Codex:

Removes a callback function from a filter hook.

This can be used to remove default functions attached to a specific filter hook and possibly replace them with a substitute. To remove a hook, the $callback and $priority arguments must match when the hook was added. This goes for both filters and actions. No warning will be given on removal failure.
