Detailed Description

This class implements the method: [Suárez], I., Buenaposada, J. M., & Baumela, L. (2021). ELSED: Enhanced Line SEgment Drawing. arXiv preprint arXiv:2108.03144.

It is an efficient line segment detector amenable to use in low power devices such as drones or smartphones. The method takes an image as input and outputs a list of detected segments.

detect()

Segments upm::ELSED::detect

(

const cv::Mat &

image

)

Detects segments in the input image.

Parameters

image

An input image. The parameters are adapted to images of size 640x480. Bigger images will generate more segments.

Returns

The list of detected segments
