Learning Human Poses from Actions
People Involved : Aditya Arun, C. V. Jawahar and M. Pawan Kumar
We consider the task of learning to estimate human pose in still images. In order to avoid the high cost of full supervision, we propose to use a diverse data set, which consists of two types of annotations: (i) a small number of images are labeled using the expensive ground-truth pose; and (ii) other images are labeled using the inexpensive action label. As action information helps narrow down the pose of a human, we argue that this approach can help reduce the cost of training without significantly affecting the accuracy.

Projects
Scene Text Recognition in Indian Scripts
People Involved : Minesh Mathew, Mohit Jain and CV Jawahar
This work addresses the problem of scene text recognition in India scripts. As a first step, we benchmark scene text recognition for three Indian scripts - Devanagari, Telugu and Malayalam, using a CRNN model.
RoadText-1K: Text Detection & Recognition Dataset for Driving Videos
People Involved :Sangeeth Reddy, Minesh Mathew, Lluis Gomez, Marçal Rusinol, Dimosthenis Karatzas, and C. V. Jawahar
Perceiving text is crucial to understand semantics of outdoor scenes and hence is a critical requirement to build intelligent systems for driver assistance and self-driving. Most of the existing datasets for text detection and recognition comprise still images and are mostly compiled keeping text in mind.
LectureVideoDB - A dataset for text detection and Recognition in Lecture Videos
People Involved : Kartik Dutta, Minesh Mathew, Praveen Krishnan and CV Jawahar
Lecture videos are rich with textual information and to be able to understand the text is quite useful for larger video understanding/analysis applications. Though text recognition from images have been an active research area in computer vision, text in lecture videos has mostly been overlooked. In this work, we investigate the efficacy of state-of-the art handwritten and scene text recognition methods on text in lecture videos
Word level Handwritten datasets for Indic scripts
People Involved : Kartik Dutta, Praveen Krishnan, Minesh Mathew and CV Jawahar
Handwriting recognition (HWR) in Indic scripts is a challenging problem due to the inherent subtleties in the scripts, cursive nature of the handwriting and similar shape of the characters. Lack of publicly available handwriting datasets in Indic scripts has affected the development of handwritten word recognizers. In order to help resolve this problem, we release 2 handwritten word datasets: IIIT-HW-Dev, a Devanagari dataset and IIIT-HW-Telugu, a Telugu dataset.
Unconstrained OCR for Urdu using Deep CNN-RNN Hybrid Networks
People Involved : Mohit Jain, Minesh Mathew, C. V. Jawahar
Building robust text recognition systems for languages with cursive scripts like Urdu has always been challenging. Intricacies of the script and the absence of ample annotated data further act as adversaries to this task. We demonstrate the effectiveness of an end-to-end trainable hybrid CNN-RNN architecture in recognizing Urdu text from printed documents, typically known as Urdu OCR. The solution proposed is not bounded by any language specific lexicon with the model following a segmentation-free, sequence-tosequence transcription approach. The network transcribes a sequence of convolutional features from an input image to a sequence of target labels.
Unconstrained Scene Text and Video Text Recognition for Arabic Script
People Involved : Mohit Jain, Minesh Mathew, C. V. Jawahar
Building robust recognizers for Arabic has always been challenging. We demonstrate the effectiveness of an end-to-end trainable CNN-RNN hybrid architecture in recognizing Arabic text in videos and natural scenes. We outperform previous state-of-the-art on two publicly available video text datasets - ALIF and AcTiV. For the scene text recognition task, we introduce a new Arabic scene text dataset and establish baseline results. For scripts like Arabic, a major challenge in developing robust recognizers is the lack of large quantity of annotated data. We overcome this by synthesizing millions of Arabic text images from a large vocabulary of Arabic words and phrases.
