ufl_scene_text_recognition

C++ (OpenCV) implementation of the Unsupervised Feature Learning algorithm of Adam Coates and Andrew Ng for Scene Text Detection and Recognition

Content

  • ./ source code for scene text recognition. Depends on OpenCV >= 3.0-beta and liblinear >= 1.94 (included) and blas (part of liblinear but maybe potentially replaced by libblas system lib).

  • liblinear-1.94/ snapshot of liblinear in order to be able to reproduce exactly the same model.

  • train/ source code and data to build the filter bank, extract train/test features, and train the linear classifier. See train/README

Compilation

 cmake .
 make

Usage

 ./ufl_predict_char train/all_train_data.liblinear.model_s2 train/data/all_train_data.svm.range train/first_layer_centroids.xml train/data/sample/img_1.pgm

./ufl_predict_word train/all_train_data.liblinear.model_s7 train/data/all_train_data.svm.range train/first_layer_centroids.xml train/data/sample/china.jpg
