io_output · Graph boundary output
Graph boundary for embedded execution: the host collects the graph result from io_output after the run.
Node-Guide
opencv_bilateral_filter · Bilateral filter
Edge-preserving denoise: weights by spatial distance and color difference together.
opencv_blur_filter · Box blur
Box-style mean blur: averages the kernel window — the fastest way to smooth.
opencv_box_filter · Box filter
Box filter: sums the kernel window (optionally normalized) — the generic form of the mean blur.
opencv_dilate · Dilate
Morphological dilation: max over the window — bright regions grow, gaps close.
opencv_erode · Erode
Morphological erosion: min over the window — bright regions shrink, white specks vanish.
opencv_filter_2d · Custom convolution
2D convolution with any kernel you write down as a numeric matrix.
opencv_gabor_filter · Gabor filter
Directional texture filtering with Gabor kernels — a classic for fingerprint/fabric analysis.
opencv_gaussian_blur_filter · Gaussian blur
Gaussian-weighted blur: natural smoothing, the default choice for denoising.
opencv_image_read · Read image
Reads one image from disk (png / jpg / bmp / tiff / webp …) as the graph’s input source.
