lsst.afw.math¶
lsst.afw.math
provides mathematical functions such as convolution and image statistics.
Key features:
- Function objects
FunctionF
andFunctionD
Statistics
Background
estimation of images.Interpolate
Kernel
- Optimization of functions is handled by
minimize()
- Convolution of images is handled by
convolve()
- Warping of images is handled by
warpImage()
- Manipulating spatially-distributed sets of objects (e.g. PSF candidates)
