BackgroundImage2d
Computes a background image from a grayscale image.
Access to parameter description
This algorithm estimates a background by interpolating all pixels contained in a binary mask by a second order polynomial. If no mask is provided, all the image pixels are considered for performing the interpolation.

Parameters
| Parameter Name | Description | Type | Supported Values | Default Value | |
|---|---|---|---|---|---|
 |
inputImage |
The input image. | Image | Grayscale or Multispectral | nullptr |
|
inputMaskImage |
The binary mask image for the polynomial interpolation. If it equals null, the background is computed from all pixels of the input image. This image must have same dimensions as the input image. | Image | Binary | nullptr |
 |
outputImage |
The output image. Its dimensions and type are forced to the same values as the input. | Image | nullptr | |
| Parameter Name | Description | Type | Supported Values | Default Value | |
|---|---|---|---|---|---|
|
input_image |
The input image. | image | Grayscale or Multispectral | None |
|
input_mask_image |
The binary mask image for the polynomial interpolation. If it equals null, the background is computed from all pixels of the input image. This image must have same dimensions as the input image. | image | Binary | None |
|
output_image |
The output image. Its dimensions and type are forced to the same values as the input. | image | None | |
| Parameter Name | Description | Type | Supported Values | Default Value | |
