“…It is useful to quantitatively characterize the internal structures of flame. In 2003, Hasinoff and Kutulakos [3] presented a photo-consistent reconstruction method which reduces fire reconstruction to the convex combination of sheet-like density fields. It is easy to implement two-view reconstruction, but multi-view (more than two views) reconstruction has very high computational complexity.…”

“…However, they also have two significant problems. On the one hand, twoview reconstruction methods, such as multiplication and flame sheet generation [3] are easy to implement but yield poor visual effects. Multi-view (>2) reconstruction methods generate 3D modeling accurately but are high timeconsuming due to computational complexity.…”

“…Thus, it is preferable to develop a reconstruction algorithm with a simple system setup, which decreases the setup time making the process more cost efficient and produces visually plausible results. On the other hand, most of the existing color-imagebased methods [3][4][5] reconstruct three density fields from RGB intensities according to the order of their appearance. These methods suffer from color distortion due to the high correlation of RGB intensities.…”

The reconstruction of flame from the captured images is a difficult and computationally expensive problem. Reconstruction from color images will keep the colorful appearance, as is beneficial for visually realistic flame modeling. Most of existing color-image-based methods rebuild three density fields from RGB intensities; however, these methods suffer from the color distortion problem due to the high correlation of RGB intensities. A novel method for 3D flame reconstruction using color temperature is presented in this paper. Color-temperature mapping is calculated to avoid color distortion; this method maps the RGB intensities into the color temperature and its joint intensity. We improve the multiplication reconstruction with visual hull restriction so that the energy distribution is more reasonable, which allows avoidance of the impossible zones. Experimental results indicate that our approach is efficient in the visually plausible 3D flame generation and produces better color restorations.

“…Results were mainly shown for synthetic problems, but even for those, the quality of interpolated views was limited. Similarly, the iterative voxel reconstruction approach presented in [16] gave results unsuitable for view synthesis, whereas [17] is more appropriate for volumetric scenes that are semi-transparent everywhere. Mixed pixels for stereo §4.…”

“…There has been some work done on estimating transparency from stereo data in general terms [6,16,17]. In [6], transparency was estimated in a volumetric fashion along with depth, using a plane-sweep algorithm, generalized to a four-dimensional xydα search space.…”

In the last few years, new view synthesis has emerged as an important application of 3D stereo reconstruction. While the quality of stereo has improved, it is still imperfect, and a unique depth is typically assigned to every pixel. This is problematic at object boundaries, where the pixel colors are mixtures of foreground and background colors. Interpolating views without explicitly accounting for this effect results in objects with a "cut-out" appearance.To produce seamless view interpolation, we propose a method called boundary matting, which represents each occlusion boundary as a 3D curve. We show how this method exploits multiple views to perform fully automatic alpha matting and to simultaneously refine stereo depths at the boundaries. The key to our approach is the 3D representation of occlusion boundaries estimated to sub-pixel accuracy. Starting from an initial estimate derived from stereo, we optimize the curve parameters and the foreground colors near the boundaries. Our objective function maximizes consistency with the input images, favors boundaries aligned with strong edges, and damps large perturbations of the curves. Experimental results suggest that this method enables high-quality view synthesis with reduced matting artifacts.

We introduce novel approaches of intuitive and easy‐to‐use realistic fire animation, starting from real‐life fire by image‐based techniques and statistical analysis. The results can be utilized as a pre‐rendered sequence of images in video games, motion graphics, and cinematic visual effects. Instead of physics‐based simulation, we employ an example‐based principal component analysis and introduce “EigenFires.” We visualize the main features of various fire samples to analyze their tracks and synthesize a new fire by combining various fire samples, recorded with high frame rates, in order to edit given sequences of fire animations. For this purpose, we present how to recognize similarity of the shapes of fire in order to change the pattern from one style of fire to another distinct style of fire procedurally. Our techniques require very little parameter tuning, compared with conventional physically based fire synthesis, video textures, and dynamic textures. A similar level of visually pleasing compressed fire is also easily produced by using principal component analysis techniques. Copyright © 2013 John Wiley & Sons, Ltd.
