BoundaryExtractor: Convolutional Recurrent Network for Road Boundary Extraction

August 2020

tl;dr: Extract road boundary with polylines.

Overall impression

There are several works from Uber ATG that extracts polyline representation based on BEV maps.

This work goes from the structured inference pipeline to an autoregressive convolutional snake (cSnake) pipeline. This is further extended to purely end-to-end RNN-based design in Polyline Loss and DAGMapper.
