Function Documentation

◆cudaCrop() [1/7]

| cudaError_t cudaCrop | ( | float * | input, | | | | float * | output, | | | | const int4 & | roi, | | | | size_t | inputWidth, | | | | size_t | inputHeight | | | ) | | |

Crop a floating-point grayscale image to the specified region of interest (ROI).

Parameters

| [in] | input | Pointer to the input image in CUDA memory. | | [out] | output | Pointer to the output image in CUDA memory. The output image should have the same dimensions as the ROI. | | | roi | The region of interest from the input image that will be copied to the output image. This int4 vector forms a crop rectangle as follows: |

  • roi.x -> left
  • roi.y -> top
  • roi.z -> right
  • roi.w -> bottom

The ROI coordinates must not be negative, otherwise an error will be returned.

Parameters

| inputWidth | width of the input image (in pixels) | | inputWidth | height of the input image (in pixels) |

◆cudaCrop() [2/7]

This int4 vector forms a crop rectangle as follows: |

  • roi.x -> left
  • roi.y -> top
  • roi.z -> right
