  • Two Different Types of Soft Near-Fields

    • Authors: Emin Aygun, H¨useyin Kamacı
      Abstract: Molodtsov’s soft set is a novel mathematical approach to ad-dress models containing uncertainty. The algebraic structures of this set approach are prominent issues. The main objective of this paper is to con-tribute algebraic structures in the soft set theory. Relatedly, the notions of soft intersection near-field and soft union near-field, and their fundamental properties are introduced. Also, some findings and results related to the emerging soft algebraic structures are included.

  • Detection of R- Peaks in Electrocardiogram based onWavelet Transform and
           Wavelet Approximation

    • Authors: Imtiyaz Ahmad Wani, Afroz -, Rayees Ahmad
      The diseases which are associated with the human heart can be detected through a procedure known as the electrocardiogram that is an electrical activity of the human heart. The clinical analysis of ECG faces problems in its interpretation due to the poor recording environment where unwanted noise is getting contaminated into it in the form of different artifacts viz motion artifacts, loose lead artifact, baseline wandering, muscle tumour artifacts etc. To get noise-free electrocardiogram wavelet theory plays an important role. This paper talks about the framework of approximation of an electrocardiogram signal by wavelet theory. On obtaining the denoised electrocardiogram, prominent peaks and R peaks -part of QRS complex are detected. The proposed algorithm is applied to the ECG recording No. 100m.mat obtained from MIT-BIH database

  • Efficiently Guided Active Contours for Image Segmentation

    • Authors: Lutful Mabood, Tahir Ullah, Haider Ali, Noor Badshah
      Abstract: Segmenting natural and outdoor images are challenging for most of the latest variational segmentation models. For this purpose we employ derived image data (DID) and propose a robust variational model. The DID rely on three images by utilizing image local and global statistics as well as filter image which is obtained through our design high pass filtering techniques. Then these derived image data are incorporated into our proposed energy functional which can robustly segment images having inhomogeneity, mix backgrounds and multi-regions. Furthermore, the results of DID are compared with other well known methods with finding Jaccard similarity index to proof the efficient and qualitative performance of proposed model over the traditional methods. Finally, the proposed DID based model is tested on real world 3D images to ensure that it also preserve its performance in vector valued images as well.
