a way to compare two images by finding out the degree of difference b/w them
That is a really open ended question that will need a lot of clarification.
For example:
- What degree of similarity would you ascribe to these two images? A, B
These two are from a 'spot the differences' competition and have 10 substantial differences. Elements have changed color; things have changed position.
How similar do you want to consider the two?
- How about these two? A, B
This is more subtle. The two images are identical in their content, but the color of every pixel in the picture is slightly different. So if you do a simple numerical comparison, they would be rated as 100% different.
Do you want them assessed as 100% different?
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
