Curvelets–A Surprisingly Effective Nonadaptive Representation For Objects with Edges
Curvelets Nonadaptive Representation Objects with Edges
2015/6/17
It is widely believed that to efficiently represent an otherwise smooth object with discontinuities along edges, one must use an adaptive representation that in some sense ‘tracks’ the shape of the di...
A NEW EFFECTIVE WAY ON VEGETATION MORNITORING USING MULTI-SPECTRAL CANOPY LIDAR
Remote Sensing Vegetation Monitoring Global-Environmental LIDAR Spectral
2012/7/20
Airborne Laser Scanning (ALS) has been a well-established tool for the measurement of surface topography as well as for the estimation of biophysical canopy variables, such as tree height and vegetati...
Camera motion analysis (CMA) is very useful for many video content analysis tasks, but few works competently handle the videos with significant camera or object motion. In
this paper, we present an e...
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...
Text in images and videos is a significant cue for visual content understanding and retrieval. In this paper, we present a fast and effective approach to locate text lines
even under complex backgrou...
Fast and Effective Interpolation Using Median Filter
Effective Interpolation Median Filter
2008/12/31
This paper proposes a fast and effective image interpolation algorithm
using median filter. The interpolation algorithm is composed of two steps.
First, a non-linear iterative procedure is utilized ...
Effective algorithms for fast transcoding of AVS to H.264/AVC in the spatial
AVS H.264/AVC Transcoding Mode mapping
2007/12/31
This paper proposes a transcoding scheme from AVS to H.264/AVC. As highcompression
video coding standards, H.264/AVC jointly developed by MPEG and ITU and
AVS developed by the Audio Video Coding Sta...
AN EFFECTIVE LOCAL INVARIANT DESCRIPTOR COMBINING LUMINANCE AND COLOR INFORMATION
EFFECTIVE LOCAL INVARIANT DESCRIPTOR COMBINING LUMINANCE COLOR INFORMATION
2007/12/31
Extraction of stable local invariant features is very important in many computer vision applications, such as image matching, object recognition and image retrieval. Most
existing local invariant fea...
An effective mode decision scheme in macroblock-based PFGS
decision scheme macroblock-based PFGS
2006/12/31
The Progressive Fine Granularity Scalable (PFGS) coding is a promising technique for streaming video applications. The macroblock-based PFGS coding proposes several INTER
modes for the enhancement ma...
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...
AN EFFECTIVE SCORING METHOD FOR SPEAKING SKILL EVALUATION SYSTEM
Speaking Skill Evaluation CDCPM CAP Automatic Pronunciation Scoring
1999/9/28
The Speaking Skill Evaluation (SSE) technologies are derived from speech recognition technologies and are used for language learning and instructing. In this paper, an effective automatic pronunciatio...
