Any I/O pin on any MCU can drive a servo motor, as long as the servo uses a pulse-width or serial input. If you're doing object recognition with a camera, make sure you have plenty of ram to process all the pixels and calculations. Also make sure your MCU can process the type of data coming from the camera chip IE 24-bit color data, SPI, I2C, and any other data processing features that may be required.
I can think of a handful of microcontrollers that would be capable of this kind of function, but it all depends on what features it needs.
