Expectation-maximization (EM) algorithm All analyses were performed using R50 in RStudio51; the package ‘mixtools’52 was employed to apply a GMM to the VLP areas or widths extracted from the AFM images. Convergence of the EM algorithm was capped at 1000 iterations. A function to construct ...
We assessed the performance of Kalman Filtering-Smoothing and Expectation Maximization (EM-KF) in gap filling snow-depth sensor data. To this end, hourly snow-depth data from three spatially dense wireless-sensor networks were randomly removed and imputed using EM-KF. Maximum gap size was 40+ ...
Dense Photometric Stereo by Expectation Maximization Tai-Pang Wu and Chi-Keung Tang Vision and Graphics Group, The Hong Kong University of Science and Technology, Clear Water Bay, Hong Kong Abstract. We formulate a robust method using Expectation Maximiza- tion (EM) to address the problem of ...
(FDK) algorithm) or iterative methods. Analytical schemes are typically computationally more efficient and hence preferred for large datasets such as digital rocks. Iterative schemes like maximum likelihood expectation maximization (MLEM) are known to generate accurate image representation over analytical ...
[23], Little’s MCAR test was conducted in order to check if the data were missing completely at random. If nonsignificant, missing values were imputed using expectation maximization (EM) and imputed values were rounded to integers to reflect the answering format of the scale. All following ...
