Adaptive Image Deblurring via Tanner Graph Representation and Belief Propagation
Adaptive Representation Belief Propagation
2013/7/24
Image deblurring aims to counteract the effect of point spread function (PSF) inimperfect image formation system. Conventional solutions include frequency-domainapproaches (e.g. Wiener filtering...
Adaptive Discriminant Analysis for face recognition from Single Sample per Person
Adaptive Discriminant Single Sample
2013/7/24
Discriminant analysis, especially Fisherface and its numerous variants, have achieved great success in face recognition. However, these methods fail to work for face recognition from Single Sample per...
Adaptive Moving Cast Shadow Detection
Shadow Detection Ratio Edge Ratio Brightness Video Surveillance.
2013/7/24
Moving object detection is an important task in real-time video surveillance. However, in real scenario, moving cast shadows associated with moving objects may also be detected, making moving cast s...

Line detection Hough Transform Tunnel Detection Random sampling Subsurface shape detection
2011/3/22
This paper examines the detection of parameterized shapes in multidimensional noisy grayscale images. A novel shape detection algorithm utilizing random sample theory is presented. Although the method...
Adaptive Wiener-turbo systems with JPEG & bit plane compressions in image transmission
Color and bit plane slicing fading channels JPEG image compression image transmission turbo coding
2011/3/22
In recent years, for transmission of 2D colored images over the fading channels, a new scheme has been denoted as ``adaptive Wiener-turbo systems with JPEG & bit plane compressions'' (AW-TSwJBC).
Block Adaptive Super Resolution Video Coding
Super-resolution interpolation rate-distortion cost
2013/7/16
Super resolution technique was first proposed for enhancing the image resolution, and then it was expanded to video sequence for obtaining a higher resolution video from low resolution input. Recently...
Extracting surface orientation and surface depth from one or more images is one of the classic problems in computer vision. Shape-from-shading (SFS) deals with the recovery of 3-D shape from a single ...

Side information interpolation distributed video coding equivalent kernel spatio-temporal local adaptive learning fusion
2013/7/16
Motivated by theoretical analysis of the curve fitting problem based on equivalent kernel, in this paper we propose a local adaptive learning and fusion model for side information interpolation in dis...
Kalman Filter Based Adaptive Reduction of Motion Artifact from Photoplethysmographic Signal
Kalman filter Motion artifact PPG Photoplethysmography
2010/2/2
Artifact free photoplethysmographic (PPG) signals are
necessary for non-invasive estimation of oxygen saturation (SpO2) in
arterial blood. Movement of a patient corrupts the PPGs with motion
artifa...
Scalable Wyner-Ziv Video Coding with Adaptive Bit-Plane Representation
Distributed video coding Wyner-Ziv coding bit-plane representation optimal quantization
2013/7/17
Scalable Wyner-Ziv video coding is desirable, especially for mobile devices with limited computational resources and bandwidth. However, the conventional bit-plane representation used in hybrid video ...
Adaptive rate control for H.264
