Recognizing Gender from Human Facial Regions using Genetic Algorithm
Avirup Bhattacharyya, Rajkumar Saini, Partha Pratim Roy +2
Recently, recognition of gender from facial images has gained a lot of importance. There exist a handful of research work that focus on feature extraction to obtain gender specific…
Zone-based Keyword Spotting in Bangla and Devanagari Documents
Ayan Kumar Bhunia, Partha Pratim Roy, Umapada Pal
In this paper we present a word spotting system in text lines for offline Indic scripts such as Bangla (Bengali) and Devanagari. Recently, it was shown that zone-wise recognition m…
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…
Local Neighborhood Intensity Pattern: A new texture feature descriptor for image retrieval
Prithaj Banerjee, Ayan Kumar Bhunia, Avirup Bhattacharyya +2
In this paper, a new texture descriptor based on the local neighborhood intensity difference is proposed for content based image retrieval (CBIR). For computation of texture featur…
Word Searching in Scene Image and Video Frame in Multi-Script Scenario using Dynamic Shape Coding
Partha Pratim Roy, Ayan Kumar Bhunia, Avirup Bhattacharyya +1
Retrieval of text information from natural scene images and video frames is a challenging task due to its inherent problems like complex character shapes, low resolution, backgroun…
HMM-based Indic Handwritten Word Recognition using Zone Segmentation
Partha Pratim Roy, Ayan Kumar Bhunia, Ayan Das +2
This paper presents a novel approach towards Indic handwritten word recognition using zone-wise information. Because of complex nature due to compound characters, modifiers, overla…
HMM-based Writer Identification in Music Score Documents without Staff-Line Removal
Partha Pratim Roy, Ayan Kumar Bhunia, Umapada Pal
Writer identification from musical score documents is a challenging task due to its inherent problem of overlapping of musical symbols with staff lines. Most of the existing works…
Text Recognition in Scene Image and Video Frame using Color Channel Selection
Ayan Kumar Bhunia, Gautam Kumar, Partha Pratim Roy +2
In recent years, recognition of text from natural scene image and video frame has got increased attention among the researchers due to its various complexities and challenges. Beca…
Date-Field Retrieval in Scene Image and Video Frames using Text Enhancement and Shape Coding
Partha Pratim Roy, Ayan Kumar Bhunia, Umapada Pal
Text recognition in scene image and video frames is difficult because of low resolution, blur, background noise, etc. Since traditional OCRs do not perform well in such images, inf…
Multi-Oriented Text Detection and Verification in Video Frames and Scene Images
Aneeshan Sain, Ayan Kumar Bhunia, Partha Pratim Roy +1
In this paper, we bring forth a novel approach of video text detection using Fourier-Laplacian filtering in the frequency domain that includes a verification technique using Hidden…
