  • Pricing and quality investments in a mixed brown-green product market 

    Mukherjee, Arka; Carvalho, Margarida (Springer, 2020-09-22)
    Sustainable Supply Chain Management (SSCM) has assumed a position of prominence for academics and industry over the last two decades. The sustainability literature shows that typically manufacturers aim to optimize their pricing and greening level ...

  • Probe-level linear model fitting and mixture modeling results in high accuracy detection of differential gene expression 

    Lemieux, Sébastien (2006)
    BACKGROUND:The identification of differentially expressed genes (DEGs) from Affymetrix GeneChips arrays is currently done by first computing expression levels from the low-level probe intensities, then deriving significance by comparing these expression ...

  • Reconstruction of machine-made shapes from bitmap sketches 

    Puhachov, Ivan; Martens, Cedric; Kry, Paul G.; Bessmeltsev, Mikhail (Association for computing machinery, 2023-12)
    We propose a method of reconstructing 3D machine-made shapes from bitmap sketches by separating an input image into individual patches and jointly optimizing their geometry. We rely on two main observations: (1) human observers interpret sketches ...

  • Singularity-free frame fields for line drawing vectorization 

    Guțan, Olga; Hegde, Shreya; Jimenez Berumen, Erick; Bessmeltsev, Mikhail; Chien, Edward (Wiley, 2023-07-19)
    State-of-the-art methods for line drawing vectorization rely on generated frame fields for robust direction disambiguation, with each of the two axes aligning to different intersecting curve tangents around junctions. However, a common source of ...

  • Sketch2Pose : estimating a 3D character pose from a bitmap sketch 

    Brodt, Kirill; Bessmeltsev, Mikhail (Association for computing machinery, 2022-07-22)
    Artists frequently capture character poses via raster sketches, then use these drawings as a reference while posing a 3D character in a specialized 3D software --- a time-consuming process, requiring specialized 3D training and mental effort. We tackle ...
