Methods and systems of tracking velocity

A system comprising:

• a processor;
• and
• a computer-readable storage medium storing computer-readable instructions which, when executed by the processor, cause the processor to perform steps comprising:
• receiving image data of the fluid or the object, the image data comprising a plurality of frames, wherein each frame comprises an array of pixel values;
• creating an image using frame differencing by subtracting an array of pixel values for a first frame of the image data from an array of pixel values for a second frame of the image data;
• utilizing the image created with frame differencing to determine a location of the object or one or more objects within the fluid;
• utilizing a correlation or a convolution to determine a distance traveled by the object or the one or more objects within the fluid between two or more frames;
• and
• based on the distance traveled by the object or the one or more objects within the fluid, automatically determine the velocity of the fluid or the object.

A computer program product comprising:

• a non-transitory computer readable storage medium having computer readable program code embodied therewith, the computer readable program code configured when executed by a processor to perform steps comprising:
• receiving image data of the fluid or the object, the image data comprising a plurality of frames, wherein each frame comprises an array of pixel values;
• creating an image using frame differencing by subtracting an array of pixel values for a first frame of the image data from an array of pixel values for a second frame of the image data;
