DnnInvokeBlobFromImages Method (IInputArrayOfArrays, IOutputArray, Double, Size, MCvScalar, Boolean, Boolean, DepthType)

http://www.emgu.com

Creates 4-dimensional blob from series of images. Optionally resizes and crops images from center, subtract mean values, scales values by scale factor, swap Blue and Red channels.

Parameters

images: Type: Emgu.CVIInputArrayOfArrays
input images (all with 1-, 3- or 4-channels).
blob: Type: Emgu.CVIOutputArray
4-dimensional OutputArray with NCHW dimensions order.
scaleFactor (Optional): Type: SystemDouble
multiplier for images values.
size (Optional): Type: System.DrawingSize
spatial size for output image
mean (Optional): Type: Emgu.CV.StructureMCvScalar
scalar with mean values which are subtracted from channels. Values are intended to be in (mean-R, mean-G, mean-B) order if image has BGR ordering and swapRB is true.
swapRB (Optional): Type: SystemBoolean
flag which indicates that swap first and last channels in 3-channel image is necessary.
crop (Optional): Type: SystemBoolean
flag which indicates whether image will be cropped after resize or not
ddepth (Optional): Type: Emgu.CV.CvEnumDepthType
Depth of output blob. Choose CV_32F or CV_8U.
