STEGANALYSIS OF LSB INSERTION METHOD IN UNCOMMPRESSED IMAGES USING MATLAB
Abstract: In this paper we have explained steganalytic tool to detect presence of the hidden message in LSB steganography. It is the process of hiding secret information in cover image. Here we have used the LSB insertion method using discrete algorithms. Steganographic programs use Least Significant Bit (LSB) embedding as method of choice for message hiding 24-bit, 8-bit color images and grayscale images. It is commonly understood that changes to LSB …

FIBER BRAGG GRATING- For optimal performance in optical systems
Abstract: In this paper FSO link is analyzed for 650nm wavelength operation. Simulation results provide maximal link range of around 2540 meters using visible light red spectrum. The bit rate obtained for optimized link is 10Gbps. The performance of proposed link can also be improved for sustainability of communication channel in various weather conditions and is evaluated on the basic of parameter like BER, Q factor and eye diagram. For θdiv …

2D Interpolation technique for Channel Estimation in OFDM Systems
Abstract: The use of interpolation technique with low estimation error is imperative for estimating the channel impulse response at data subcarriers for pilot assisted channel estimation techniques in the Orthogonal Frequency Division Multiplexing (OFDM) systems. In this paper, a novel interpolation technique based on 2 d interpolation is presented. The proposed interpolation technique is based on minimizing the interpolation error and channel noise inherent in Least Square (LS) estimation. A comparative …

Wheat Grain Quality Analysis Using Image Processing
Abstract: Rice and Wheat are two major staple cereals used globally. In India too, both of these crops are cultivated and consumed in large quantities. In this article, we are demonstrating an image processing approach to segregate bad quality wheat seed grains from the good quality. Wheat is not only the source of carbohydrate, but it also contains protein in ample amounts. The protein content in wheat is higher than that …

GESTURE Controlled Robot using ARDUINO PRO MINI , MATLAB , IP Webcam
Abstract: This system is designed to for the handicapped person to control things in industries so they can get a similar platform i.e. even better than normal person. The gesture control robot observes the gesture of the user and perform a task as per given instruction in Arduino board. A camera on robot captures the gesture and send it to the laptop where MATLAB image processing takes place and afterwards the …
