Localizing text in scene images using TextProposals algorithm + FCN supression

TextProposals with early FCN pruning

This is an improved version of the TextProposals algorithm by Lluis Gomez. It uses TextFCN to discard non-text regions, removing false positives and increasing the alforithm efficiency.

Publications

This work lead to two publications, which you may cite if using this improved TextProposals method or the TextFCN:

Usage:

For a detailed usage explanation refeer to TextProposals repo. This code is similar, but includes support to load heatmaps produced by TextFCN and prune regions. The FCN model toguether with the code to produce heatmaps and train it is available in the TextFCN repo.

img2hierarchy image_path classifier_path (heatmap_path) (suppression_threshold)

-image path and classifier_path are mandatory
-If no suppression_threshold is given, 0.10 will be used
-If no heatmap_path and suppression_threshold are given, initial suppression won't be used.
