Scalar with mean values which are subtracted from channels. | |
ImagePaddingMode | paddingmode |
Image padding mode. | |

Processing params of image to blob.
It includes all possible image processing operations and corresponding parameters.
scalefactor
and mean
are (input - mean) * scalefactor. The order and usage of scalefactor
, size
, mean
, swapRB
, and ddepth
are consistent with the function of blobFromImage. cv::dnn::Image2BlobParams::Image2BlobParams | ( | ) |
