does.

Examples:

The described bioimage.io model (incl. preprocessing) accepts any float32-compatible tensor, normalizes it with percentiles and clipping and then casts it to uint8, which is what the neural network in this example expects. - in YAML

inputs:
- data:
    type: float32  # described bioimage.io model is compatible with any float32 input tensor
  preprocessing:
  - id: scale_range
      kwargs:
      axes: ['y', 'x']
      max_percentile: 99.8
      min_percentile: 5.0
  - id: clip
      kwargs:
      min: 0.0
      max: 1.0
  - id: ensure_dtype  # the neural network of the model requires uint8
      kwargs:
      dtype: uint8

- in Python: >>> preprocessing = [ ... ScaleRangeDescr( ... kwargs=ScaleRangeKwargs( ... axes= (AxisId('y'), AxisId('x')), ... max_percentile= 99.8, ... min_percentile= 5.0, ... ) ... ), ... ClipDescr(kwargs=ClipKwargs(min=0.0, max=1.0)), ... EnsureDtypeDescr(kwargs=EnsureDtypeKwargs(dtype="uint8")), ... ]

Describes a range of valid tensor axis sizes as size = min + n*step.

• min and step are given by the model description.
• All blocksize paramters n = 0,1,2,... yield a valid size.
• A greater blocksize paramter n = 0,1,2,... results in a greater size. This allows to adjust the axis size more generically.

ReproducibilityTolerance pydantic-model

Bases: Node

Describes what small numerical differences -- if any -- may be tolerated in the generated output when executing in different environments.

A tensor element output is considered mismatched to the test_tensor if abs(output - test_tensor) > absolute_tolerance + relative_tolerance * abs(test_tensor). (Internally we call numpy.testing.assert_allclose.)

Motivation

For testing we can request the respective deep learning frameworks to be as reproducible as possible by setting seeds and chosing deterministic algorithms, but differences in operating systems, available hardware and installed drivers may still lead to numerical differences.

axes pydantic-field

axes: Annotated[
    Optional[Sequence[AxisId]],
    Field(examples=[("batch", "x", "y")]),
] = None

The subset of axes to normalize jointly, i.e. axes to reduce to compute the min/max percentile value. For example to normalize 'batch', 'x' and 'y' jointly in a tensor ('batch', 'channel', 'y', 'x') resulting in a tensor of equal shape normalized per channel, specify axes=('batch', 'x', 'y'). To normalize samples independently, leave out the "batch" axis. Default: Scale all axes jointly.

eps pydantic-field

eps: Annotated[float, Interval(gt=0, le=0.1)] = 1e-06

Epsilon for numeric stability. out = (tensor - v_lower) / (v_upper - v_lower + eps); with v_lower,v_upper values at the respective percentiles.

max_percentile pydantic-field

max_percentile: Annotated[float, Interval(gt=1, le=100)] = (
    100.0
)

The upper percentile used to determine the value to align with one. Has to be bigger than min_percentile. The range is 1 to 100 instead of 0 to 100 to avoid mistakenly accepting percentiles specified in the range 0.0 to 1.0.

min_percentile pydantic-field

min_percentile: Annotated[float, Interval(ge=0, lt=100)] = (
    0.0
)

The lower percentile used to determine the value to align with zero.

reference_tensor pydantic-field

reference_tensor: Optional[TensorId] = None

Tensor ID to compute the percentiles from. Default: The tensor itself. For any tensor in inputs only input tensor references are allowed.

SizeReference pydantic-model

Bases: Node

A tensor axis size (extent in pixels/frames) defined in relation to a reference axis.

axis.size = reference.size * reference.scale / axis.scale + offset

Note: 1. The axis and the referenced axis need to have the same unit (or no unit). 2. Batch axes may not be referenced. 3. Fractions are rounded down. 4. If the reference axis is concatenable the referencing axis is assumed to be concatenable as well with the same block order.

Example: An unisotropic input image of wh=10049 pixels depicts a phsical space of 200196mm². Let's assume that we want to express the image height h in relation to its width w instead of only accepting input images of exactly 10049 pixels (for example to express a range of valid image shapes by parametrizing w, see ParameterizedSize).

>>> w = SpaceInputAxis(id=AxisId("w"), size=100, unit="millimeter", scale=2)
>>> h = SpaceInputAxis(
...     id=AxisId("h"),
...     size=SizeReference(tensor_id=TensorId("input"), axis_id=AxisId("w"), offset=-1),
...     unit="millimeter",
...     scale=4,
... )
>>> print(h.size.get_size(h, w))
49

⇒ h = w * w.scale / h.scale + offset = 100 * 2mm / 4mm - 1 = 49

description pydantic-field

description: Annotated[str, MaxLen(128)] = ''

A short description of this axis beyond its type and id.

halo pydantic-field

halo: Annotated[int, Ge(1)]

The halo should be cropped from the output tensor to avoid boundary effects. It is to be cropped from both sides, i.e. size_after_crop = size - 2 * halo. To document a halo that is already cropped by the model use size.offset instead.

id pydantic-field

id: NonBatchAxisId

An axis id unique across all axes of one tensor.

The subset of axes to normalize jointly, i.e. axes to reduce to compute mean/std. For example to normalize 'batch', 'x' and 'y' jointly in a tensor ('batch', 'channel', 'y', 'x') resulting in a tensor of equal shape normalized per channel, specify axes=('batch', 'x', 'y'). To normalize each sample independently leave out the 'batch' axis. Default: Scale all axes jointly.

eps pydantic-field

eps: Annotated[float, Interval(gt=0, le=0.1)] = 1e-06

epsilon for numeric stability: out = (tensor - mean) / (std + eps).
