PhD Research Summary: (view a talk about most of the work)

I work in the graphics recognition filed. This deals with symbols and line drawings (such as all kinds of engineering drawings, comics, graphs and logos). I apply techniques from computer vision, pattern recognition, human visual perception and information retrieval. The goals of my research are:
  • Automatic interpretation of technical line drawings
  • Reliable and efficient symbol retrieval form large technical line drawing databases.
My approach to achieve these goals has two main complementary directions. First, the recognition of the symbols, both isolated recognition and in-context spotting, which enables us to automatically analyze line drawings. Second, the off-line content analysis of line drawings, which makes us able to index the documents and the regions inside them for later fast retrieval.

For realizing my approach, I use geometric matching techniques for recognizing and spotting symbols. The use of shape features and geometry has been shown to be very suitable for line drawings. As for content analysis, it is based on finding repeating symbols patterns and clustering them in an indexable symbol library. Finding the patterns is based on statistically justified grouping method. All my methods have been applied on standard datasets and have achieved significantly better results for retrieval than the state-of-the-art approaches.

This work has the ultimate goal of the automatic understanding of general line drawings that contain all kinds of symbols. For future work, I like to investigate how humans recognize images of line drawings (texture-less shapes).
