Localizing Infinity-shaped fishes: Sketch-guided object localization in the wild

no code implementations24 Sep 2021 Pau Riba, Sounak Dey, Ali Furkan Biten, Josep Llados

This work investigates the problem of sketch-guided object localization (SGOL), where human sketches are used as queries to conduct the object localization in natural images.

One-shot Compositional Data Generation for Low Resource Handwritten Text Recognition

no code implementations11 May 2021 Mohamed Ali Souibgui, Ali Furkan Biten, Sounak Dey, Alicia Fornés, Yousri Kessentini, Lluis Gomez, Dimosthenis Karatzas, Josep Lladós

Low resource Handwritten Text Recognition (HTR) is a hard problem due to the scarce annotated data and the very limited linguistic information (dictionaries and language models).

Multi-Modal Reasoning Graph for Scene-Text Based Fine-Grained Image Classification and Retrieval

1 code implementation21 Sep 2020 Andres Mafla, Sounak Dey, Ali Furkan Biten, Lluis Gomez, Dimosthenis Karatzas

Scene text instances found in natural images carry explicit semantic information that can provide important cues to solve a wide array of computer vision problems.

Doodle to Search: Practical Zero-Shot Sketch-based Image Retrieval

1 code implementation CVPR 2019 Sounak Dey, Pau Riba, Anjan Dutta, Josep Llados, Yi-Zhe Song

Highly abstract amateur human sketches are purposefully sourced to maximize the domain gap, instead of ones included in existing datasets that can often be semi-photorealistic.

Learning Cross-Modal Deep Embeddings for Multi-Object Image Retrieval using Text and Sketch

no code implementations28 Apr 2018 Sounak Dey, Anjan Dutta, Suman K. Ghosh, Ernest Valveny, Josep Lladós, Umapada Pal

In this work we introduce a cross modal image retrieval system that allows both text and sketch as input modalities for the query.

Evaluation of the Effect of Improper Segmentation on Word Spotting

no code implementations21 Apr 2016 Sounak Dey, Anguelos Nicolaou, Josep Llados, Umapada Pal

Word spotting is an important recognition task in historical document analysis.

Local Binary Pattern for Word Spotting in Handwritten Historical Document

no code implementations20 Apr 2016 Sounak Dey, Anguelos Nicolaou, Josep Llados, Umapada Pal

Digital libraries store images which can be highly degraded and to index this kind of images we resort to word spot- ting as our information retrieval system.
