Diagnostics of accelerator beams using TV cameras to observe the beam spot is quite common. Several software algorithms like those based on the work of Sobel, Roberts, Prewitt, Marr-Hildreth, and Canny are applied to the captured image to yield a binary image. For the present purpose, the Canny algorithm is found to produce by far the best result and the data obtained is suggestive of further implementation in similar fields of research.
