Metric Options: CountsSelecting 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.

Conference Paper Description
Thin, wide field-of-view HMDs with free-form-surface prism (FFSP) have been widely applied in the fields of Virtual Reality and Augmented Reality. Because the optical distortions affect the quality of the displayed images, distortion correction becomes a key problem. Optical distortions can be corrected with an optical system, but the weight and complexity of the HMDs will be added. In order to overcome such problem, a real-time algorithm based on field-programmable-gate-array (FPGA) for the distortion correction of FFSP-based HMDs is presented in this paper by analyzing the distorted characteristics of the optical system, in which a distorted image with predistortion information is constructed. The framework of the hardware implementation is also presented. The property of the proposed solution is analyzed and verified through a real FFSP-based HMD. Experimental results prove the feasibility of the proposed method. © 2012 Springer-Verlag.
