**Kardo Aziz**has successfully defended his MSc thesis, titled Better Text Detection through Improved k-means-based Feature Learning. In his thesis, Kardo proposes a technique called*Visual Similarity Sampling (VSS)*, which selects training samples using the average similarity of image patches within and between text and non-text classes.
