1. A method, comprising:
receiving a series of captured images of a particular scene over a time period;
identifying a first pixel in each captured image of the series of captured images, wherein the first pixel in each captured image of the series of captured images is associated with a pixel coordinate;
determining a set of pixel values, including a pixel value for each first pixel in each captured image of the series of captured images;
eliminate a first predetermined number of top pixel values and a second predetermined number of bottom pixel values from the set of pixel values to form a modified set of pixel values;
determining a median pixel value of the modified set of pixel values;
associating the median pixel value with the pixel coordinate of a resulting image; and
determining the first predetermined number of top pixel values and the second predetermined number of bottom pixel values based on one of a number of false alarms detected and an environmental factor.
