The presented book the authors offer here is not kind of usual book, but the book that it is proffer is the soft file of the book, which will precisely be profitable.
Adaptive Bilateral Filter for Sharpness Enhancement and Noise Removal
- Buyue Zhang, J. Allebach
- Computer ScienceIEEE Transactions on Image Processing
- 12 November 2007
The adaptive bilateral filter (ABF) sharpens an image by increasing the slope of the edges without producing overshoot or undershoot, and is an approach to sharpness enhancement that is fundamentally different from the unsharp mask (USM).
Zooming Slow-Mo: Fast and Accurate One-Stage Space-Time Video Super-Resolution
- Xiaoyu Xiang, Yapeng Tian, Yulun Zhang, Y. Fu, J. Allebach, Chenliang Xu
- Computer ScienceComputer Vision and Pattern Recognition
- 26 February 2020
A one-stage space-time video super-resolution framework is proposed, which directly synthesizes an HR slow-motion video from an LFR, LR video and proposes a deformable ConvLSTM to align and aggregate temporal information simultaneously for better leveraging global temporal contexts.
Edge-directed interpolation
- J. Allebach, P. Wong
- Computer ScienceProceedings of IEEE international conference on…
- 16 September 1996
A new method for digitally interpolating images to higher resolution based on bilinear interpolation modified to prevent interpolation across edges, as determined from the estimated high resolution edge map is presented.
Printer identification based on graylevel co-occurrence features for security and forensic applications
- A. Mikkilineni, Pei-Ju Chiang, G. N. Ali, G. Chiu, J. Allebach, E. Delp
- Computer ScienceIS&T/SPIE Electronic Imaging
- 21 March 2005
The use of image texture analysis to identify the printer used to print a document is described and a set of features that can be used to provide forensic information about a document are described.
Impact of HVS models on model-based halftoning
- Sang Ho Kim, J. Allebach
- Computer ScienceIS&T/SPIE Electronic Imaging
- 21 December 2000
A dual-metric DBS algorithm is developed that effectively provides a tone-dependent HVS model without a large increase in computational complexity.
Model-based halftoning using direct binary search
- M. Analoui, J. Allebach
- Computer ScienceElectronic imaging
- 27 August 1992
A new method to generate halftone images which are visually optimized for the display device by recursively computing the change in perceived mean-squared error due to a change in the value of a binary pixel, and achieves a substantial reduction in computational complexity.
Digital color halftoning
- F. A. Baqai, Je-Ho Lee, A. Agar, J. Allebach
- Computer ScienceIEEE Signal Processing Magazine
- 21 March 2005
Digital color halftoning algorithms can be placed in one of three categories: 1) point processes (screening or dithering), 2) neighborhood algorithms (error diffusion), and 3) iterative methods.
Optimal image scaling using pixel classification
- C. B. Atkins, C. Bouman, J. Allebach
- Environmental ScienceProceedings International Conference on Image…
- 7 October 2001
A simple derivation is presented to show that RS generates the minimum mean-squared error (MMSE) estimate of the high- resolution image, given the low-resolution image.
New results on reconstruction of continuous-tone from halftone
- M. Analoui, J. Allebach
- MathematicsIEEE International Conference on Acoustics…
- 23 March 1992
Two iterative methods are used to reconstruct a continuous-tone image from its halftone: successive approximation and projection onto convex sets and a constraint on the bandwidth of the reconstructed image.
