Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
This paper proposes an absolute phase retrieval using one additional coding pattern to measure the complex object. Compared with traditional temporal phase unwrapping (TPU) methods, the proposed coding pattern is generated from phase-shifting patterns and the phase difference rather than stair stripes containing different quantified gray-level. In this paper, N -step phase-shifting profilometry (PSP) can provides 2 N codewords, which can be used to label the large number of fringe orders. To ensure measuring accuracy, the errors closed to turning points can be identified by quantified phase difference, and then compensated. Experimental results demonstrate that the proposed method can achieve the same level of measuring accuracy as the classical PSP, and has strong robustness on the measurement of the object with sharp and colorful surfaces. The dynamic experiment shows that the proposed method only requiring one additional pattern can achieve the 3-D reconstructed rate of 30 fps.
