IEEE international Workshop on Imaging systems and Techniques (IST)

作者： Jun Ke Ping Wei Xin Zhang Edmund Y. Lam Key Laboratory of Photo-electronic Imaging Technology and System Beijing Institute of Technology Beijing China Chinese Academy of Sciences Institute of Automation Beijing China Electrical and Electronic Engineering Department University of Hong Kong Pokfulam Hong Kong China

In this paper, block-based compressive low-light-level imaging (BCL-imaging) is studied. To obtain larger measurement SNR (signal to noise ratio), instead of object pixels, linear combinations of pixels, referred to as features, are collected. PCA and Hadamard features are studied. Measurement SNR and reconstruction error are analyzed to quantify BCL-imaging performance. Compared with conventional imaging, BCL-imaging presents better reconstruction quality. Between PCA and Hadamard projections, PCA has smaller reconstruction error. However, after sorting the projection vectors using measurement SNR, Hadamard can obtain similarly performance as PCA. Biased vector and dual-measurements are studied with experimental results for the implementation of both projections in the end of this paper.

international conference on Industrial and Information systems, ICIIS

作者： Teerath Das Bishwajeet Pandey Mohamed Hashim Minver Tanesh Kumar Department of Computer Science South Asian University Delhi India

In this paper, green image ALU is designed in Xilinx ISE 14.6 using LVDCI(Low Voltage Digitally Control Impedance) and LVDCI_DV2(Half Impedance Version of LVDCI) I/O standard in 40nm Virtex-6 FPGA. By using LVDCI technology we achieve energy efficiency with respect to low voltage impedance. In this whole work, we are using three different classes of LVDCI and LVDCI_DV2 and observe that when image ALU operates at 1THz device operating frequency with LVDCI_15 and LVDCI_DV2_15 I/O Standard, there is 52.87% and 65.67% reduction in IO power than LVDCI_25 and LVDCI_DV2_25 Standard respectively. In image ALU, there are 16 different operations (logical and arithmetic). There is no any change in Clock power, Leakage power and signal power of image ALU using LVDCI and LVDCI_DV2 I/O Standard.

The video shot boundary detection is an area, where many techniques and methods have been suggested and have claimed to perform consistently on the videos like television broadcasting of different sports events, talk shows & news telecast. The movies contain a large amount of visual information varying in arbitrary manner; it requires a highly vigorous procedure for automatic shot boundary detection. The main goal of this research is to develop an adaptive & robust algorithm for segmentation & classification of movie videos. In this paper, we described a novel approach for shot boundary detection which is totally adaptive & changes the threshold value as per the information change. We have defined the novel feature which can uniquely define color as well as edge & frequency details of a frame. It is able to detect not only abrupt transitions like hard cuts but also special effects like wipes, fades, and dissolves as well in different movies.

IEEE international conference on Electronics, Circuits and systems (ICECS)

作者： Alavi Kunhu Hussain Al-Ahmad Electrical and Computer Engineering Department Technology and Research UAE

This paper deals with a blind multi watermarking algorithm which embeds robust ownership watermark and fragile authentication information into satellite images to protect the copyright ownership and integrity of the images. The robust watermark is embedded first in the discrete wavelet transform (DWT) and the second hash authentication code is embedded in the spatial domain. The new technique offers high peak signal to noise ratio (PSNR) and similarity structure index measure (SSIM) values. The technique was successfully tested on a variety of satellite images. The fragile watermark is sensitive to any slight tampering and can locate the area of the editing. The robust watermark survived many intentional and non intentional attacks.

The computational load is prohibitive in 3D sonar systems for real-time image generation. In the literature, an efficient frequency beamforming method based on the distributed and parallel subarray (DPS) has been introduced for planar arrays working in the far field. This paper extends the DPS beamforming algorithm to process the signals acquired from a scene in the near field. The alogrithm divides the full populated transducer array into two stage distributed subarrays. It performs parallel beamforming on the first-stage subarrays and applies the approximation for time delays in the near-field beam patterns of the second-stage subarray. The computational efficiency is significantly improved as compared with the traditional methods, while achieving the similar resolutions. In addition, a multi-FPGA signal processor is proposed for implementing the underwater 3-D imaging.

Object recognition and clustering are useful techniques in pattern recognition and computer vision. Traditionally, these techniques have been implemented by visual-feature-based methods. However, these methods may not adequately tackle the differences in the shapes and colors of objects. In this paper, we propose an alternative method in which objects of different colors, or even different shapes, function similarly. If text strings are visible on their surfaces, we can extract the semantic features of objects, thereby recognizing and clustering them. Thus, this method is based on semantic information. The method is experimentally tested on a dataset of images containing the packing cases of commercial products. Semantic information in the dataset images is retrieved using text extraction modules, passed through an internet data mining module and is finally described and clustered. The final clustering results are more accurate than those obtained by visual-feature-based methods.

作者： V. Senthooran L. Ranathunga Department of Information Technology University of Moratuwa Sri Lanka

Imperceptibility and the embedding capacity are the two most important aspects to be concerned in any image based steganographic research studies. It is necessarily considered to maximize the amount of embedding capacity while preserving the security against detection by unauthorized people in any steganographic methods. Many research studies have exposed that the modified quantization tables significantly reduce the distortion in the quality of stego-images and increase the embedding capacity of stego-images in DCT based steganographic techniques. In this paper, we investigate the aforementioned requirements in JPEG based steganographic techniques with the existing quantization table modification techniques by evaluating the experimental results and derive modified quantization tables to compare the previous results of some existing quantization modification techniques. Our experimental results reveal that the modified tables can provide a significance improvement in information-hiding capacity and visual quality than the other methods tested.

An efficient sparse antenna array architecture is developed for coherent imaging of sparse but otherwise unknown scenes. In this architecture, the array elements form a periodic nonuniform pattern. Using analysis that explicitly takes into account the presence of noise, we develop an efficient pattern design procedure based on co-arrays, describe an efficient scene support recovery algorithm as part of image reconstruction in the form of a modification to the MUSIC algorithm, and discuss a failure detection technique based on evaluating "back-projection" error. Since our development exploits a close connection to multi-coset sampling of bandlimited waveforms, our results may in turn may also be useful in the design of those systems.

Web accessibility of MOOCs for elderly students

Web accessibility of MOOCs for elderly students

international conference on Information technology based Higher Education and Training, ITHET

作者： Sandra Sanchez-Gordon Sergio Luján-Mora Department of Informatics and Computer Science National Polytechnic School Quito Ecuador Department of Software and Computing Systems University of Alicante Alicante Spain

internet use by older people has increased dramatically during the past 10 years. According to different sources, the number of users over age 65 has more than doubled since 2000. Besides, the inevitable effect of younger users aging will increase the number of older people using the internet the next decades. Unfortunately, older people face several challenges when using the web due to diminishing capacities related to aging, such as vision decline, hearing loss, decremented motor skills and cognition issues. On the other hand, e-learning can be an opportunity in helping older people become integrated with the rest of society. In this context, Massive Open Online Courses (MOOC) bring great opportunities to enhance the quality of life of older people by enabling lifelong learning and inclusion in learning communities. However, MOOCs can present some barriers that could hamper full participation by elderly students. In order to avoid these barriers, MOOCs have to meet different user needs, skills and situations: MOOCs have to successfully address web accessibility challenges for elderly students. The purpose of this paper is to raise awareness towards a better understanding of the web accessibility challenges that elderly students of MOOCs face.

Scalable face image retrieval is an important and challenging issue in many real world applications such as security and surveillance systems. However, the current available face recognition approaches are facing the challenge of handling large-scale datasets due to their high dimensionality of features. Meanwhile, most of the proposed retrieval methods fail to take full advantage of useful information such as age and gender. To address the above issues and build a practical face image retrieval system, this paper proposes a multi-feature quantization method to quantize both component-based and global geometric features, based on which the candidate images can be discriminated. Afterwards, a re-ranking algorithm constrained by the classification performance is proposed to select the top ranked images as the final retrieval results. Experimental results have been illustrated and analyzed to show that the proposed methods outperform the state-of-art methods and achieve good face image retrieval results.
