The components of LightGuider: (a) a 3D modeling view to place and modify luminaires, augmented with (b) a provenance tree, depicting several sequential modeling steps and parallel modeling branches, integrating information on the quality of the individual solutions, and providing guidance by pre-simulating and suggesting possible next steps to improve the design. A film-strip-like visualization (c) of screenshots helps to depict the evolution up to the currently selected state. A quality view (d) informs about the fulfillment level of the illumination constraints that need to be met, using bullet charts. Changing the weights of these constraints (e), and therefore, the lighting designer’s focus, triggers an update of the provenance tree node visualizations (reflecting the weights of the constraints in the distribution of the treemap space). Moreover, the defined weights are also considered in the generation of new suggestions, which are tailored towards satisfying constraints with higher weights.

Stacked kernel processing times in Ordinary LE/TM, and stacked kernel overheads due to property computation in Early LE/TM and Late LE/TM measured on four image families (a)-(d), at 8192 × 8192 pixels. For each family member, represented by a point in the x-axes of the respective plot groups (a)-(d), kernel processing times and overheads were averaged over 100 executions. Analogous kernels in LE/TM are colored similarly. The vertical order of the colored stripes does not necessarily reflect the order of operations.

Left: single frame from 240Hz short-exposure video and a simulated long exposure at 30Hz by averaging 8 frames. Middle: Using the 240Hz input, our method enables mixing a long exposure in the periphery with a short exposure for the details on the pendulum. Via user annotations in the video, different shutter functions can be defined (top right). Annotations and shutter functions can be keyframed over time. Based on the annotations, our method defines an interpolated shutter function for each pixel (bottom right).

The valuables (magenta) have to be dragged to the dropzone (green circle). If the junk (brown) ends up in the dropzone the score decreases. The space snot (large green blob) is an obstacle in which ships and valuables can get stuck.

Left: In the first detector setup the sample is illuminated by collimated light. The scattered light is captured and coupled into a fiber cable by an achromatic lens. The fiber cable is connected to an Ocean Optics Spectrometer. — Right: In the second detector setup the achromatic lens is replaced by an integrating sphere from Thorlabs and the sample is illuminated by converged light.

LDA accuracy and rejection size per sample. (A) boxplot of the LDA accuracy distribution per sample, while using a rejection threshold (0 = no rejection). (B) Boxplot of the rejection percentage per sample while using a rejection threshold (0 means no rejection).

Three kinetic modules of pseudotime-dependent genes (n= 1,376) depicted in a log-variance-stabilized expression heat map, indicating gene-enriched biological processes. Genes confirmed by mass cytometry and flow cytometry are denoted by black labels, and genes involved in TCR signaling are denoted by gray labels. The dashed gray box indicates the coordinated expression profile of TNF, FASL and FYN. Euclidean distance values comparing gene expression profiles for each ordered pair of neighboring cells along the pseudotime trajectory are shown in the graph (right).
