... study the problem of single-image zero-shot 3D shape reconstruction.
Recent works learn zero-shot shape reconstruction through generative modeling of 3D assets, but these models are computationally expensive at train and inference time.
... traditional approach to this problem is regression-based, where deterministic models are trained to directly regress the object shape.
Such regression methods possess much higher computational efficiency than generative methods.
... are regression-based approaches still competitive? To answer this, ... design a strong regression-based model, called ZeroShape, based on the converging findings in this field and a novel insight.
... ZeroShape ... achieves superior performance over state-of-the-art methods, but also demonstrates significantly higher computational and data efficiency.
