Image Quality Assessment Using Spatial Frequency Component
Image Quality Assessment Spatial Frequency Component
2008/12/31
Image quality assessment (IQA) is a crucial technique in perceptual image/video coding, because it is not only a ruler for performance evaluation of coding algorithms but also a metric for ratio-disto...
EXTRACTION OF RAILROAD OBJECTS FROM VERY HIGH RESOLUTION HELICOPTER-BORNE LIDAR AND ORTHO-IMAGE DATA
LIDAR object extraction three-dimensional GIS integration
2008/11/16
LiDAR (Light Detection and Ranging) sensors and digital aerial camera systems using a slow and low flying aircraft provide a new
quality of data for a variety of promising large-scale applications. ...
MULTI IMAGE MATCHING OF STRAIGHT LINES WITH GEOMETRIC CONSTRAINTS
Matching, Straight Lines Correlation Plane Intersection
2008/11/16
Automatic multi image matching of linear features still remains to be a problem in both the photogrammetric and computer vision
communities. Changes in the illumination conditions, camera position, ...
Depth Image Segmentation for Improved Virtual View Image Quality in 3-DTV
Depth Image Segmentation Improved Virtual View Image Quality
2007/12/31
A rate-based switch fabric called smoothed buffer crossbar has been proposed in our recent work. It can provide 100% rate-guaranteed service with only a two-cell buffer at each
crosspoint, and can al...
REALISTIC FACIAL ANIMATION SYNTHESIS AND TRANSFER BASED ON FLEXIBLE EXPRESSION RATIO IMAGE
REALISTIC FACIAL ANIMATION SYNTHESIS TRANSFER FLEXIBLE EXPRESSION RATIO IMAGE
2007/12/31
Geometry-controlled image warping performs well in exhibiting shape variations but bad in exhibiting wrinkle such as fossette. Successfully applied in expression cloning,Expression Ratio Image(ERI) pr...
A Fast Approach for Natural Image Matting Using Structure Information
Natural Image Matting Structure Information
2007/12/31
Natural image matting plays an important role in image and video editing. It has been addressed hotly because it is inherently an under-constrained problem – we must estimate
both the foreground and ...

Image Matching by Multiscale Oriented Corner Correlation
Image Matching Multiscale Oriented Corner Correlation
2006/12/31
Abstract. In this paper we present a simple but effective method for matching two uncalibrated images. Feature points are firstly extracted in each image using a fast multiscale corner detector. Each ...
Image Matching by Normalized Cross-Correlation
Image Matching Normalized Cross-Correlation
2006/12/31
Correlation is widely used as an effective similarity measure in matching tasks. However, traditional correlation based matching methods are limited to the short baseline case. In
this paper we propo...
Effective and Efficient Object-based Image Retrieval Using Visual Phrases
Object-based Image Retrieval Visual Phrases
2006/12/31
In this paper, we draw an analogy between image retrieval and text retrieval and propose a visual phrase-based approach to retrieve images containing desired objects. The visual phrase is defined as a...
In the area of image retrieval, post-retrieval processing is often used to refine the retrieval results to better satisfy users’requirements. Previous methods mainly focus on presenting users with rel...
View Sequence Coding Using Warping-based Image Alignment for Multi-View Video
View Sequence Coding Image Alignment
2006/12/31
Multi-view video sequences are recorded by multiple cameras simultaneously. In view direction the images captured by different cameras in the same time instant form the view image sequences. The view ...
Improving the Image Retrieval Results via Topic Coverage Graph
Image retrieval re-rank topic coverage
2006/12/31
In the area of image retrieval, search engines are tender to retrieve images that are most relevant to the users’ queries. Nevertheless, in most cases,queries cannot be represented just by several que...
A Broadcast Model for Web Image Annotation
Web image annotation retrieval Broadcast Model
2006/12/31
Automatic annotation of Web image has great potential in improving the performance of web image retrieval. This paper presents a Broadcast Model (BM) for Web image annotation. In this model, pages are...
