The hyper spectral images are the complex ones those are taken from the low resolution cameras. These images are often degraded in the acquisition process due to the integrated so many different noises in it. These can include various types of noises as impulse noise, Gaussian noise, deadlines and stripes etc. This paper defines new hybrid image restoration method based on Linear Discriminative Analysis (LDA) and Low Rank Matrix Recovery (LRMR). The proposed approach works in two phase, first it converting an image into number of patches and treating each patch as a separate image, performance can be measured out and that patches induced in LRMR framework In second phase, for further improvement in image quality LDA approach is used.","PeriodicalId":144495,"journal":{"name":"2015 Third International Conference on Image Information Processing (ICIIP)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134317760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It's mainly focuses on the realization of CIC interpolator with various valuable factors like interpolation factor, differential delay and the used stages on the transmitted and received signal after passing the transmitted signal through CIC interpolator and received signal through the CIC decimator with the same parameters as interpolator. It also shows the effect of increment frequency of input signal on the CIC interpolator's output. Number of section determines the pass band attenuation and increment in this enhances the capability of the CIC interpolator but increase the roll off in filter pass band.

The most common form of gestures are signs used in different sign languages having both local and global motions. Recognition of these gestures require the hand trajectory both with respect to orientation in space among inter frames and distance among objects like face and hands among intra frames. In this paper, at first the face region and the two hand regions are detected. The centre of the face along with the centre of the two hands are then determined. This is then followed by tracking the hands trajectory following the centre both in terms of direction among consecutive frames as well as distance from the centre of the frame. The variations in the hand locations along with the centre of the face are considered for analysis. Finally the gestures are considered for recognition. The paper addresses a pertinent problem w.r.t the difference in the number of frames between a stored gesture and query gesture for matching. Experimental results show an accuracy of 86% in recognizing 24 gestures is maintained even after normalizing the number of frames by the proposed scheme.","PeriodicalId":144495,"journal":{"name":"2015 Third International Conference on Image Information Processing (ICIIP)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115327048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Image Fusion is a procedure of converging of two images or more than two images or mixing of the corresponding and also the basic components of set of comparative bended, inadequate or noised images, to create a resultant image. The prioritic requirement of image fusion for high determination on panchromatic and multispectral images for better vision with high resolution. In our proposed system there is discrete wavelet worked on higher level of spatial resolution with frequency coefficient bands, decomposed the source images with the fusion rule in to high and low levels of coefficient bands. By using enhanced laplacian pyramid technique, mapped the local binarized pixels of images within the region which is pixel by pixel fusion. E-Laplacian technique works on gray-scale images, colored or RGB images and medical images. The final step performed is an inverse DWT with the new band coefficients to construct the fused image. The Laplacian provides the enhanced results of fused images with more accuracy in PSNR, Entropy, SD, SSI, MI, and Average Gradient. In this paper we are comparing our proposed system with the existing methods of image fusion.","PeriodicalId":144495,"journal":{"name":"2015 Third International Conference on Image Information Processing (ICIIP)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115342297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the proposed approach the watermark is a coloured image which is embedded into the highest frequency subband of the primary image in its Contourlet domain. The rendered result gives a clear corroboration that the method is beneficial in embedding larger data into the subbands and provides high robustness without affecting the primary (host) image perceptibility. The proposed method has been tested under various watermarking attacks and results are tabulated yielding improved results by using Contourlet Transform for watermarking when compared to other techniques like DWT and SVD. The proposed approach proves to accommodate a larger payload, and yet fulfil the need of high perceptibility of the primary image without much degradation due to the presence of the watermark is itself robust in that it can resist many attacks, and it can be useful for fingerprinting applications.","PeriodicalId":144495,"journal":{"name":"2015 Third International Conference on Image Information Processing (ICIIP)","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117296934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The method which is used for the compression is Discrete Wavelet Transform (DWT), for recovery of the original image which we use for the Inverse Discrete Wavelet Transform (IDWT) and to get a secret code back which we use Decryption technique. A complete set of experiments is implemented to explain proposed method's applicability and assess the worth of its performance in resistance to Peak signal noise ratio and NPCR achieve the reason of information hiding with the use of secret bit of information by replacing the random noise, with the lowest plane of embedding secret information in order to avoid the noise and the security attacks, making use of the redundancy.

Computing ranking for such large number of web graph on a particular system, makes it prone to system failure and time taking. The present work proposes a distributed ranking system to attain fault tolerance and speedy calculation of Pagerank vector.

To reduce the computational expense, instead of applying CS to the entire image, it is judicious if CS were applied in blocks. Sensing an image block by block not only requires lesser memory but also eases the computational burden during reconstruction. Although a large amount of work has been done in integrating CS and OFDM, empirical analysis of BCS in conjugation with OFDM has not been done so far. This work senses an image using Block Compressed Sensing (BCS), encodes it using DPCM and transmits it in the OFDM framework Among the reconstruction algorithms OMP and SPL, this paper attempts to come up with the superior algorithm after performing a detailed comparison by varying block sizes, sub-sampling rates per block and the AWGN channel SNR.
