Large Scale Sketch Based Image Retrieval Using Patch Hashing

  title={Large Scale Sketch Based Image Retrieval Using Patch Hashing},
  author={Konstantinos Bozas and Ebroul Izquierdo},
This paper introduces a hashing based framework that facilitates sketch based image retrieval in large image databases. Instead of exporting a single visual descriptor for every image, an overlapping spatial grid is utilised to generate a pool of patches. We rank similarities between a hand drawn sketch and the natural images in a database through a voting process where near duplicate in terms of shape and structure patches arbitrate for the result. Patch similarity is efficiently estimated… CONTINUE READING
