public interface ImageOperator

| Known Indirect Subclasses

ResizeOp, ResizeWithCropOrPadOp, Rot90Op, TensorOperatorWrapper, TransformToGrayscaleOp

| ResizeOp | As a computation unit for processing images, it can resize an image to user-specified size. | | ResizeWithCropOrPadOp | As a computation unit for processing images, it could resize image to predefined size. | | Rot90Op | Rotates image counter-clockwise. | | TensorOperatorWrapper | The adapter that makes a TensorOperator able to run with TensorImage. | | TransformToGrayscaleOp | Transforms an image to GrayScale as an image processing unit. |

|

Operates a TensorImage object. Used in ImageProcessor.

Public Methods

| abstract TensorImage | apply(TensorImage image) | | abstract int | getOutputImageHeight(int inputImageHeight, int inputImageWidth) Computes the height of the expected output image when input image size is given.

| | abstract int | getOutputImageWidth(int inputImageHeight, int inputImageWidth) Computes the width of the expected output image when input image size is given.

| | abstract 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.
