This paper speaks about a novel method for detection and tracing of optic disc (OD) in retinal fundus images. Detection of diabetic retinopathy (DR), Glaucoma and Edema are the ones in which OD detection finds the meaning and need. The method proposed here introduces a unique concept of fractal analysis in its own way, exploiting the geometric structure of eye called Pixel Based Multi Fractal Analysis...
Advances in computational complexity of the computer have made Computer-Aided Diagnosis a reality. Automation of computer aided diagnosis using advance algorithm helps to solve complex problem in medical imaging. In the frame of Computer-Aided Diagnosis, this paper presents a fast and efficient method for optic disc detection in fundus Images captured from a portable fundus camera. The algorithm uses...
Glaucoma is a disease that affects the eye and can lead to potential blindness. The need to develop an effective detection system is very necessary as the symptoms of Glaucoma may not be apparent in the early stages. Glaucoma is a disease that can affect all age groups and starts with a decreasing field of vision. Diabetic Retinopathy is a disease that causes damage to the retina due to diabetes,...
Functional Near Infrared Spectroscopy (fNIRS) is a technique used to measure blood oxygenation. In this paper, we design and develop an athletic health monitoring system using fNIRS, to monitor muscle oxygenation. The system is built using LEDs and photo detectors (OPT101) for the sensor patch, which are interfaced using the microcontroller, STM32f4 Discovery. Oxygenation values are obtained using...
The present day video coding standards such as MPEG and H.264 are mainly used for broadcast applications, where the encoder is more complex than the decoder. However, for applications such as low power surveillance networks and wireless video cameras, where there is a dearth of hardware at the encoder, the encoder needs to be simpler, but the decoder can be complex. Distributed Video Coding (DVC)...
The underwater study and communication have gained attention due to the military, commercial and biological purpose. The video monitoring of the underwater activity is carried out by video processing node (VPN) which form a sensor network. The VPN must be power efficient and less complex. The video coding standard such as MPEG and H.26X have a computationally more complex encoder for their working...
Development of gas sensors to monitor combustible gases is imperative due to the concern for safety requirements in homes and industries. The liquefied petroleum gas (LPG)/ NH3 is one of extensively used but potentially hazardous gases and its detection is particularly important, because explosion accident may be caused when it leaks out accidentally or by mistake. Most of the commercially available...
A new algorithm for the type II 2-D discrete cosine transform (2D-DCT) using Ramanujan ordered numbers is proposed. Based on the polynomial transform, the 2-D DCT with size N1 × N2, where Ni is a power of 2, can be converted to a series of one dimensional (1-D) DCT's. The proposed algorithm would be completely multiplierless with the evaluation of the cosine angles of the DCT by Ramanujan ordered...
