The application of multi-modality medical image fusion based method to cerebral infarctionSpringer Science and Business Media LLC - Tập 2017 - Trang 1-16 - 2017
Yin Dai, Zixia Zhou, Lu Xu
A multi-modality image fusion can process images of certain organs or issues which were collected from diverse medical imaging equipment. The fusion can extract complementary information and integrate into images with more comprehensive information. The multi-modality image fusion can provide image that was combined with anatomical and physiological information for doctors and bring convenience fo...... hiện toàn bộ
No-reference image blur assessment using multiscale gradientSpringer Science and Business Media LLC - Tập 2011 - Trang 1-11 - 2011
Ming-Jun Chen, Alan C Bovik
The increasing number of demanding consumer video applications, as exemplified by cell phone and other low-cost digital cameras, has boosted interest in no-reference objective image and video quality assessment (QA) algorithms. In this paper, we focus on no-reference image and video blur assessment. We consider natural scenes statistics models combined with multi-resolution decomposition methods t...... hiện toàn bộ
Research on the effect of image size on real-time performance of robot vision positioningSpringer Science and Business Media LLC - Tập 2018 - Trang 1-11 - 2018
Desheng Lyu, Heyang Xia, Chen Wang
In order to improve the real-time performance of visual positioning of the indoor mobile robot, the researchers found that the shape and size of the positioned image have a great influence on the real-time performance of the positioning calculation. In order to verify the conclusion and find the appropriate image shape and size to meet the robot’s visual positioning requirements, this paper adopts...... hiện toàn bộ
Parity Bit Replenishment for JPEG 2000-Based Video StreamingSpringer Science and Business Media LLC - Tập 2009 - Trang 1-18 - 2009
Christophe De Vleeschouwer, François-Olivier Devaux
This paper envisions coding with side information to design a highly scalable video codec. To achieve fine-grained scalability in terms of resolution, quality, and spatial access as well as temporal access to individual frames, the JPEG 2000 coding algorithm has been considered as the reference algorithm to encode INTRA information, and coding with side information has been envisioned to refresh t...... hiện toàn bộ
Performance analysis of massively parallel embedded hardware architectures for retinal image processingSpringer Science and Business Media LLC - Tập 2011 - Trang 1-17 - 2011
Alejandro Nieto, Victor Brea, David L Vilariño, Roberto R Osorio
This paper examines the implementation of a retinal vessel tree extraction technique on different hardware platforms and architectures. Retinal vessel tree extraction is a representative application of those found in the domain of medical image processing. The low signal-to-noise ratio of the images leads to a large amount of low-level tasks in order to meet the accuracy requirements. In some appl...... hiện toàn bộ
Image analysis using new set of separable two-dimensional discrete orthogonal moments based on Racah polynomialsSpringer Science and Business Media LLC - Tập 2017 - Trang 1-17 - 2017
Imad Batioua, Rachid Benouini, Khalid Zenkouar, Hakim El Fadili
In this paper, we propose three new separable two-dimensional discrete orthogonal moments baptized: RTM (Racah-Tchebichef moments), RKM (Racah-Krawtchouk moments), and RdHM (Racah-dual Hahn moments). We present a comparative study between our proposed separable two-dimensional discrete orthogonal moments and the classical ones, in terms of gray-level image reconstruction accuracy, including noisy ...... hiện toàn bộ
Adding spatial distribution clue to aggregated vector in image retrievalSpringer Science and Business Media LLC - Tập 2018 - Trang 1-14 - 2018
Pingping Liu, Zhuang Miao, Huili Guo, Yeran Wang, Ni Ai
This study proposes a novel algorithm that enhances the distinctiveness of the traditional vector of locally aggregated descriptors (VLAD) using spatial distribution clue of local features. The algorithm introduces a new method to compute the spatial distribution entropy (SDE) of clusters. Unlike conventional methods, this algorithm considers the distribution of full spatial information provided b...... hiện toàn bộ
Real-time CUDA-based stereo matching using Cyclops2 algorithmSpringer Science and Business Media LLC - Tập 2018 - Trang 1-15 - 2018
Arnas Ivanavičius, Henrikas Simonavičius, Julius Gelšvartas, Andrius Lauraitis, Rytis Maskeliūnas, Piotras Cimmperman, Paulius Serafinavičius
This paper presents a novel stereo matching algorithm Cyclops2. The algorithm produces a disparity image, provided two rectified grayscale images. The matching is based on the concept of minimising a weight function calculated using the absolute difference of pixel intensities. We present three simple and easily parallelizable weight functions. Each presented function gives a different trade-off b...... hiện toàn bộ
