Abstract: This paper presents an algorithm for identifying a pattern in an image, by using the "cross-correlation" technique. In addition, it shows the difficulties of implementing the algorithm in a video stream context and the solutions applied to remedy these shortcomings. The modified "template matching" algorithm manages to process the image in real-time by using downscaling for restricting the search area.
