Barrel Blob Finder

A barrel and its bounding box, as identified by BarrelBlobFinder

BarrelBlobFinder is an ImageFilterDemo filter that identifies orange/white construction barrels in an input image.

Input

• Image whose pixels are in ARGB format.
  • width : int
  • height : int
  • pixels : int[]

Output

• List of boundary rectangles for the barrels identified in the input image, in the coordinate space of the input image.
  • barrelBoundList : List<Rectangle>

Production Version

• The BarrelBlobFinder algorithm has been integrated into the final production code.
• Since its integration, the production version of BarrelBlobFinder has had some unique modifications made to it.
  • Pixels identified as orange/white by the filter are painted solid orange/white respectively on the output image.
  • Tick marks on the side of identified barrel bounds show the size of the minimum detectable barrel.
  • Slanted lines inside each identified barrel bound show the maximum rate of tapering that the detector will tolerate.
  • A badge icon in the lower left hand corner shows the prototypical minimum-size barrel that the detector will pick up.
