CONSTANT QUALITY CONTROL OF WYNER-ZIV FRAMES IN DCT DOMAIN DISTRIBUTED VIDEO CODING
Distributed video coding Constant quality control Greedy algorithm Adaptive uniform quantizer
2013/7/24
For most DCT domain distributed video coding systems, xed uniform quan-tizers are used to quantize all Wyner-Ziv (WZ) frames. However, it leads to uctuantvideo quality because the WZ frame quality is...
A New Text Detection Algorithm in Images/Video Frames
Text Detection Algorithm Images/Video Frames
2010/12/14
In this paper, we propose a new text detection algorithm for images/video frames in a coarse-to-fine framework. Firstly, in the coarse detection, multiscale wavelet energy feature is employed to locat...
Fast and robust text detection in images and video frames
Text detection Multiscale wavelet feature Feature combination SVM classification
2013/7/23
Text in images and video frames carries important information for visual content understanding and retrieval. In this paper, by using multiscale wavelet features, we propose a novel coarse-to-fine alg...
