When you want to use cvtColor() or something method, you should convert CV_64F to 8UC or other suitable Mattype.

mat.ConvertTo(mat, MatType.CV_8UC3); |
Note
This method doesn’t convert some images as shown in this image.
Probably, the MatType property or GetPixel Method is not appropriate in this code.

Mat openCVMat = Cv2.ImRead("hogehoge"); texture2d.LoadImage(openCVMat.ImEncode()); |
