deepfeatembed logoDeep Feature Embedding for Accurate Recognition and Retrieval of Handwritten Text

People Involved : Praveen Krishnan, Kartik Dutta and C. V. Jawahar

We propose a deep convolutional feature representation that achieves superior performance for word spotting and recognition for handwritten images. We focus on :- (i) enhancing the discriminative ability of the convolutional features using a reduced feature representation that can scale to large datasets, and (ii) enabling query-by-string by learning a common subspace for image and text using the embedded attribute framework. We present our results on popular datasets such as the IAM corpus and historical document collections from the Bentham and George Washington pages.

People Involved : Praveen Krishnan and C. V. Jawahar

We address the problem of predicting similarity between a pair of handwritten document images written by different individuals. This has applications related to matching and mining in image collections containing handwritten content. A similarity score is computed by detecting patterns of text re-usages between document images irrespective of the minor variations in word morphology, word ordering, layout and paraphrasing of the content.

 

 

visualaestheticVisual Aesthetic Analysis for Handwritten Document Images

People Involved : Anshuman Majumdar, Praveen Krishnan and C. V. Jawahar

We  present  an  approach  for  analyzing  the  visual aesthetic  property  of  a  handwritten  document  page  which matches  with  human  perception.  We  formulate  the  problem at two independent levels: (i) coarse level which deals with the overall layout, space usages between lines, words and margins, and (ii) fine level, which analyses the construction of each word and  deals  with  the  aesthetic  properties  of  writing  styles.  We present our observations on multiple local and global features which can extract the aesthetic cues present in the handwritten documents.
