Class CCheckerDetector

java.lang.Object
org.opencv.core.Algorithm
org.opencv.objdetect.CCheckerDetector
public class CCheckerDetector extends Algorithm
A class to find the positions of the ColorCharts in the image.

  • Constructor Details

    • CCheckerDetector

      protected CCheckerDetector(long addr)

  • Method Details

    • __fromPtr__

      public static CCheckerDetector __fromPtr__(long addr)

    • processWithROI

      public boolean processWithROI(Mat image, MatOfRect regionsOfInterest, int nc)
      Find the ColorCharts in the given image. The found charts are not returned but instead stored in the detector, these can be accessed later on using getBestColorChecker() and getListColorChecker()
      Parameters:
      image - image in color space BGR
      regionsOfInterest - regions of image to look for the chart, if it is empty, charts are looked for in the entire image
      nc - number of charts in the image, if you don't know the exact then keeping this number high helps.
      Returns:
      true if atleast one chart is detected otherwise false

    • processWithROI

      public boolean processWithROI(Mat image, MatOfRect regionsOfInterest)
      Find the ColorCharts in the given image. The found charts are not returned but instead stored in the detector, these can be accessed later on using getBestColorChecker() and getListColorChecker()
      Parameters:
      image - image in color space BGR
      regionsOfInterest - regions of image to look for the chart, if it is empty, charts are looked for in the entire image then keeping this number high helps.
      Returns:
      true if atleast one chart is detected otherwise false

    • process

      public boolean process(Mat image, int nc)
      Find the ColorCharts in the given image. Differs from the above one only in the arguments. This version searches for the chart in the full image. The found charts are not returned but instead stored in the detector, these can be accessed later on using getBestColorChecker() and getListColorChecker()
      Parameters:
      image - image in color space BGR
      nc - number of charts in the image, if you don't know the exact then keeping this number high helps.
      Returns:
      true if atleast one chart is detected otherwise false

    • process

      public boolean process(Mat image)
      Find the ColorCharts in the given image. Differs from the above one only in the arguments. This version searches for the chart in the full image. The found charts are not returned but instead stored in the detector, these can be accessed later on using getBestColorChecker() and getListColorChecker()
      Parameters:
      image - image in color space BGR then keeping this number high helps.
      Returns:
      true if atleast one chart is detected otherwise false

    • create

      public static CCheckerDetector create()
      Returns the implementation of the CCheckerDetector.
      Returns:
      automatically generated

    • create

      public static CCheckerDetector create(Net net)
      Set the net which will be used to find the approximate bounding boxes for the color charts. And returns the implementation of the CCheckerDetector. It is not necessary to use this, but this usually results in better detection rate.
      Parameters:
      net - the neural network, if the network in empty, then the function will return false.
      Returns:
      automatically generated

    • getRefColors

      public Mat getRefColors()
      Gets the reference color for chart.
      Returns:
      automatically generated

    • setDetectionParams

      public void setDetectionParams(DetectorParametersMCC params)
      Sets the detection paramaters for mcc.
      Parameters:
      params - DetectorParametersMCC structure containing detection configuration parameters.

    • setUseDnnModel

      public void setUseDnnModel(boolean useDnn)
      Enables or disables the use of the neural network for detection.
      Parameters:
      useDnn - Boolean flag to indicate whether to use neural network (true) or not (false).

    • getUseDnnModel

      public boolean getUseDnnModel()

    • getDetectionParams

      public DetectorParametersMCC getDetectionParams()
