SweepLSD: New line segment detector offers speed and memory efficiency

By PulseAugur Editorial · [1 sources] ·

Researchers have developed SweepLSD, a novel line segment detector that processes images in a single pass with memory usage proportional to image width, rather than pixel count. This algorithm, detailed in a master's thesis from 2014, features an integer-only core and has been implemented in open-source C++17 and an FPGA realization. The FPGA version can process live 1080p30 video on older hardware without external memory, while the CPU implementation is significantly faster than previous detectors on various benchmarks, including vanishing-point estimation and camera-attitude applications.

    SweepLSD: A One-Pass, O(width)-Memory Line Segment Detector with an Integer-Only Streaming Core and a Real-Time FPGA Realization

    We present SweepLSD, a line segment detector that reads the image exactly once and emits each segment within a few rows of its last pixel passing the scan line. Every stage, including connected-component labeling and the final line test, processes the image as a row stream: inter…
