Abstract

A system for regulating fluid flow having a processor configured to reduce image noise is provided. The system includes an image sensor to capture an image of the drip chamber. The processor captures the image of the drip chamber using the image sensor, performs an edge detection on the image to generate a first processed image, and performs a Boolean-operation on a pixel on a first side of an axis of the first processed image with a corresponding pixel on a second side of the axis of the first processed image to generate a second processed image.
