Image processing techniques for offline handwritten recognition

Abstract: India is a country where many languages exist. Major languages of India are written in Devnagari script like Marathi, Bangla, Hindi, Sanskrit, or Nepali etc. In the world, the third most popular language is Hindi. In the era of computers, the need of recognizing printed as well as handwritten information has become a vital part. Significant improvement has been seen in the area of offline script recognition in Devnagari script. In this review paper, feature extraction and classification techniques are reviewed and the comparison of various techniques is done on the basis of accuracy.

Test Cases Prioritization using model based test dependencies: A survey

Abstract: Software Testing is a part of software engineering which helps to identify failure or defect in advance to give quality to the product. Regression testing is an important aspect of testing field in which modified part of the software will be tested to ensure that no new errors will be generated into previously tested code. Regression test suite is typically large so that a method or technique should select for test cases which will give effectiveness to the software and also reduces the overall cost. In this kind of situation test case prioritization technique is used to give the effectiveness to the software. It organizes test cases in an order such that, test case having high priority will be executed first through which effectiveness will be increases. Performance goal of test case prioritization is fault detection; number of faults will be detected quickly during testing process, code coverage and reliability.

Gate leakage current reduction in IP3 SRAM cells at 45 nm CMOS technology for multimedia applications

Abstract: We have presented an analysis of the gate leakage current of the IP3 static random access memory (SRAM) cell structure when the cell is in idle mode (performs no data read/write operations) and active mode (performs data read/write operations), along with the requirements for the overall standby leakage power, active write and read powers. A comparison has been drawn with existing SRAM cell structures, the conventional 6T, PP, P4 and P3 cells. At the supply voltage, VDD = 0.8 V, a reduction of 98%, 99%, 92% and 94% is observed in the gate leakage current in comparison with the 6T, PP, P4 and P3 SRAM cells, respectively, while at VDD = 0.7 V, it is 97%, 98%, 87% and 84%. A significant reduction is also observed in the overall standby leakage power by 56%, the active write power by 44% and the active read power by 99%, compared with the conventional 6T SRAM cell at VDD = 0.8 V, with no loss in cell stability and performance with a small area penalty. The simulation environment used for this work is 45 nm deep sub-micron complementary metal oxide semiconductor (CMOS) technology, tox = 2.4 nm, Vthn = 0.22 V, Vthp = 0.224 V, VDD = 0.7 V and 0.8 V, at T = 300 K.

Image encryption based on watermarking technique in fourier domain using pixel scrambling

Abstract: In this paper a technique has been proposed that enhances the security level by concealing an image inside another. The method uses Fourier transform with random phase masks to make it imperceptible by obscuring the secret image. It further makes use of scrambling to enhance the integrity of the image. Computer simulations have been carried out in order to prove the results obtained. Furthermore, peak Signal to noise ratio along with the effects of occlusion have also been assessed. The proposed scheme has been subjected to various attacks for steganalysis and the corresponding values of Correlation coefficients, Standard Deviation error and mean error are contemplated.

The numerical study of advection–diffusion equations by the fourth-order cubic B-spline collocation method

Abstract: A fourth-order numerical method based on cubic B-spline functions has been proposed to solve a class of advection–diffusion equations. The proposed method has several advantageous features such as high accuracy and fast results with very small CPU time. We have applied the Crank–Nicolson method to solve the advection–diffusion equation. The stability analysis is performed, and the method is shown to be unconditionally stable. Error analysis is carried out to show that the proposed method has fourth-order convergence. The efficiency of the proposed B-spline method has been checked by applying on ten important advection–diffusion problems of three types, having Dirichlet, Neumann and periodic boundary conditions. Considered examples prove the mentioned advantages of the method. The computed results are also compared with those available in the literature, and it is found that our method is giving better results.
