Class ImageCoverage

java.lang.Object
boofcv.alg.misc.ImageCoverage

public class ImageCoverage
extends Object
Computes the fraction / percent of an image which is covered by image features. Converage is computed by overlaying a grid on top of the image. The size of a cell depends on the maximum number of possible features which can be detected.

    • reset

      public void reset​(int maxFeatures, int width, int height)
      Resets and adjusts the grid size
      Parameters:
      maxFeatures - Maximum number of features which can be inside an image
      width - image width
      height - image height
    • markPixel

      public void markPixel​(int pixelX, int pixelY)
      Marks a pixel in the image as having contained a feature. The pixel must lie inside the image. Outside pixels have undefined and likely very bad behavior.
    • process

      public void process()
