_bands | |
_bbox | |
A base component in scarlet lite. Parameters ---------- bands: The bands used when the component model is created. bbox: Box The bounding box for this component.

tuple | bands, | ||
Box | bbox ) |
Reimplemented in lsst.scarlet.lite.io.ComponentCube.
tuple lsst.scarlet.lite.component.Component.bands | ( | self | ) |
The bands in the component model
Box lsst.scarlet.lite.component.Component.bbox | ( | self | ) |
The bounding box that contains the component in the full image
Image lsst.scarlet.lite.component.Component.get_model | ( | self | ) |
Generate a model for the component This must be implemented in inherited classes. Returns ------- model: Image The image of the component model.
Reimplemented in lsst.scarlet.lite.component.FactorizedComponent, lsst.scarlet.lite.io.ComponentCube, and lsst.scarlet.lite.models.parametric.ParametricComponent.
None lsst.scarlet.lite.component.Component.parameterize | ( | self, | |
Callable | parameterization ) |
Convert the component parameter arrays into Parameter instances Parameters ---------- parameterization: Callable A function to use to convert parameters of a given type into a `Parameter` in place. It should take a single argument that is the `Component` or `Source` that is to be parameterized.
Reimplemented in lsst.scarlet.lite.component.FactorizedComponent, lsst.scarlet.lite.io.ComponentCube, and lsst.scarlet.lite.models.parametric.ParametricComponent.
bool lsst.scarlet.lite.component.Component.resize | ( | self, | |
Box | model_box ) |
Test whether or not the component needs to be resized This should be overriden in inherited classes and return `True` if the component needs to be resized.
Reimplemented in lsst.scarlet.lite.component.FactorizedComponent, lsst.scarlet.lite.io.ComponentCube, lsst.scarlet.lite.models.free_form.FreeFormComponent, and lsst.scarlet.lite.models.parametric.ParametricComponent.
None lsst.scarlet.lite.component.Component.update | ( | self, | |
int | it, | ||
np.ndarray | input_grad ) |
Update the component parameters from an input gradient Parameters ---------- it: The current iteration of the optimizer. input_grad: Gradient of the likelihood wrt the component model
