[ACM Press SIGGRAPH Asia 2017 Posters - Bangkok, Thailand (2017.11.27-2017.11.30)] SIGGRAPH Asia 2017 Posters on - SA '17 - 4D computed tomography measurement for growing plant animation

摘要： Detailed observation of plant growth is essential for botanical analysis and realistic animation design. This study introduces spatial-temporal measurement techniques for a growing plant using X-ray Computed Tomography (CT). We scanned a target plant using CT over the course of couple of days with fixed time intervals to obtain four-dimensional (4D) volumetric images. We present a technique to segment the obtained 4D-CT images semi-automatically. We provide a 4D-CT measurement of budding bean sprouts to illustrate the feasibility of it.
