A Point Set Generation Network for 3D Object Reconstruction from a Single Image (1612.00603v2)

Abstract: Generation of 3D data by deep neural network has been attracting increasing attention in the research community. The majority of extant works resort to regular representations such as volumetric grids or collection of images; however, these representations obscure the natural invariance of 3D shapes under geometric transformations and also suffer from a number of other issues. In this paper we address the problem of 3D reconstruction from a single image, generating a straight-forward form of output -- point cloud coordinates. Along with this problem arises a unique and interesting issue, that the groundtruth shape for an input image may be ambiguous. Driven by this unorthodox output form and the inherent ambiguity in groundtruth, we design architecture, loss function and learning paradigm that are novel and effective. Our final solution is a conditional shape sampler, capable of predicting multiple plausible 3D point clouds from an input image. In experiments not only can our system outperform state-of-the-art methods on single image based 3d reconstruction benchmarks; but it also shows a strong performance for 3d shape completion and promising ability in making multiple plausible predictions.

• The paper outlines comprehensive formatting standards for CVPR submissions, specifying layout, font styles, and section numbering.
• It mandates a blind review process by requiring anonymized self-references and a standardized structure to ensure impartial evaluations.
• It emphasizes practical tools like a printed ruler and strict page limits, promoting clarity and consistency in academic manuscripts.

Overview of "LaTeX Author Guidelines for CVPR Proceedings"

The document titled "LaTeX Author Guidelines for CVPR Proceedings" serves as a comprehensive style guide for researchers preparing manuscripts for submission to the CVPR conference. This paper elucidates various formatting and style requirements, ensuring that submitted papers adhere to a consistent and professional standard.

Key Sections and Recommendations

Abstract

The Abstract is to be formatted in fully justified, italicized text. It must appear at the top of the left-hand column, immediately below the author and affiliation information. The term "Abstract" should be centered and bold in 12-point Times font.

Introduction and Language

The Introduction specifies that all manuscripts must be in English, reinforcing the importance of clear and accessible academic communication within the global research community.

Dual Submission and Paper Length

The guidelines caution against dual submissions, directing authors to the CVPR-specific policy on the issue. The allowable length for papers is strictly eight pages, excluding references, which are unlimited in length. Overlength papers will be rejected without review, highlighting the conference’s commitment to concise and focused research dissemination.

The Ruler and Mathematical Notation

A notable feature is the inclusion of a printed ruler along the side of the document, which aids reviewers in referencing specific lines. This ruler is to be removed in the final camera-ready version. The document also mandates the numbering of all sections and equations, facilitating precise reference by future readers.

Blind Review

For the Blind Review process, authors must avoid self-identification and must refer to their own work in the third person. This practice ensures an impartial review process by masking the authors' identities.

Formatting Details

The document provides meticulous instructions on formatting:

• Two-Column Format: All text should be formatted in two columns with specific dimensions for margins and spacing.
• Title and Author Information: The main title should be in 14-point bold Times font, centered, with author names and affiliations in 12-point non-bold Times font.
• Main Text: Should be in 10-point Times font, single-spaced, fully justified. Paragraphs are indented by 1 pica.
• Headings: Hierarchical headings are specified (first-order, second-order, and third-order), with specific styles for each.

Figures, references, and tables have detailed formatting rules, ensuring consistency in presentation and citation style.

Practical Implications

For practitioners and researchers submitting to CVPR, adherence to these guidelines is crucial. The structured and uniform presentation of research facilitates easier comprehension, comparison, and evaluation during the review process. Importantly, it ensures that all submissions meet the high standards expected by CVPR, reflecting the quality and rigor of the research community.

Speculation on Future Developments

While the guidelines are specific to CVPR, similar principles are likely to be adopted by other top-tier conferences as open-access and digital archiving become more prevalent. The approach to standardized formatting, anonymized reviews, and strict length limitations not only align with current best practices but also anticipate future trends in academic publishing standards.

Conclusion

The "LaTeX Author Guidelines for CVPR Proceedings" is an essential document for researchers aiming to contribute to CVPR. It encapsulates the expectations for manuscript preparation, promoting clarity, uniformity, and integrity in academic publication. As the landscape of AI and computer vision research evolves, these guidelines will continue to play a pivotal role in maintaining the high standards of scholarly communication at CVPR.
