Global threshold with binary/inverted/trunc/tozero semantics, plus OTSU and TRIANGLE auto modes.
Global threshold with binary/inverted/trunc/tozero semantics, plus OTSU and TRIANGLE auto modes.
Swaps rows and columns (mirror across the main diagonal).
Translate/rotate/scale/shear by a 2×3 affine matrix; arbitrary-angle rotation lives here.
Graph boundary for embedded execution: the host binds a value into io_input before running; downstream tasks consume its out port.
Graph boundary for embedded execution: the host collects the graph result from io_output after the run.
Edge-preserving denoise: weights by spatial distance and color difference together.
Box-style mean blur: averages the kernel window — the fastest way to smooth.
Box filter: sums the kernel window (optionally normalized) — the generic form of the mean blur.
Morphological dilation: max over the window — bright regions grow, gaps close.
Morphological erosion: min over the window — bright regions shrink, white specks vanish.
