4-Weighted Fractional Fourier Transform based Multiple Image Encryption Approach with PAN
Get PDFIn this manuscript, a new encryption approach for multiple images is proposed based on 4-weighted fractionalfrequency transform (4-WFRFT) domain. First, the low frequency-components of all the images are obtained byapplying Fourier Transform on each image, which positioned at corner position of image, shifted to the centralposition. Low-frequency component of each individual image is then scrambled with help of Arnold cat mapwith its parameters and combined all scrambled image to form a single image with the same size that of originalimage which is now ready for encryption process. Here, parameters of Arnold cat map and transform order of 4-WFRFT treated as secret keys which are converted from Permanent Account Number (PAN) of authorize person.The encrypted image information generated by authorize person can be recovered by applying PAN at receiverside
Packrat Parsing with Dynamic Buffer Allocation
Get PDFPackrat parsing is a type of recursive decent parsing with guaranteed liner time parsing. For this,memoization technique is implemented in which all parsing results are memorized to avoid repetitive scanningof inputs in case of backtracking. The issue with this technique is large heap consumption for memoization whichout weigh the benefits. In many situations the developers need to make a tough decision of not implementingpackrat parsing despite the possibility of exponential time parsing. In this paper we present our developedtechnique to avoid such a tough choice. The heap consumption is upper bounded since memorized results arestored in buffer, capacity of which is decided at runtime depending on memory available in the machine. Thisdynamic buffer allocation is implemented by us in Mouse parser. This implementation achieves stableperformance against a variety of inputs with backtracking activities while utilizing appropriate size of memoryfor heap

Boron Nanoparticle Image Analysis using Machine Learning Algorithms
Get PDFThe effort of digital image processing involves efficient computation aimed at developing an economical, fasterand more accurate, and cost-effective automated system. The objective of this paper is to ascertain and categorizeBoron nanoparticles (BNP) using digital image processing techniques. The spatial features are unsheathed fromthe Boron nanoparticle Transmission Electron Microscope (TEM) images using different segmentationtechniques, namely; Fuzzy C -means (FCM) and K-means. The size of Boron nanoparticles is determined andcategorized based on the area(size) in the microsize.The synthesization and characterization of Boronnanoparticles play an important role as an elementary procedure for the formation of Boron nanoparticles. Theresults are analyzed, interpreted and comparison is done with the manual values to observe the efficacy of theresults. It is observed that the K-means segmentation technique yields a smaller amountof error (5.87%) ascompared with Fuzzy C-mean(16.78%). Hence, it is considered that the K-Means is the most relevantsegmentation technique for Boron nanoparticle image analysis and categorization. The statistical test ofsignificance is applied using the Chi-square testing method (at 5% of significance level) to check the relationshipbetween the manual results and the algorithm results.The proposed study also establishes collaborative researchwork between Chemistry and Computer Science departments to develop computational research on theseplatforms
A Competent Convolutional Sparse Representation Model for Pan-Sharpening of Multi-Spectral Images
Get PDFTwo types of images are produced by Earth observation satellites, each having complementing spatial andspectral characteristics. Pan-sharpening (PS) is based on remote sensing and image fusion approach thatproduces a high spatial resolution multi-spectral image by merging spectral information from a low spatialresolution multispectral (MS) image with intrinsic spatial details from a high spatial resolution panchromatic(PAN) image. Traditional pan-sharpening methods continue to seek for a fused image that contains thenecessary spatial and spectral information. This work proposes a pan-sharpening method based on a recentinvention, convolutional sparse representation (CSR). Geometric structural characteristics are extracted fromthe PAN image using a CSR-based filtering procedure. The challenge of learning filters, convolutional basispursuit denoising (CBPDN), is handled using a modified dictionary learning method based on the concept ofAlternating Direction Method of Multipliers (ADMM). The retrieved details are put into MS bands usingapplicable weighting coefficients. Because the proposed fusion model avoids the standard patch-basedmethod, spatial and structural features are preserved while spectral quality is maintained. The spectraldistortion index SAM and the spatial measure ERGAS improve by 4.4 and 6.2 percent, respectively, whencompared to SR-based techniques. The computational complexity is reduced by 200 seconds when compared
to the most recent SR-based fusion technique. The proposed method's efficacy is demonstrated by reduced-scale and full-scale experimental findings utilising the QuickBird and GeoEye-1 datasets

Get PDFMoringa oleifera is a genus that is widely distributed in the moringeneric family. It contains micronutrients and other phytochemicals such as carotenoids. Moringa seeds are an excellent source of vitamin B6, C, Provit A such as beta-carotene, magnesium and protein among other nutrients. This study aimed to develop Moringa seed powder incorporated with an Indian savoury snack (Karasev), analyze its nutrients, and evaluate the shelf life of the products. In this study, Moringa seed powder was incorporated with the Indian savoury snack (Karasev), and four varieties (10,20,30, and 40%) and their sensory properties were tested. Protein and calcium nutrient analyses were performed. Additional shelf-life research was conducted for one month on nutrient and microbial analysis. Moringa seed powder incorporated in Indian savoury snack (Karasev) (10 %) is acceptable for organoleptic studies. Incorporated products contain more protein and calcium than standard products. The selected product was organoleptically acceptable for up to 30 days without microbial deterioration when stored in a zip-lock cover and an airtight container. Finally, since much evidence is available on the health benefits of moringa leaves, reports about moringa seeds are very limited; therefore, further research is needed to document the health benefits of moringa seeds and their potential implementation in various cookeries worldwide and make it a healthy diet
Plant Extracts as Alternative Therapeutic Agents for Anaemia: A Review
Get PDFAnaemia, one of the most common blood nutrition deficiency affecting at all ages of people. In Ayurveda, according to Acharya Charak, sign and symptoms of anaemia has close resemblance to Pandu Roga as like paleness, weakness, Heart Tonic, Eye Inflammation etc. As WHO claims, Anaemia is a medical situation in which the amount of RBCs or Hb count is lower than the normal individual and it is estimated that over 40 percent of children below age five are anaemic. On the basis of reported data plant extracts have been proved to be effective alternative therapy for the management of anaemic conditions. Physicians mostly prescribe iron-rich diet and vitamin supplements for the treatment of anaemia. Iron supplements are easily available in markets, if consumed prolonged, it can cause severe problems like gastro intestinal problems, hepatic disorders and sometimes even cause cancer. Hence, scientists are looking for an alternative for these iron supplements for the management of anaemia. Plant extracts could play a great role against anaemia. In this study, extracts of 20different plants as like- Solanum nigrum, Terminalia chebula, Beta Vulgaris etc. are discussed, which are experimentally proven to be effective in anaemia. Applications of these medicinal plants in anaemia is also mentioned in classical Ayurveda literature from ancient time. So, these plant extracts are may be an alternative therapy for the management of anaemia and this study could help researchers for research in anaemia and other related disorders
