Source code reviews on mobile devices

Frącz W., Dajda J.

Computer Science

2016

Vol. 17 (2)

143--161

This paper presents the results of an experiment-driven investigation on the efficiency of source code review practice performed on mobile devices. In particular, the conducted investigation tries to verify whether or not the small screens of mobile devices influence the speed and quality of the review process. Besides presenting the experiment itself and discussing the obtained results, this paper also describes the dedicated Android application for mobile code reviews that was implemented for research purposes.

The length of digital curves

Klette R., Yip B.

Machine Graphics and Vision

2000

Vol. 9, No. 3

673-703

The aper discusses one of the elementary subjects in image analysis: how to measure the lenght of a digital curve. A digital curve in the plane is defined to be a cycle given either as an alternating sequence of vertices and edges, or an alternating sequence of edges and squares. The paper reports about two lenght estimators, one based on the partition of a frontier of a simply-connected isothetic polygon into digital straight segments, and one based on calculating the minimum-lenght polygon within an open boundary of a simply-connected isothetic polygon. Both techniques are known to be implementations of covergent estimators of the perimeter of bounded, polygonal or smooth convex sets in the euclidean plane. For each technique a linear-time algorithm is specified, and both algorithms are compared with respect to convergence speed and number of generated segments. The experiments show convergent behavior also for perimeters of non-convex bounded subsets of the euclidean plane.
