Color Filter Arrays (CFA) used by single sensor cameras captures single color information at each pixel location. The process of estimating the missing color samples to reconstruct a full color image is called color filter array interpolation or demosaicing. Demosaicing the CFA images without denoising leads to demosaicing artifacts that will reduce the perceptual quality of the image. This paper...
In this paper, we model the ambient noise with and without ship noise data collected from the shallow waters of the Bay of Bengal. The wind speed and temperature were approximately constant for both the noise data. The ambient noise was collected using hydrophones at a depth of 5m and 15m from the surface, while the ambient noise added with ship noise data was collected using hydrophones at a depth...
The recent trend of proliferation of road accidents and fatalities, calls for a methodology that can appease the burden on the drivers during certain crucial moments, requiring fast response and decision making. This paper expatiates a novel and effective procedure for determining the steering angle required to keep the vehicle in the middle of the lane. The procedure used is divided in multiple stages...
In this paper, we propose a novel approach for detecting the text present in videos and scene images based on the Multiscale Weber's Local Descriptor (MWLD). Given an input video, the shots are identified and the key frames are extracted based on their spatio-temporal relationship. From each key frame, we detect the local region information using WLD with different radius and neighborhood relationship...
Local field potential (LFP) has been of growing interest in interpreting specific motor activities and higherlevel cognitive functions for neurophysiological investigation. LFP denote the neural activity recorded from the ensemble of neurons which carry information in the frequency range of 1–200 Hz. The requirements on the electronics of an amplifier sensor used to measure LFP signals is very stringent,...
