Parameters

cameraMatrix: Type: OpenCvSharpCvMat
The input camera matrix
distCoeffs: Type: OpenCvSharpCvMat
The input 4x1, 1x4, 5x1 or 1x5 vector of distortion coefficients (k_1, k_2, p_1, p_2[, k_3])
imageSize: Type: OpenCvSharpCvSize
The original image size
alpha: Type: SystemDouble
The free scaling parameter between 0 (when all the pixels in the undistorted image will be valid) and 1 (when all the source image pixels will be retained in the undistorted image);
newCameraMatrix: Type: OpenCvSharpCvMat
The output new camera matrix.
newImageSize: Type: OpenCvSharpCvSize
The image size after rectification. By default it will be set to imageSize .
validPixROI: Type: OpenCvSharpCvRect
The optional output rectangle that will outline all-good-pixels region in the undistorted image.
