Looking 3D: Anomaly Detection with 2D-3D Alignment
Ankan Bhunia, Changjian Li, Hakan Bilen
Automatic anomaly detection based on visual cues holds practical significance in various domains, such as manufacturing and product quality assessment. This paper introduces a new…
Odd-One-Out: Anomaly Detection by Comparing with Neighbors
Ankan Bhunia, Changjian Li, Hakan Bilen
This paper introduces a novel anomaly detection (AD) problem aimed at identifying `odd-looking' objects within a scene by comparing them to other objects present. Unlike traditiona…
Generative Multiplane Neural Radiance for 3D-Aware Image Generation
Amandeep Kumar, Ankan Kumar Bhunia, Sanath Narayan +5
We present a method to efficiently generate 3D-aware high-resolution images that are view-consistent across multiple target views. The proposed multiplane neural radiance model, na…
Cross-modulated Few-shot Image Generation for Colorectal Tissue Classification
Amandeep Kumar, Ankan kumar Bhunia, Sanath Narayan +4
In this work, we propose a few-shot colorectal tissue image generation method for addressing the scarcity of histopathological training data for rare cancer tissues. Our few-shot g…
DoodleFormer: Creative Sketch Drawing with Transformers
Ankan Kumar Bhunia, Salman Khan, Hisham Cholakkal +4
Creative sketching or doodling is an expressive activity, where imaginative and previously unseen depictions of everyday visual objects are drawn. Creative sketch image generation…
Handwriting Transformers
Ankan Kumar Bhunia, Salman Khan, Hisham Cholakkal +3
We propose a novel transformer-based styled handwritten text image generation approach, HWT, that strives to learn both style-content entanglement as well as global and local writi…
Handwriting Recognition in Low-resource Scripts using Adversarial Learning
Ayan Kumar Bhunia, Abhirup Das, Ankan Kumar Bhunia +2
Handwritten Word Recognition and Spotting is a challenging field dealing with handwritten text possessing irregular and complex shapes. The design of deep neural network models mak…
A Deep One-Shot Network for Query-based Logo Retrieval
Ayan Kumar Bhunia, Ankan Kumar Bhunia, Shuvozit Ghose +3
Logo detection in real-world scene images is an important problem with applications in advertisement and marketing. Existing general-purpose object detection methods require large…
Improving Document Binarization via Adversarial Noise-Texture Augmentation
Ankan Kumar Bhunia, Ayan Kumar Bhunia, Aneeshan Sain +1
Binarization of degraded document images is an elementary step in most of the problems in document image analysis domain. The paper re-visits the binarization problem by introducin…
Indic Handwritten Script Identification using Offline-Online Multimodal Deep Network
Ayan Kumar Bhunia, Subham Mukherjee, Aneeshan Sain +3
In this paper, we propose a novel approach of word-level Indic script identification using only character-level data in training stage. The advantages of using character level data…
Staff line Removal using Generative Adversarial Networks
Aishik Konwer, Ayan Kumar Bhunia, Abir Bhowmick +4
Staff line removal is a crucial pre-processing step in Optical Music Recognition. It is a challenging task to simultaneously reduce the noise and also retain the quality of music s…
Script Identification in Natural Scene Image and Video Frame using Attention based Convolutional-LSTM Network
Ankan Kumar Bhunia, Aishik Konwer, Ayan Kumar Bhunia +3
Script identification plays a significant role in analysing documents and videos. In this paper, we focus on the problem of script identification in scene text images and video scr…
Signature Verification Approach using Fusion of Hybrid Texture Features
Ankan Kumar Bhunia, Alireza Alaei, Partha Pratim Roy
In this paper, a writer-dependent signature verification method is proposed. Two different types of texture features, namely Wavelet and Local Quantized Patterns (LQP) features, ar…
