Interface ImageDistort<Input extends ImageBase,Output extends ImageBase>

All Known Implementing Classes:

public interface ImageDistort<Input extends ImageBase,Output extends ImageBase>
Copies an image onto another image while applying a transform to the pixel coordinates. Pixels outside the source image can be handled using the interpolations border or by simply skipping them. This behavior is set by calling the setRenderAll(boolean) flag. By Default it will render the entire image, even if pixel is outside the source image.

    Modifier and Type
    Method
    Description
    void
    apply(Input srcImg, Output dstImg)

    apply(Input srcImg, Output dstImg, int dstX0, int dstY0, int dstX1, int dstY1)
    Applies the transform to only the specified region inside the destination image.
    void
    apply(Input srcImg, Output dstImg, GrayU8 mask)
    Applies the transform, but marks pixels in the mask as 1 = inside, 0 = outside.

    Specifies how pixel coordinates are transformed from the destination to source images.
    void
    setRenderAll(boolean renderAll)
    Specifies if the entire output image should be rendered, even if mapping to the source image is outside the source image.

  • Method Details

    • setModel

      void setModel(PixelTransform<Point2D_F32> dstToSrc)
      Specifies how pixel coordinates are transformed from the destination to source images.
      Parameters:
      dstToSrc - Pixel coordinate transformation.

    • apply

      void apply(Input srcImg, Output dstImg)
      Applies the transform to the entire destination image.
      Parameters:
      srcImg - (Input) Original image.
      dstImg - (Output) Distorted image.

    • apply

      void apply(Input srcImg, Output dstImg, GrayU8 mask)
      Applies the transform, but marks pixels in the mask as 1 = inside, 0 = outside. Where inside pixels are pixels in the dst image with an equivalent pixel in the src image's bounds
      Parameters:
      srcImg - (Input) Original image.
      dstImg - (Output) Distorted image.
      mask - (Output) Mask of inside pixels. Automatically resized to match dstImg.

    • apply

      void apply(Input srcImg, Output dstImg, int dstX0, int dstY0, int dstX1, int dstY1)
      Applies the transform to only the specified region inside the destination image.
      Parameters:
      srcImg - (Input) Original image.
      dstImg - (Output) Distorted image.
      dstX0 - Left most crop boundary. Inclusive.
      dstY0 - Top most crop boundary. Inclusive.
      dstX1 - Right most crop boundary. Exclusive.
      dstY1 - Bottom most crop boundary. Exclusive.

    • setRenderAll

      void setRenderAll(boolean renderAll)
      Specifies if the entire output image should be rendered, even if mapping to the source image is outside the source image.
      Parameters:
      renderAll - true to render all pixels. If false then only pixels inside the source image

    • getRenderAll

      boolean getRenderAll()
      Returns the render all flag
      Returns:
      render all flag

    • getModel

      PixelTransform<Point2D_F32> getModel()
      Returns the distortion model.
      Returns:
      model dst to src
