USB camera interfacing

So, first I'm going to say, I've done research on this topic and couldn't seem to find anything about it that could help me. Anywho, I'm wanting to try and use a USB webcam with my Arduino but can only use USB so I'm wanting to make my Arduino into a USB host only using my Arduino Uno and my power supply module to do so, is this a possible thing to do or do I need second/and third party(s) to do so? as I said I'm working with the Arduino Uno.

is this a possible thing to do

Without extra hardware, no.

do I need second/and third party(s) to do so?

You need a USB host shield AND you need to write the necessary USB driver.

Or, you need to get a Raspberry Pi.

Thanks for your response. I might get the shield then.
