Opencv Java Rotate Mat

The warpaffine method of the imgproc class applies an affine transformation to the specified image.

Opencv java rotate mat. Src a mat object representing the source input image for this operation. Size a variable of the type integer representing the size of the output image. A transformation that can be expressed in the form of a matrix multiplication linear transformation followed by a vector addition. The warpaffine method of the imgproc class applies an affine transformation to the specified image this method accepts three mat objects representing the source destination and transformation matrices.

Your votes will be used in our system to get more good examples. Theory what is an affine transformation. The following examples show how to use org opencv imgproc imgproc warpaffine these examples are extracted from open source projects.

Opencv calculates the affine matrix that performs affine transformation which means it does not preserve the angle between the lines or distances between the points although it preserves the ratio of distances between points lying on the lines. Rotationmatrix a mat object representing the rotation matrix. This method accepts three mat objects representing the source destination and transformation matrices. Use the opencv function cv warpaffine to implement simple remapping routines.

An integer value representing the size of the output image. The following are jave code examples for showing how to use getrotationmatrix2d of the org opencv imgproc imgproc class. An integer value representing the size of the output image. You can vote up the examples you like.

Use the opencv function cv getrotationmatrix2d to obtain a 2 times 3 rotation matrix.
