THE APPLICATION OF CONTENT-BASED INDEXING AND RETRIEVAL OF DIGITAL PICTURES AND RANGE IMAGES TO THE 3D VIRTUAL RECONSTRUCTION OF COMPLEX SITES AND ARCHITECTURES
Content-based indexing/retrieval model range images registration three-dimensional 3D
2015/10/8
The modelling of complex objects and sites involve the acquisition of a large number of texture maps and range images; each one of
them representing a particular viewing angle. These views must be c...
Phase Retrieval via Matrix Completion
Diffraction Fourier transform convex optimization trace-norm minimization
2015/6/17
This paper develops a novel framework for phase retrieval, a problem which arises in X-ray crystallography, diffraction imaging, astronomical imaging and many other applications. Our approach, called ...
Phase Retrieval from Coded Diffraction Patterns
Phase Retrieval Coded Diffraction Patterns
2015/6/17
This paper considers the question of recovering the phase of an object from intensity-only measurements, a problem which naturally appears in X-ray crystallography and related disciplines. We study a ...
Phase Retrieval via Wirtinger Flow:Theory and Algorithms
Phase Retrieval Wirtinger Flow Theory Algorithms
2015/6/17
We study the problem of recovering the phase from magnitude measurements; specifically, we wish to reconstruct a complex-valued signal x ∈ Cn about which we have phaseless samples of the form yr = ∣&#...
Hierarchical Optimization of Visual Vocabulary for Effective and Transferable Retrieval
Hierarchical Optimization Visual Vocabulary Effective
2009/12/31
Scalable image retrieval systems usually involve hierarchical quantization of local image descriptors, which produces a visual vocabulary for inverted indexing of images. Although hierarchical quantiz...
Large-Scale Cross-Media Retrieval of WikipediaMM Images with Textual
Large-Scale Cross-Media Retrieval WikipediaMM Images
2009/12/31
In this paper, we present our approaches for the WikipediaMM task at ImageCLEF 2008. We first experimented with a text-based image retrieval approach with query expansion, where the extension terms we...
PKU at ImageCLEF 2008: Experiments with Query Extension Techniques for Text-Base and Content-Based Image Retrieval
ImageCLEF 2008 Query Extension Techniques
2008/12/31
In this paper, we present our solutions for the WikipediaMM task at ImageCLEF 2008. The aim of this task is to investigate effective retrieval approaches in the context of a large-scale and heterogene...
Attention-Driven Action Retrieval with DTW-based 3D Descriptor Matching
Attention-Driven Action Retrieval DTW-based 3D Descriptor Matching
2008/12/31
From visual perception viewpoint, actions in videos can capture high-level semantics for video content understanding and retrieval.However, action-level video retrieval meets great challenges, due to ...
Cross-media manifold learning for image retrieval & annotation
Cross-media image retrieval
2008/12/31
Fusion of visual content with textual information is an effective way for both content-based and keyword-based image retrieval.However, the performance of visual & textual fusion is affected greatly b...
Place Retrieval with Graph-based Place-View Model
Place Retrieval Graph-based Place-View Model
2008/12/31
Places in movies and sitcoms could indicate higher-level semantic cues about the story scenarios and actor relations. This paper presents a novel unsupervised framework for efficient place retrieval i...
DRM: Dynamic Region Matching for Image Retrieval Using Probabilistic Fuzzy Matching and Boosting Feature Selection
Dynamic Region Matching Image Retrieval Probabilistic Fuzzy Matching
2008/12/31
This paper considers the semantic gap in content-based image retrieval from two aspects: (1)
irrelevant visual contents (e.g. background) scatter the mapping from image to human perception; (2) unsup...
Previous web image re-ranking approaches usually construct similarity measure on image level. Considering the diversity of large scale web image database, these approaches ignore the
difference of im...
