ImageProcessor class

ImageProcessor is a helper class for preprocessing and postprocessing TensorImage.

It could transform a TensorImage to another by executing a chain of ImageOperator.

Example Usage:

  ImageProcessor processor = ImageProcessorBuilder()
      .add(ResizeOp(224, 224, ResizeMethod.NEAREST_NEIGHBOR)
      .add(Rot90Op())
      .add(NormalizeOp(127.5, 127.5))
      .build();
  TensorImage anotherTensorImage = processor.process(tensorImage);

See ImageProcessorBuilder to build a ImageProcessor instance

See SequentialProcessor.process to apply the processor on a TensorImage

Properties

hashCode → int

The hash code for this object.

no setter, inherited

operatorIndex ↔ Map<String, List<int>>

The Map between the operator name and the corresponding op indexes in operatorList. An operator may be added multiple times into this SequentialProcessor.

Methods

inverseTransform(Point<num> point, int inputImageHeight, int inputImageWidth) → Point<num>

Transforms a point from coordinates system of the result image back to the one of the input image.

inverseTransformRect(Rect rect, int inputImageHeight, int inputImageWidth) → Rect

Transforms a rect from coordinates system of the result image back to the one of the input image.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.
