Abstract
An apparatus for counting discrete objects of various sizes and shapes as they travel through the apparatus in a disorderly flow. The apparatus includes a sensor array which comprises a plurality of photodetectors arranged in a linear fashion. The discrete objects are passed over the sensor array. By utilizing the sensor array as a means for obtaining information about the discrete objects, the apparatus samples the sensor array at predetermined time intervals, examines the various contours of the images produced through the sampling and based upon predetermined criteria determines whether an image represents one or more objects.
