ComfyUI Node
cv2.filter2D
Raw wrapper of cv2.filter2D(src, ddepth, kernel, anchor?, delta?, borderType?). Parameters marked '?' are optional; blank means OpenCV default. See the OpenCV documentation for details.

Inputs (6)
| Name | Type | Default | Description |
|---|---|---|---|
| src | COMFY_MATCHTYPE_V3 | input image. The image output(s) echo this input's format. A LATENT link is processed in latent space: frame 0 becomes a float32 [H,W,C] array (any channel count), values untouched. Arithmetic ops (add, multiply, etc.) also accept a full LATENT batch ({samples: [B,C,H,W]}) — the whole batch flows through when both inputs have the same batch size. Accepts a ComfyUI IMAGE/MASK directly (frame 0 of a batch) or an NPARRAY. Arithmetic ops (add, multiply, etc.) process the full IMAGE batch when both inputs have the same batch size. | |
| ddepth | COMBO | same as input | desired depth of the destination image, see "combinations" |
| kernel | NPARRAY | convolution kernel (or rather a correlation kernel), a single-channel floating point matrix; if you want to apply different kernels to different channels, split the image into separate color planes using split and process them individually. A data array (points / matrix), NOT an image - only an NPARRAY link is accepted here. | |
| anchoropt | CV_TUPLE | -1,-1 | anchor of the kernel that indicates the relative position of a filtered point within the kernel; the anchor should lie within the kernel; default value (-1,-1) means that the anchor is at the kernel center. One value with 2 components (x, y) - it travels as a whole, so it cannot arrive half-connected. Wire it from 'CV Tuple' or type the components in place. |
| deltaopt | FLOAT | 0.0000-1e+38–1e+38 | optional value added to the filtered pixels before storing them in dst. Preset to the OpenCV default (0.0). |
| borderTypeopt | COMBO | BORDER_DEFAULT | pixel extrapolation method, see #BorderTypes. #BORDER_WRAP is not supported. |

| Name | Type | Description |
|---|---|---|
| result | COMFY_MATCHTYPE_V3 | Echoes the 'src' input's format: an IMAGE link comes back as IMAGE, MASK as MASK, NPARRAY stays NPARRAY. |
