The main objective of this work is to segment the medical image under various conditions and different backgrounds. Image segmentation is very useful and it improves the results of image analysis. Segmentation done manually is not an easy task also it consume a lots of time. Its accuracy percentage is also very less. So, there is a necessity of developing accurate and efficient algorithms for medical...
MRI-a computer based image processing technique for detecting and diagnosing brain tumor. Segmentation of images in MRI helps us to detect - tumor size, location and shape. There are many techniques of segmentation in image processing. Segmentation techniques are region based, boundary based and threshold based. Threshold technique involves an entropy based algorithmic techniques that are highly useful...
We proposed and analyze numerically an ultra high figure of merit based refractive index sensor in Plasmonic Bragg grating. Structure is simulated by FDTD (Finite difference time domain) method under a PML (perfectly matched layer) absorbing boundary condition. Silver metal is used as metallic part in MIM (Metal insulator metal) waveguide geometry and insulating layer is taken as air. Permittivity...
PID regulators have been famous within professionals and widely accepted for dominant industrial systems where the main objective is the performance. Industrial processes are generally complex, containing interacting multi input multi output (MIMO) controller loops. Operators of industrial processes have a good expertise in PID controller tuning. PID controller can be equipped with predictive property,...
E tendering is a way to publish and bid for a tender online that is so secured that it has reduced the corruption as no one will be aware of the actual facts and figures that other parties must have quoted and uploaded on the network. The tendering process cannot be completed without proper sealing of the quotation envelope. In E-tendering this is done through cyclic redundancy check of the video...
A rectangular micro strip patch antenna is presented in this paper for 915 MHz band applications. These applications include Zig Bee and Bluetooth. The potential of Zig Bee technology is enormous due to its tremendous advantages such as the capability to provide extremely fast data rates at short transmission distances while requiring very low power dissipation. Recently, printed antennas have played...
Converting Navigation to Offline thereby designing it more user-friendly with wider accessibility to a wider range of people is the main motivation behind the work. This paper proposes a Reverse K-Mean Clustering approach that utilizes the concept of k-mean clustering of finding centroids and works inversely as the traditional k-mean to search for the locations in the geographical dataset (map). A...
A π-shape slotted microstrip patch antenna is presented in this paper for 2.4 GHz band applications. These applications include ZigBee and Bluetooth. Recently, these applications have been appreciated and became essential for daily use in industrial and home automation in small areas because of their low power requirement for operation and long battery life. The proposed antenna is constructed on...
QR codes are used to store information in two dimensional grids which can be decoded quickly. The proposed work here deals with Quick response (QR) code extending its encoding and decoding implementation to design a new articulated user authentication and access control mechanism. The work also proposes a new simultaneous registration system for offices and organizations. The proposed system retrieves...
