| <!-- Provide a quick summary of the dataset. --> |
|
|
| The SHREC 2021 Track on Quantifying Shape Complexity aimed to provide a benchmark for the quantification of 3D shape complexity. Shape complexity is an ill-defined concept. Hence, the concept is explored complexity multiple tasks and data collections. Due to the relative nature of complexity, a linear order may not make sense. There may be multiple aspects of complexity that can be measured. |
|
|
| - In the first collection, we consider synthetically acquired noisy cubes and spheres. |
| - The second collection consists of abstract shapes and is made up of two subcollections each composed of 25 shapes. |
| - The third part consists of the categorized shapes of the Princeton Segmentation Benchmark (Chen et al., "A Benchmark for 3D Mesh Segmentation", TOG, 28.3, 2009). |
| Collection 3 can be accessed at [here](https://segeval.cs.princeton.edu). |
|
|
|
|
| Each of these collections can be considered as seeking a different aspect of shape complexity. |
