read and view Image

you can start with any programing language but here for simplicity ,

I will start with matlab.

reading Image

image = imread ('coin.pmb');

 image is stored in 'image' array either will be gray level or RGB image.

Change RGB to gray image:

to change it from RGB to gray with loosing data.

          gray_image = unit8(image);

now it will be gray level , with cell values  from 0 to 8. and that will make it easier to handel it in image processing data working.

Show image:

you can show and add labels in the x and y directory and show title of the image by using below commands.

   figure,imshow('gray_image ');

   legend ('Normal Cases' , 'Abnormal Cases');
   xlabel (' X label') ;
   ylabel ('Y label') ;
   title (' here is title');

print image:

to print image after showing automatically in your work-space directory ,you can use below command. 

     print -dpng image.png
