Stereo Rectification ===================== Performs stereo rectification on the input images Input ----- Two 2D image sets representing the left and the right camera view. The images must contain a :ref:`camera calibration data component`. Output ------ Rectified stereo images Description ----------- The algorithm performs stereo rectification based on the provided camera calibration information for the stereo pair. The registration matrix of the left image must be identity. The following parameters are supported: **Alpha** - Specifies whether all pixels in the output image should be valid (alpha = 0) or whether the entire input image should be mapped (alpha = 1). This generally results in some black areas in the rectified images. Values between 0 and 1 create an intermediate state, -1 automatically chooses alpha.
