RNGDet implementation

[mjyun01]

Description

Code implementation for RNGDet: Road Network Graph Detection by Transformer in Aerial Images
Check rngdet/requirements.txt for Check the requirements.txt for the required configuration settings.

Type of change

• A new research paper code implementation

Tests

To train and evaluate new RNGDet network with cityscale dataset, follow descriptions in Readme.md.
Due to the randomness existing in both sampling and training, the final performance of the proposed models might be slightly different from the number reported in the original paper. Also, different threshold can make different results.

Test Configuration:

backbone = resnet50, num_quires = 10
extract_candidate_threshold = 0.65, candidate_filter_threshold = 25, alignment_distance = 10, logit_threshold = 0.75
More than 10 epoch training with default threshold settings makes reasonable result images.
