“…They consider major labeling layout problems such as label layouts (flash or radial, internal or external), placement of external labels into empty space, minimization of line crossings, elimination of label overlapping etc. Floating Labels [10] uses some potential force fields to eliminate overlapping of labels. It also addresses frame coherency to minimize visual discontinuity.…”

The parallel processing of verbal elements like textual labels, annotations etc. with non-verbal i.e. visual elements, provides maximum integration of human mind. Textual labels and annotations aid in understanding medical data visualization. But it is a very challenging task to generate hand-made like illustration labels in an automated system. The paper presents a noble approach for dynamic external labeling of segmented 2D computer tomography (CT) slices. Various efficient algorithms are approached to solve labeling problems in modular form. The system emphasizes on the readability and clarity of labels while generating dynamic group labels in real time for 2D slices using external labeling layout.

“…We improved the cost map algorithm by Rosten et al [21] considering also the label overlapping and moving the labels towards the minimum cost direction. In our cost map we added the effect of a force field as suggested by Hartmann et al [22] to constraint labels inside the view window.…”

We present a novel approach, called tangible digital master (TaDiMa), based on a flexible access to Product Lifecycle Management (PLM) database using a tangible/graphical user interface and augmented reality. We developed and tested a technical drawing template with automatically embedded markers for augmentation. We embedded the Mozilla FireFox engine into our annotation system for the integration of web 2.0 applications in the AR environment. We also extended the concept of web feed to PLM for notification of technical contents. We implemented a dynamic labelling management with view-driven filtering and placement. We also present a tangible management for layers visualization and users access by marked tokens. We validated the TaDiMa approach in a selection of possible scenarios for different PLM applications. The main benefit of the TaDiMa system is the easy and low-cost integration in the product lifecycle process.

“…They also introduce hysteresis to minimize temporal discontinuity. [Hartmann et al 2004] model the problem using potential fields. Labels are positionned by diffusion of an energy, starting from the middle of the scene.…”

Figure 1: An example of dynamic labeling for a complex scene. See accompanying video for better demonstration. AbstractThis work presents a novel approach for dynamically rendering annotations attached to a 3D scene. We formulate the problem as a general optimization under constraints, accounting for certain desirable properties. To approximately solve the NP-hard optimization problem in real-time, we present a particular heuristic that greedily places labels while maintaining constraints. Typical greedy label placement algorithms do not pay particular attention to the order of placement and, as a result, suffer from the fundamental limitation that successive labels get progressively more difficult to place. We use algorithmic and mathematical tools that compensate for the drawback of typical greedy approaches. In addition, they are well suited for GPU implementation, because they are completely image based. As a result, we can place tens of labels in real-time, as demonstrated in this paper.
