Reconstruction of machine-made shapes from bitmap sketches
(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 ... -
Sketch2Pose : estimating a 3D character pose from a bitmap sketch
(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 ... -
Pricing and quality investments in a mixed brown-green product market
(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 ... -
Lexicographic optimization for the multi-container loading problem with open dimensions for a shoe manufacturer
(Springer, 2022-08-29)Motivated by a real-world application, we present a multi-container loading problem with 3-open dimensions. We formulate it as a biobjective mixed-integer nonlinear program with lexicographic objectives in order to reflect the decision maker’s ... -
A bilevel approach for the collaborative transportation planning problem
(Elsevier, 2020-12-15)The integration of the outbound and the inbound logistics of a company leads to a large transportation network, allowing to detect backhauling opportunities to increase the efficiency of the transportation. In collaborative networks, backhauling is ... -
Bilevel knapsack problems

Nash equilibria in the two-player kidney exchange game
(Springer, 2016-04-21)Kidney exchange programs have been set in several countries within national, regional or hospital frameworks, to increase the possibility of kidney patients being transplanted. For the case of hospital programs, it has been claimed that hospitals would ... -
Dynamic decision making in a mixed market under cooperation : towards sustainability
(Elsevier, 2021-08-21)Sustainability goals are becoming a priority in many societies. An important element in this context is the success of environmentally friendly products. Hence, we consider a manufacturer-retailer vertical supply chain model, managing a green product ... -
Singularity-free frame fields for line drawing vectorization
(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 ... -
Differential operators on sketches via alpha contours
(Association for Computing Machinery, 2023-08)A vector sketch is a popular and natural geometry representation depicting a 2D shape. When viewed from afar, the disconnected vector strokes of a sketch and the empty space around them visually merge into positive space and negative space, respectively. ...
