Camera Animation for Immersive Light Field Imaging

Abstract

Among novel capture and visualization technologies, light field has made significant progress in the current decade, bringing closer its emergence in everyday use cases. Unlike many other forms of 3D displays and devices, light field visualization does not depend on any viewing equipment. Regarding its potential use cases, light field is applicable to both cinematic and interactive contents. Such contents often rely on camera animation, which is a frequent tool for the creation and presentation of 2D contents. However, while common 3D camera animation is often rather straightforward, light field visualization has certain constraints that must be considered before implementing any variation of such techniques. In this paper, we introduce our work on camera animation for light field visualization. Different types of conventional camera animation were applied to light field contents, which produced an interactive simulation. The simulation was visualized and assessed on a real light field display, the results of which are presented and discussed in this paper. Additionally, we tested different forms of realistic physical camera motion in our study, and based on our findings, we propose multiple metrics for the quality evaluation of light field visualization in the investigated context and for the assessment of plausibility.

Light Field Visualization for Training and Education: A Review

“…This challenge may affect the rendering of complex structures that needs to be scaled up considerably to view it more clearly (e.g., molecules). In previous works [162,163], we have acknowledged that using a first-person camera for LFDs result in deteriorated outputs. The same can be thought of when scaling objects.…”

How I Met Your V2X Sensor Data: Analysis of Projection-Based Light Field Visualization for Vehicle-to-Everything Communication Protocols and Use Cases

“…Recent works on light field technology cover the topics of angular enhancement [ 100 , 101 , 102 ] (which aims to achieve super-resolution), image enhancement [ 103 , 104 , 105 ] (which is also often named super-resolution, and thus, the terminology of the other one is becoming “angular super-resolution”), saliency detection [ 106 , 107 , 108 ], light field rendering [ 109 , 110 , 111 ] and reconstruction [ 112 , 113 , 114 ], microscopy [ 115 , 116 , 117 ], camera animation [ 118 ], video streaming [ 119 ], objective quality assessment [ 120 , 121 ], perceived quality [ 94 , 122 ], and many more. Every single experiment that studies the projection-based light field visualization with the involvement of human individuals is summarized in a recent work [ 123 ], along with a thorough analysis of future research efforts, and an up-to-date survey [ 124 ] investigates the associated methods.…”

KULF-TT53: A Display-Specific Turntable-Based Light Field Dataset for Subjective Quality Assessment

“…Darukumalli et al [48] conducted a study on the HoloVizio C80 light field cinema system to assess how the zoom level impacts the subjective quality of light field contents. Guindy et al [49] created light field contents for different types of camera animations and visualized them on the same light field display to assess feasibility. Tamboli et al [12] introduced a light field dataset-assisted by a turntable-of real-world objects, capturing one view per degree for a complete 360 degrees.…”
