What you are looking for is an "object recognition" algorithm. These algorithms take one or multiple images of an object (e.g. your little statue) and then try to locate it in another image. Generally, they are computationally expensive, so performing them on a video stream, especially inside the browser, will most likely not work, even for rather low resolutions. I have some experience with the SIFT algorithm. Takes some time to grok it as the algorithm consists of several sub-steps. You may want to look into OpenCV, they have a couple of algorithms implemented.
