2 Software Quality Assurance in Internet of Things

Authors: Marwah, Q. Mateen, M. Sirshar

Abstract:

Internet of Things (IoT) is increasing the connectedness of things and people on a scale that was not imaginable before. The pace of adoption of IoT in market is increasing due to ubiquitous computing and increase in the connectedness of machines and people. But very few parameters exist to check and ensure the quality of IoT implemented devices and machines. The paper is the comprehensive survey of techniques and methodologies used for the implementing IoT. Based on the defined criteria of evaluation, we have done analysis and compared techniques and have finally concluded that most of the IT implementation techniques lack tool support. Because of the increasing use of IoT, an increasing trend towards its implementation in real time systems has also been observed. The paper assesses strong and weak points of techniques and draws a conclusion at the end.

1 Design and Performance Analysis of Advanced B-Spline Algorithm for Image Resolution Enhancement

Authors: M. Z. Kurian, M. V. Chidananda Murthy, H. S. Guruprasad

Abstract:

An approach to super-resolve the low-resolution (LR) image is presented in this paper which is very useful in multimedia communication, medical image enhancement and satellite image enhancement to have a clear view of the information in the image. The proposed Advanced B-Spline method generates a high-resolution (HR) image from single LR image and tries to retain the higher frequency components such as edges in the image. This method uses B-Spline technique and Crispening. This work is evaluated qualitatively and quantitatively using Mean Square Error (MSE) and Peak Signal to Noise Ratio (PSNR). The method is also suitable for real-time applications. Different combinations of decimation and super-resolution algorithms in the presence of different noise and noise factors are tested.
