An Enhanced MSER Pruning Algorithm for Detection and Localization of Bangla Texts from Scene Images

Rashedul Islam, Rafiqul Islam, Kamrul Talukder
2019 ˜The œinternational Arab journal of information technology  
Firstly, MSER regions are generated from the input color image by converting it into gray scale image.  ...  The efficiency of text recognition depends on the efficiency of text localization. So, the main goal of the proposed method is to detect and localize text regions with high accuracy.  ...  They also developed a powerful low-level detector called CE-MSER which extends the widely used MSER by enhancing intensity contrast between text pattern and background.  ...

A Color-Based Interest Operator [chapter]

Marta Penas, Linda G. Shapiro
2009 Lecture Notes in Computer Science  
Our operator is closely related to the grayscale MSER but it works on the HSV color space, as opposed to the most popular operators in the literature, which are intensity based.  ...  It combines a fine and a coarse overlapped quantization of the HSV color space to find maximally stable extremal regions on each of its components and combine them into a final set of regions that are  ...  Also, the stability of the regions is fragile and very dependent on the input parameters. In this paper we present a color interest operator, called COLOR, based on the same principles as the MSER.  ...

Visual landmark generation and redetection with a single feature per frame

S Frintrop, A B Cremers
2010 2010 IEEE International Conference on Robotics and Automation  
The approach is based on the assumption that highly discriminative regions are easily redetectable in subsequent frames as well as in frames visited from different viewpoints.  ...  We show that we can represent a large environment with a few salient landmarks and that a large percentage of these landmarks is robustly redetectable from different viewpoints.  ...  Visual localization and navigation is often based on landmarks, that means on objects or regions in the environment that serve as reference points for the robot.  ...

Joint Spectral Correspondence for Disparate Image Matching

Mayank Bansal, Kostas Daniilidis
2013 2013 IEEE Conference on Computer Vision and Pattern Recognition  
We show experimental results of our approach on a public dataset of challenging image pairs and demonstrate significant performance improvements over state-of-the-art. * The authors are grateful for support  ...  The lack of local intensity or gradient patterns in these images makes the application of pixellevel descriptors like SIFT infeasible.  ...  Our MSER detector does not output a detection score and so we only present repeatability numbers based on ordering by scale.  ...

Localization accuracy of region detectors

Andreas Haja, Bernd Jahne, Steffen Abraham
2008 2008 IEEE Conference on Computer Vision and Pattern Recognition  
In contrast to existing methods that are based on the descriptor distance of region correspondences, the new measure is pre-computed on each image individually.  ...  Also, it is shown that localization accuracy linearly depends on region scale for some detectors, which may thus be used as a pre-selection criterion for the removal of error-prone regions.  ...  Introduction In this work, five popular region detectors are compared with regard to localization accuracy in position and region shape: the edge-based (EBR) and intensity-based (IBR) region detectors  ...
