ConvertScale

Prerequisites:

  • bonsai Dsp Library

Category: Transform

Brief: Converts the input array into the specified bit depth with optional linear transformations.

Input (OpenCV.Net.Mat, OpenCV.Net.IplImage, ...) - an array

Properties:

  • Depth(System.Nullable<OpenCV.Net.Depth>) - target bit depth of individual array elements (optional, can choose from U8, S8, U16, S16, S32, F32, F64); if left empty, leaves the input depth unchanged
  • Scale (double) - scale factor applied to individual array elements (optional)
  • Shift (double) - value to be added to individual array elements (optional)

Output (OpenCV.Net.Mat, OpenCV.Net.IplImage, ...) - an array of the same shape and type as the input array

tip

ConvertScale with Scale = 0 can be used to stop input transmission, e.g. to drive pins/ports to LOW state at the end of a workflow

tip

Use ConvertScale to convert image data with depth greater than 8 bits to U8, which is accepted as input by VideoWriter. Scale and Shift arguments can be set accordingly (based on the expected pixel range) to maintain image appearance as much as possible.
