There are printed artistic documents where text lines of a single page may not be parallel to each other. These text lines may have different orientations or the text lines may be curved shapes. For the optical character recognition (OCR) of these documents, we need to extract such lines properly. In this paper, we propose a novel scheme, mainly based on(More)
—This paper presents the results of the first Challenge of ICDAR 2011 Robust Reading Competition. Challenge 1 is focused on the extraction of text from born-digital images, specifically from images found in Web pages and emails. The challenge was organized in terms of three tasks that look at different stages of the process: text localization, text(More)
The present work describes the development and optimization of a cell-based androgen reporter assay using the Chinese hamster ovarian cell line (CHO K1) in the 96-well format. The recent reports on increasing exposure of humans and wild-life to environmental endocrine disrupting chemicals (ED) prompt the need for high throughput screening systems for such(More)
Automatic separation of text and symbols from graphics in document image is one of the fundamental aims in graphics recognition. In maps, separation of text and symbols from graphics involves many challenges because the text and symbols frequently touch/overlap with graphical components. Sometimes the colors in a single character are gradually distributed(More)
The present study describes the development and optimization of a cell-based reporter assay for the determination of androgen bioactivity levels in human serum samples. Towards this end, human embryonic kidney (HEK) 293 cells were cotransfected with two plasmids, one encoding the mouse mammary tumor virus (MMTV)-driven luciferase reporter gene and the other(More)
Murine embryonic stem cells (mESCs) have the potential to differentiate into almost any type of cell, and hence, represent a useful biological resource for tissue engineering. The differentiation of mESCs into osteoblasts in vitro is usually dampened by simultaneous differentiation of adipocytes. Insulin exerts a profound effect on bone development through(More)
In this paper, we present a scheme towards the segmen-tation of English multi-oriented touching strings into individual characters. When two or more characters touch, they generate a big cavity region at the background portion. Using Convex Hull information, we use these background information to find some initial points to segment a touching string into(More)
Expression of several actin-binding proteins including profilin-1 is up-regulated during capillary morphogenesis of endothelial cells, the biological significance of which remains unknown. Specifically, we hypothesized that profilin-1 is important for endothelial migration and proliferation. In this study, we suppressed profilin-1 expression in human(More)
Currently text line segmentation is an important stage of research in historical document processing. Because of inter-line distance variability and base-line skew variability, line segmentation in unconstrained handwritten document is very difficult. The line segmentation task gets complicated, when overlapping or inter-penetration situation occurs between(More)
