manualBBdraw_MULTIPLE

PURPOSE ^

MANUALBBDRAW_MULTIPLE.m function that produces graphical output for DSKCF tracker

SYNOPSIS ^

function modifiedImage=manualBBdraw_MULTIPLE(img,bbVector,myColor,lWidth,myText1,myTextColor)

DESCRIPTION ^

 MANUALBBDRAW_MULTIPLE.m function that produces graphical output for DSKCF tracker

  MANUALBBDRAW_MULTIPLE overlays on top of the current frame a
  vector of bounding boxes (if they exist) with different color and
  linewidth. Also a text is displayed on the top left corner of the image

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


  -myColor selected color for the bounding boxes
  -lWidth selected line width for the bounding boxes
  -myText1 list containing text corresponding to the bounding boxes
  displayed (with the selected color) on the top left of the image

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