ComfyUI Node
CV Identity Map
The starting point of every remap chain: the do-nothing coordinate grid sized like the given image (map_x[y][x] = x, map_y[y][x] = y). Feed it through distortion-map nodes (radial lens, cylinder, pinch, wave, displacement, homography) - each rewrites the coordinates, so chaining composes distortions - and apply the final pair with the low-level cv2_remap.

Inputs (1)
| Name | Type | Default | Description |
|---|---|---|---|
| image | NPARRAY,IMAGE,MASK | Only its width/height are used. 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. |
Outputs (2)
| Name | Type | Description |
|---|---|---|
| map_x | NPARRAY | HxW float32 source-x coordinate per pixel. |
| map_y | NPARRAY | HxW float32 source-y coordinate per pixel. |
