Abstract

Systems and methods for determining a velocity of a fluid or an object are described. Systems and methods include receiving image data of the fluid or the object, the image data comprising a plurality of frames. Each frame comprises an array of pixel values. Systems and methods include creating a frame difference 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. Systems and methods include measuring a difference between a location of the object in the first frame of the image data and the second frame of the image data. Systems and methods include creating a correlation matrix based on the measured difference. Systems and methods include using the frame difference and the correlation matrix to automatically determine the velocity of the fluid or the object.
