Area of Science:

• Computer Vision
• Geometric Modeling
• Machine Learning

Background:

• Multimodel fitting commonly uses energy minimization with fitting error and regularization terms.
• Existing methods often struggle with unknown data error distributions and outliers, leading to biased estimations.

Purpose of the Study:

• To introduce a novel energy function for multimodel fitting that incorporates high-level geometric priors.
• To exploit interactions between geometric models for preferred configurations in applications like surface fitting.

Main Methods:

• Developed a new energy function integrating geometric priors that consider inter-model relationships.
• Utilized the expansion move method for efficient minimization of the proposed energy function.
• Evaluated performance on real-world computer vision datasets.

Main Results:

• The proposed method effectively handles unknown data error distributions and outliers.
• Experimental results demonstrate superior performance compared to state-of-the-art methods.
• Achieved improved accuracy without a significant increase in computational cost.

Conclusions:

• Incorporating high-level geometric priors into energy minimization offers significant advantages for multimodel fitting.
• The novel energy function provides a robust and efficient solution for computer vision applications.
• This approach enhances the reliability and accuracy of geometric model fitting in challenging scenarios.
