The Visualization & Visual Analytics research theme focuses on algorithms and mathematical models to present, transform and convert complex scientific multi-{modal, scale, variate} data into an efficient and effective visual representation that humans can rapidly and efficiently understand, analyze, and comprehend.

In Visualization (Vis), our group has focused on the area of illustrative visualization, based on principles from traditional scientific illustration to emphasize specific features, to expose subtle attributes, to omit extraneous information, among other visual communication goals.

To date, Illustrative visualization projects in our group are organized into four categories:

  1. Cutaway and Exploded view diagrams of 3D reservoir simulation grids (de Carvalho et al. '16, Martins Filho et al. ['12, '15]);
  2. Illustrative layering on surfaces using decals for multivariate data visualization with demonstration examples in geoscience & petroleum engineering (Rocha et al. ['17a, '18 (a, b)]), and oceanography (Rocha et al. '17b);

  3. Contextual close-up views of clinical volumetric data (Costa Sousa et al. '05b, Ebert et al. '05, Taerum et al. '06) and fundamental research of multi-resolution filters with demonstration examples of image-based focus+context (Hasan et al. '15, from RT-4: M&S). The research of Taerum et al. '06 resulted in a patent US7893940 B2 and technology transfer to a multi-platform, cloud-based visualization system. This system is in use by researchers and medical professionals in industry and academia worldwide (ResolutionMD® & PureWeb® from Calgary Scientific Inc.);

  4. Visibility compositing and masking for 3D models and medical data (Bruckner et al. '10);

In Visual Analytics (VA), our group has focused on interactive visual representations and analytical reasoning models to extract, cluster, and compute similarities and correlations between samples from high-dimensional data and large parameter spaces.

To date, visual analytics projects in our group are organized into three categories:

  1. Mathematical models and algorithms for multi-dimensional data projection (Amorim E et al. ['12a, '14, '15]) and information theory-based analytics (Sahaf et al. ['16, '17(a, b), '18]).

  2. Data from numerical simulations, including six sub-categories: (2.1) Geological well-test visual steering (Hamdi et al. '15d); (2.2) Reservoir simulation post-processing analysis (Amorim E et al. '12b, Somanath et al. ['12, '14]); (2.3) History matching and reservoir optimization (Hajizadeh et al. '12, Hamdi et al. '15d); (2.4) Multi-parameter sensitivity analysis (Karami Moghadam et al. ['12, '18]); (2.5) Geostatistical modeling for flow simulation studies (Sahaf et al. ['16, '17b, '18]); and (2.6) Reservoir connectivity analysis (Cabral R Mota et al. '16(a, c), with '16a also from RT-5: HDCI);

  3. Acquired & processed data, including five sub-categories: (3.1) Micro-seismic event monitoring (Mostafa et al. ['12, '13 (a, b)]); (3.2) Microfabrics from petrological databases (Cevolani et al. '13); (3.3) Oil & gas pipeline operations (Sahaf et al. '17a, awarded the first place in the 2015 IBM Canada / U. of Calgary Advanced Energy Analytics for the Energy Industry Competition); (3.4) Criminal investigation data (Bhaskar et al. '14), in the IEEE Visual Analytics Science and Technology (VAST) 2014 Mini Challenge 1; and (3.5) Facial feature expressions for 3D content creation (Amorim E et al. '15).
