manualBBdraw_OCC

PURPOSE ^

MANUALBBDRAW_OCC.m produces graphical output for DSKCF tracker

SYNOPSIS ^

function modifiedImage=manualBBdraw_OCC(img,bb,bbOCC,myColor,myColorOCC,lWidth)

DESCRIPTION ^

 MANUALBBDRAW_OCC.m produces graphical output for DSKCF tracker

  MANUALBBDRAW_OCC overlays on top of the current frame the tracker
  bounding box and the one corresponding to the occluding object (if they
  exist) with different color and linewidth

   INPUT:
  -img source image
  -bb target bounding box bounding box in the format [topLeftX, topLeftY,
   bottomRightX, bottomRightY] read as [columnIndexTopLeft, rowIndexTopLeft,
   columnIndexBottomRight, rowIndexBottomRight]

  -bbOCC occluding object bounding box bounding box in the format
  [topLeftX, topLeftY,bottomRightX, bottomRightY] read as
  [columnIndexTopLeft,rowIndexTopLeft, columnIndexBottomRight,
  rowIndexBottomRight]

  -myColor and myColorCC, selected color for the bounding boxes
  -lWidth selected line width for the two bounding boxes

   OUTPUT
  -modifiedImage captured from matlab fig, ready to be saved
