The aim of this paper is to present a hand gesture recognition approach in static hand posture images. The major steps of the work includes (a) segmentation of hand region from rest of the image, (b) formation of saliency image (c) feature extraction using Gabor filter and Pyramid histogram of oriented gradients (PHOG). The YCbCr color model is used to detect the skin region of the hand, whereas the...
This paper presents a simple and novel approach for de-noising of the Audio Signals i.e. non-stationary signal using statistical distribution function at different sub-band level of coefficients. The performance of wavelets are analysed under various thresholding techniques. Nonstationary signals are continuous in nature consequently we use 1D Discrete Wavelet Transform which gives us a better time-...
In this paper, a simple and robust method has been presented to detect various abnormal activities that can be easily used for elderly monitoring application. The monitoring of elderly persons has become an essential concept in today's world which is moving at a rapid pace for the safety of elders. Due to the fact that some abnormal activities have adverse effects on physical and mental conditions...
In recent technologies, device scaling leads to increase in dynamic power, sub threshold leakage, and degradation of noise margins which are vital obstacles in future generation memory circuits. This paper explores the design of a 6T cell of SRAM. A low power, large SNM 6T cell using conventional MOSFET and DG MOSFET is designed and the results of simulation using ATLAS shows that a 6T cell using...
The objective of this work is to recognize 40 basic hand gestures. The main features used are centroid in the hand, presence of thumb and number of peaks in the hand gesture. The algorithm is based on the shape based features by keeping in the mind that shape of human hand is same for all human beings except in some situations. The hand gestures are captured and stored in the disk. The stored images...
