Opencv 9 resize size change rotate rotate blur mean (blur)

The program implements the Resize Size change Rotate rotate Blur mean value （ Fuzzy ） wave filtering

Simple code , Not in the sharp4 Test above .

Related main functions are as follows ：

Resize Call the following ：

Cv2.Resize(dst, dst,
                                new Size(src.Width + pos, src.Height + pos),
                                interpolation: InterpolationFlags.Cubic);

The last parameter is the interpolation method

Rotate Call the following ：

var imageCenter = new Point2f(src.Cols / 2f, src.Rows / 2f);
            var rotationMat = Cv2.GetRotationMatrix2D(imageCenter, angle, scale);
            Cv2.WarpAffine(src, dst, rotationMat, src.Size());

First, we get the center of rotation

Then construct a structure that contains the center of rotation , angle , Construction matrix of size transformation , Finally, the mapping transformation function is called to realize the rotation operation .

Blur The call is as follows ：

Cv2.GaussianBlur(dst, dst, new Size(pos, pos), sigmaX: 0);

pos Enter an integer number for , Odd number required .
