template<typename OutImageT, typename InImageT>
void lsst::afw::math::detail::basicConvolve(OutImageT &convolvedImage, InImageT const &inImage, lsst::afw::math::Kernel const &kernel, lsst::afw::math::ConvolutionControl const &convolutionControl)

Low-level convolution function that does not set edge pixels.

convolvedImage must be the same size as inImage. convolvedImage has a border in which the output pixels are not set. This border has size:

  • kernel.getCtrX() along the left edge

  • kernel.getCtrY() along the bottom edge

  • kernel.getWidth() - 1 - kernel.getCtrX() along the right edge

  • kernel.getHeight() - 1 - kernel.getCtrY() along the top edge

Parameters

  • [out] convolvedImage: convolved image

  • [in] inImage: image to convolve

  • [in] kernel: convolution kernel

  • [in] convolutionControl: convolution control parameters

Exceptions

  • lsst::pex::exceptions::InvalidParameterError: if convolvedImage dimensions != inImage dimensions

  • lsst::pex::exceptions::InvalidParameterError: if inImage smaller than kernel in width or height

  • lsst::pex::exceptions::InvalidParameterError: if kernel width or height < 1

  • std::bad_alloc: when allocation of CPU memory fails
