I followed below steps to show captcha in login and registration form. But I can't see it.
Login to backend
Go to system > configuration > customers > customer configuration > CAPTCHA and select your website scope
Enable CAPTCHA on frontend – Yes
Select all forms into Form box
In Displaying Mode box select After number of attempts to login
Number of Unsuccessful Attempts to Login = 0
Save Config
Go to frontend and press Log in link
Is there any thing else left to enable captcha in login or registration form…

You might have the Mage_Captcha module disabled.
Go to System > Configuration > Advanced > Disable modules output and make sure it is not disabled.
Another thing to check is the modules configuration file:
app/etc/modules/Mage_Captcha.xml.
Make sure it is set to active:
<active>true</active>
