Note

SW Release Applicability: This module is available in both NVIDIA DriveWorks and NVIDIA DRIVE Software releases.

About This Module

The NVIDIA^® 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
