XYPRO_RADON

Name


      XYPRO_RADON

Purpose


      A crossi xypro procedure to plot lines from radon points.

Category


Calling Sequence


      xypro_radon, x,y

Inputs


      x,y = x,y coordinates from a radon transform image. in

Keyword Parameters


Keywords


        INIT=win Initialize by giving original image window.
          Only initializes on this call, then returns.
        THICK=thk May specify line thickness when doing INIT.
        /ERASE erase last plotted line, then returns.

Outputs


Common Blocks


      xypro_radon_com

Notes


      Notes: Must have the original image displayed in one
      window and its radon transform displayed in another.
      This routine is used to map from a point in the transform
      display to a line in the original image.
      The following commands can be used to do this interactively.
        Display original image:
          img_disp,img & win1=!d.window
        Do Radon Transform:
          img_radon, img, angle=ang, radius=rd, transform=trans
        Display Radon Transform of image:
          window,/free
          izoom, ang, rd, bytscl(trans),/center
        Explore Radon Transform:
          xypro_radon,init=win1
          crossi,xypro='xypro_radon',/mag
          xypro_radon,/erase
