Because of this, the\ncrosstalk is implemented using a generic matrix interpolator, which is\nadded to libipa, in addition to a Matrix class.\n\nv3 mainly adds ccm offsets, and some fixes some initialization and\nasserts.\n\nPaul Elder (3):\n ipa: libipa: Add Matrix class\n ipa: libipa: Add MatrixInterpolator class\n ipa: rkisp1: algorithms: Add crosstalk algorithm\n\n src/ipa/libipa/matrix.cpp | 17 +++\n src/ipa/libipa/matrix.h | 146 +++++++++++++++++++++++++\n src/ipa/libipa/matrix_interpolator.cpp | 54 +++++++++\n src/ipa/libipa/matrix_interpolator.h | 116 ++++++++++++++++++++\n src/ipa/libipa/meson.build | 4 +\n src/ipa/rkisp1/algorithms/ccm.cpp | 116 ++++++++++++++++++++\n src/ipa/rkisp1/algorithms/ccm.h | 44 ++++++++\n src/ipa/rkisp1/algorithms/meson.build | 1 +\n 8 files changed, 498 insertions(+)\n create mode 100644 src/ipa/libipa/matrix.cpp\n create mode 100644 src/ipa/libipa/matrix.h\n create mode 100644 src/ipa/libipa/matrix_interpolator.cpp\n create mode 100644 src/ipa/libipa/matrix_interpolator.h\n create mode 100644 src/ipa/rkisp1/algorithms/ccm.cpp\n create mode 100644 src/ipa/rkisp1/algorithms/ccm.h" }
