public class VisualizeImageData extends Object
Renders different primitive image types into a BufferedImage for visualization purposes.

      public VisualizeImageData()

  • Method Details

    • standard

      public static BufferedImage standard(ImageGray<?> src, BufferedImage dst)

    • colorizeSign

      public static BufferedImage colorizeSign(ImageGray src, @Nullable @Nullable BufferedImage dst, double normalize)

      Renders a colored image where the color indicates the sign and intensity its magnitude. The input is divided by normalize to render it in the appropriate scale.

      Parameters:
      src - Input single band image.
      dst - Where the image is rendered into. If null a new BufferedImage will be created and return.
      normalize - Used to normalize the input image. If ≤ 0 then the max value will be used
      Returns:
      Rendered image.

    • grayUnsigned

      public static BufferedImage grayUnsigned(GrayI src, BufferedImage dst, int normalize)

    • grayMagnitude

      public static BufferedImage grayMagnitude(ImageGray src, @Nullable @Nullable BufferedImage dst, double normalize)

      Renders a gray scale image of the input image's intensity.

      dst(i,j) = 255*abs(src(i,j))/normalize

      Parameters:
      src - Input single band image.
      dst - Where the image is rendered into. If null a new BufferedImage will be created and return.
      normalize - Used to normalize the input image. If < 0 then this value is automatically computed.
      Returns:
      Rendered image.

    • grayMagnitudeTemp

      public static void grayMagnitudeTemp(ImageGray src, BufferedImage dst, double normalize)

      Renders a gray scale image using color values from cold to hot.

      Parameters:
      src - Input single band image.
      dst - Where the image is rendered into. If null a new BufferedImage will be created and return.
      normalize - Used to normalize the input image.

    • disparity

      public static BufferedImage disparity(ImageGray disparity, @Nullable @Nullable BufferedImage dst, int disparityRange, int invalidColor)

      Renders a gray scale image using color values from cold to hot.

      Parameters:
      disparity - Input disparity image
      dst - Where the image is rendered into. If null a new BufferedImage will be created and return.
      disparityRange - Number of possible disparity values
      invalidColor - RGB value for invalid pixels. Try 0xFF << 8 for green
      Returns:
      Rendered image.

    • inverseDepth

      public static BufferedImage inverseDepth(GrayF32 src, @Nullable @Nullable BufferedImage dst, float maxValue, int invalidColor)
      Colorizes an inverse depth image.
      Parameters:
      src - Inverse depth image
      dst - Output rendering
      maxValue - Max possible value. Reminder that larger means closer
      invalidColor - What color to mark pixels with no depth info
      Returns:
      rendered image

    • inverseDepth

      public static BufferedImage inverseDepth(GrayF32 src, @Nullable @Nullable BufferedImage dst, float minValue, float maxValue, int invalidColor)
      Colorizes an inverse depth image.
      Parameters:
      src - Inverse depth image
      dst - Output rendering
      minValue - Minimum possible value. Reminder that larger means closer. If < 0.0f it will auto select
      maxValue - Max possible value. Reminder that larger means closer. If <= 0.0f it will auto select
      invalidColor - What color to mark pixels with no depth info
      Returns:
      rendered image

    • graySign

      public static BufferedImage graySign(GrayF32 src, @Nullable @Nullable BufferedImage dst, float maxAbsValue)

    • colorizeGradient

      public static BufferedImage colorizeGradient(ImageGray derivX, ImageGray derivY, double maxAbsValue, BufferedImage output)
      Renders two gradients on the same image using two sets of colors, on for each input image.
      Parameters:
      derivX - (Input) Image with positive and negative values.
      derivY - (Input) Image with positive and negative values.
      maxAbsValue - The largest absolute value of any pixel in the image. Set to < 0 if not known.
      Returns:
      visualized gradient
