The University of Houston is a state research university and the flagship institution of the University of Houston System. Founded in 1927, UH is Texas's third-largest university with nearly 41,000 students. Its campus spans 667 acres in southeast Houston, and was known as University of Houston–University Park from 1983 to 1991. The Carnegie Foundation classifies UH as a Tier One research university. The U.S. News & World Report ranks the university No. 189 in its National University Rankings, and No. 106 among top public universities.The university offers over 300 degree programs through its 12 academic colleges on campus—including programs leading to professional degrees in law, optometry, and pharmacy. The institution conducts nearly $130 million annually in research, and operates more than 40 research centers and institutes on campus. Interdisciplinary research includes superconductivity, space commercialization and exploration, biomedical science and engineering, energy and natural resources, and artificial intelligence. Awarding more than 8,200 degrees annually, UH's alumni base exceeds 260,000. The economic impact of the university contributes over $3 billion annually to the Texas economy, while generating about 24,000 jobs.The University of Houston hosts a variety of theatrical performances, concerts, lectures, and events. It has over 400 student organizations and 17 intercollegiate sports teams. Annual UH events and traditions include The Cat's Back, Homecoming, and Frontier Fiesta. The university's varsity athletic teams, known as the Houston Cougars, are members of the American Athletic Conference and compete in the NCAA's Division I in all sports. The football team regularly makes bowl game appearances, and the men's basketball team has made 19 appearances in the NCAA Division I Tournament—including five Final Four appearances. The men's golf team has won 16 national championships—the second-most of any NCAA golf program. Wikipedia.

We put forth an algorithm to track isolated micron-size solid and liquid particles that produce time-dependent asymmetric intensity patterns. This method quantifies the displacement of a particle in the image plane from the peak of a spatial cross-correlation function with a reference image. The peak sharpness results in subpixel resolution. We demonstrate the utility of the method for tracking liquid droplets with changing shapes and micron-size particles producing images with exaggerated asymmetry. We compare the accuracy of diffusivity determination with particles of known size by this method to that by common tracking techniques and demonstrate that our algorithm is superior. We address several open questions on the characterization of diffusive behaviors. We show that for particles, diffusing with a root-mean-square displacement of 0.6 pixel widths in the time between two successive recorded frames, more accurate diffusivity determinations result from mean squared displacement (MSD) for lag times up to 5 time intervals and that MSDs determined from non-overlapping displacements do not yield more accurate diffusivities. We discuss the optimal length of image sequences and demonstrate that lower frame rates do not affect the accuracy of the estimated diffusivity.
