It is important to characterize the noise accurately before including its structure in the formulations of algorithms. The distribution suggested in this paper is suitable for the ambient noise having kurtosis between 2.30 and 3. The ambient noise having low kurtosis is mainly dominated by shipping traffic which is having low frequency range.
Biometric palmprint identification is a technology used for identification and verification of palmprints using image acquisition, preprocessing, feature extraction and template matching. Even though the existing palmprint authentication systems have several advantages, there exist many disadvantages such as less accuracy, computational complexity, implementation expense, high resolution and storage...
In this study, we advocate the importance of robust local features that allow object form to be distinguished from other objects for detection purpose. We start from the grid of Histogram of oriented gradients (HOG) and integrate Scale Invariant Feature Transform (SIFT) within them. In HOG features an object's appearance is detected by the distribution of local intensity gradients or edge directions...
In food handling industry, grading of granular food materials is necessary because samples of material are subjected to adulteration. In the past, food products in the form of particles or granules were passed through sieves or other mechanical means for grading purposes. In this paper, analysis is performed on basmati rice granules; to evaluate the performance using image processing and Neural Network...
Over the past few years a lot of research are going in the field of reversible watermarking. Reversible watermarking is a novel category of watermarking schemes. It completely recover the watermark along with the original image. In starting this technique is only used for the authentication, now it is used to send highly informative information through the original image. This technique is mostly...
The advent of the internet age has led to the increase of prominent network security issues. Information encryption has long been a method used for information security. With the rapid development of parallel computing capacities of computer hardware, this method alone could not be trusted to ensure security by increasing the key sizes, thus bringing in the information hiding techniques into the scenario...
One of the emerging areas in image processing is color image enhancement. It is the process of improving image quality such as human visibility, edge sharpening, improving the contrast, etc. It is mainly applicable in medical images, satellite images. An algorithm for color image enhancement has been proposed that perform enhancement in red, green, blue components separately. These components are...
