PART - I(color)
 

  The  image in the left column is the given color image ( converted into .gif format from the given
  .ppm format) .  The Second and Third coloumn contain the images mapped in grayscale using the
  Intensity model  and  Luminance model  respetively , which are output of the program  grey.c .
  The images in the second and third column  are in .gif format (converted from .pgm format produced
  by the program "grey.c" .
 
 
 

The Original  color                  image	The  Intensity  Grayscale                  mapped   image	The Luminance Grayscale          mapped  image

                                                   PART - II ( edge detection)
 
  In this section I present the EDGE DETECTION using Canny's filter on this
  image. The source code for this program is in    edge.c .

    The results are shown in the following three TABLES . They  contain best of the   three  images       for  sigma = 1 , 2 and 4 respectively .
 

Sigma = 1 , threshold=8	Sigma=1, threshold=8.5	Sigma=1, threshold=9.0

Sigma = 2, threshold=3	Sigma=2, threshold=3.5	Sigma=2, threshold=4

Sigma=4,threshold=1.25	Sigma=4, threshold=1.5	Sigma=4,threshold=1.75

 
    The Filter  is of 2*sigma + 1  in length in both  its width and height.
