- Abstract: Detecting local features, such as corners, segments or blobs, is the first
step in the pipeline of many Computer Vision applications. Its speed is crucial
for real time applications. In this paper we present ELSED, the fastest line
segment detector in the literature. The key for its efficiency is a local
segment growing algorithm that connects gradient aligned pixels in presence of
small discontinuities. The proposed algorithm not only runs in devices with
very low end hardware, but may also be parametrized to foster the detection of
short or longer segments, depending on the task at hand. We also introduce new
metrics to evaluate the accuracy and repeatability of segment detectors. In our
experiments with different public benchmarks we prove that our method is the
most efficient in the literature and quantify the accuracy traded for such
gain.

We incorporate geometric constraints in an end-to-end manner into a typical segmentation based model and bridge the intermediate dense classification task with the targeted pose estimation one.
Our model is experimentally shown to achieve similar results with marker-based methods and outperform the markerless ones, while also being robust to the pose variations of the calibration structure.
