Transforms an image to GrayScale as an image processing unit.
Supported color spaces:
The conversion is based on OpenCV RGB to GRAY conversion https://docs.opencv.org/master/de/d25/imgproc_color_conversions.html#color_convert_rgb_gray

TransformToGrayscaleOp()
Creates a TransformToGrayscaleOp.

| int |
getOutputImageHeight(int inputImageHeight, int inputImageWidth)
Computes the height of the expected output image when input image size is given.
|
| int |
getOutputImageWidth(int inputImageHeight, int inputImageWidth)
Computes the width of the expected output image when input image size is given.
|
| PointF |
inverseTransform(PointF point, int inputImageHeight, int inputImageWidth)
Transforms a point from coordinates system of the result image back to the one of the input
image.
|
Creates a TransformToGrayscaleOp.
Applies the transformation to grayscale and returns a TensorImage.
If the input image is already ColorSpaceType.GRAYSCALE, this op will be a no-op.
