This paper presents a novel stereo matching algorithm that utilizes the disparity variations of each pixel by cost formulation in a cooperative manner to solve several stereo disambiguation problems. A completely novel Stereo Orthogonal Feature-mapping transform (SOFT) has been proposed to compute the local as well as semi-global stereo matching cost that involves the extraction of the color information...
The self-sustained dynamics of the bee population in nature is a result of their hierarchical working culture, efficient organizing skills and unique highly developed foraging ability, which enables them to interact effectively among each other as well as with their environment. In this paper, a novel algorithm utilizing the bee's swarm intelligence, and its heuristics based on quality and quantity...
Purpose Boundary roughness of a pulmonary nodule is an important indication of its malignancy. The irregularity of the shape of a nodule is represented in terms of a few diagnostic characteristics such as spiculation, lobulation, and sphericity. Quantitative characterization of these diagnostic characteristics is essential for designing a content-based image retrieval system and computer-aided...
Noise estimation is a critical component in MRI image retrieval systems. Despite extensive studies, there are several major shortcomings with the existing techniques for noise estimation learning that can significantly affect their application to MRI image diagnosis. This paper focuses on a novel pixel wise fuzzy based noise evaluation that goes beyond the conventional noise estimation approaches...
Most of the image acquisition algorithms neglect the illumination problem like shadows and direction of illumination changes as well the image degradation caused by motion blur, noise introduction in several intermediate process. This paper presents a novel method of high resolution image generation by interpolating local gradient field and subsequent training of LR cluster patches by fuzzy learning...
As the power required to run micro-electronics circuitry is decreasing these days, an untiring attempt of the contemporary researchers has been to find new environmental energy sources that may have the potential to replace the battery usage in wearable subsystems. In this paper the study of an unobtrusive piezoelectric device has been presented that can be integrated within human shoe-sole, thereby...
The study presented here targets the development of a low power hearing aid that helps an individual, with conductive type of deafness, to hear naturally, clearly and intelligibly. It uses a piezoelectric actuator that helps in direct oscillation of the stapes with the arrival of sound wave resulting in sound demonstration much superior to that of conventional hearing aid. The hydraulic amplification...
