Search based software engineering: Trends, techniques and applications

© ACM, 2012. This is the author's version of the work. It is posted here by permission of ACM for your personal use. Not for redistribution. The definitive version is available from the link below.In the past five years there has been a dramatic increase in work on Search-Based Software Engineering (SBSE), an approach to Software Engineering (SE) in which Search-Based Optimization (SBO) algorithms are used to address problems in SE. SBSE has been applied to problems throughout the SE lifecycle, from requirements and project planning to maintenance and reengineering. The approach is attractive because it offers a suite of adaptive automated and semiautomated solutions in situations typified by large complex problem spaces with multiple competing and conflicting objectives. This article provides a review and classification of literature on SBSE. The work identifies research trends and relationships between the techniques applied and the applications to which they have been applied and highlights gaps in the literature and avenues for further research.EPSRC and E

Approaches for Automated Object Recognition and Extraction from Images — a Study

Digital Image Interpretation is one of the most challenging and important tasks in many scientific and engineering applications. The two vital subtasks in image interpretation are recognition and extraction of object(s) of interest (OOI) from an image. When such tasks are manually performed, it calls for human experts, making them more time consuming, less cost effective and highly constrained. These negative factors led to the development of a computer system which performed an automatic analysis of visual information in order to bring in consistency, efficiency and accuracy in image analysis. This paper focuses on the survey of various existing automated approaches for recognition and extraction of OOI from an image in various scientific and engineering applications. In this work a categorization of these approaches is made based on the four principle factors (Input, Object, Feature, Attention) with which each approach is driven. Most of the approaches discussed in this paper are proved to work efficiently in real environments
