Image enhancement is the process of modification of digital images in order to make quality resultant images such that those can be subjected to further manipulation (like further image analysis). There are several ways to implement image enhancement techniques. In this paper, we have studied a number of image enhancement methods consisting of binarization techniques and hybridization of such techniques...
Bangla OCR (Optical Character Recognition) is a long deserving software for Bengali community all over the world. Numerous efforts suggest that due to the inherent complex nature of Bangla alphabet and its word formation process development of high fidelity OCR producing a reasonably acceptable output still remains a challenge. One possible way of improvement is by using post processing of OCR's output;...
In spite of wide use of projection-based features in handwritten character recognition of several languages, its implementation was somewhat scanty in Bangla handwritten character recognition. This paper introduces the usage of projection profile features in recognizing handwritten Bangla basic characters. Alongside it also demonstrates a qualitative and quantitative analysis to visualize the effect...
Common to other developing countries, telemedicine in Bangladesh has also not yet been widely used due to the expensive access to technology and lack of public awareness. In this paper, a simple and affordable web based teleconsultation system is introduced for remote areas where even basic healthcare is a critical issue. A web application has been developed using PHP and MYSQL for creating an asynchronous...
Optical radiation efficiency is the ratio of scattering cross section to extinction cross section. Optical radiation efficiency has been calculated, using classical electrostatics, for spherical nanoparticles of Ag, Au, Cu, Co, Cr, Ni, Pd, Pt, Sn, and Ti. The particle diameter was varied and calculated for the wavelengths in the range of 400–1200nm. The change in radiation efficiency in glass medium...
An improved and efficient method is presented in this paper to achieve a better trade-off between noise removal and edge preservation, thereby detecting the tumor region of MRI brain images automatically. Compass operator has been used in the fourth order Partial Differential Equation (PDE) based denoising technique to preserve the anatomically significant information at the edges. A new morphological...
In this paper, we introduce a web based learning approach for developing teaching practice and students' knowledge in engineering education, which performs knowledge mining from students' web usage data. We develop an intelligent web application using J2EE that consists both classification and clustering models for mining students' learning activities. The classification model uses decision tree for...
This research addresses the map discovery issue for an autonomous robot in an unknown maze. Breadth First Search (BFS) and Depth First Search (DFS) algorithm can be used to do it. Here, we proposed three variants of DFS to discover the map of unknown maze. We implemented Greedy Approach in Path Selection for DFS Based Maze-map Discovery Algorithm which is one of the variants of DFS based approaches...
Cloud computing has introduced an utility computing model which offers an alternative to traditional servers and computing clusters. Due to fault tolerance and scalability feature, Map Reduce distributed data processing architecture has now become the choice for data-intensive analysis in the clouds. Recently Mapruduce is used as a service or for setting up one's own Map reduce cluster. In this paper...
Image denoising and segmentation are the two most challenging fields in medical image processing particularly when it is application specific. The presence of noise not only degrades the visual quality but also immensely affects the accuracies of segmentation which is essential for medical diagnosis process. In this paper, we present an improved approach for denoising and segmentation of 2-D magnetic...
