Hello rudra,
I think these case studies might be interesting for you:

It might also be a good idea to start by taking a look at the IMAQ VI's, like for example:

Also interesting might be this thread:

Thank you very much sir for the help. i have another doubt. for a given image what will be its dimension. i mean if the pixel value of the image consists of an array of size 20*20 then then what will be the dimension of that image???

Hello Rudra386,
What do you mean exactly with its dimension?
Do you mean how big it will be (size) on the screen?
I this is your concern, then please keep in mind that you can always "zoom in" on an image:

This is just one way to do this.
There also some nice examples available online that concern the zooming of images:

thanks a lot sir .sir how do i insert a null value into an array.i tried but still zero values are automatically assigned to the rows in the array.ive attached the vi and im using labview 2010 version.idont hv a version 11.sir i need to avoid the zero rows from the arrays D1 and D2.

sorry sir im sending the vi again coz the previous one had reference values.

Hello rudra,
I don't really get what you're trying to do.
Are you trying to insert a "NULL" value inside your array?
Or do you just want to write either to one array or to the other, depending on the results of the comparison?
Kind Regards,

yes sir.. i want to write either to one array or to the other, depending on the results of the comparison..
