Human perception in segmentation of sketches
In this paper, we study the segmentation of sketched engineering
drawings into a set of straight and curved segments. Our immediate objective is
to produce a benchmarking method for segmentation algorithms. The criterion
is to minimise the differences between what the algorithm detects and what
human beings perceive. We have created a set of sketched drawings and have
asked people to segment them. By analysis of the produced segmentations, we
have obtained the number and locations of the segmentation points which
people perceive. Evidence collected during our experiments supports useful
hypotheses, for example that not all kinds of segmentation points are equally
difficult to perceive. The resulting methodology can be repeated with other
drawings to obtain a set of sketches and segmentation data which could be used
as a benchmark for segmentation algorithms, to evaluate their capability to
emulate human perception of sketches
