## About This Module

The NVIDIA<sup>&reg;</sup> DriveWorks Connected Components module applies connected components labeling algorithm to a grey scale input image. The image is binarized with specified threshold and unique label is assigned to every connected region.

## Limitations

Module has the following limitations:

* both width and height of an input image should be less or equal to 2048 pixels
* the input should be a pitch linear CUDA image
* the format of an input image should be one of `::DW_IMAGE_FORMAT_R_UINT8`, `::DW_IMAGE_FORMAT_YUV420_UINT8_PLANAR` or `::DW_IMAGE_FORMAT_YUV_UINT8_PLANAR`
