Interface ImageMotion2D<I extends ImageBase<I>,IT extends InvertibleTransform>

Type Parameters:
I - Input image type
IT - Internally used image motion model
All Known Implementing Classes:
PlToGrayMotion2D, WrapImageMotionPtkSmartRespawn
public interface ImageMotion2D<I extends ImageBase<I>,IT extends InvertibleTransform>
Estimates the 2D motion of images in a video sequence. All internal motion models must belong to the Homography2D_F64 transformation family, The returned transformations use the first image as the reference frame, but other images can be converted into the reference frame. Typically used in image stabilization or image mosaic applications.

  • Method Summary

    Modifier and Type
    Method
    Description
    IT
    getFirstToCurrent()
    Transform from first image into the current image.
    long
    getFrameID()
    Returns the ID of the most recently processed frame.
    Class<IT>
    getTransformType()
    Type of transform that it estimates
    boolean
    process(I input)
    Processes and updates the image transform.
    void
    reset()
    Resets the class into its initial state and throws away any information on the image sequence
    void
    setToFirst()
    Turns the current image into the origin of the coordinate system.

  • Method Details

    • process

      boolean process(I input)
      Processes and updates the image transform. The very first image processed will always return true and have a transform of no motion.
      Parameters:
      input - Next image in the sequence. Not modified.
      Returns:
      true if the transform has been updated and false if not

    • reset

      void reset()
      Resets the class into its initial state and throws away any information on the image sequence

    • setToFirst

      void setToFirst()
      Turns the current image into the origin of the coordinate system.

    • getFrameID

      long getFrameID()
      Returns the ID of the most recently processed frame. Starts at zero and increments with each call to process.

    • getFirstToCurrent

      IT getFirstToCurrent()
      Transform from first image into the current image. NOTE: Returned transform is owned by this class and can be modified after any function is called.
      Returns:
      Image transform

    • getTransformType

      Class<IT> getTransformType()
      Type of transform that it estimates
      Returns:
      Transform type.
