Multi-Biometrics is a useful technique for the identification of a person. A person has many characteristics that help to identify him. Due to the limitations of unimodal biometrics, multimodal biometrics is being used to obtain more precise results. We propose a method for identifying individuals that integrates facial and palmprint modalities, we apply the Gaussian filter for features extraction...Show More
Localization of edges and corner points by fuzzy detectors in images is the main concern of this paper. This paper presents an approach to edge and corner detection based on fuzzy logic. In this approach SUSAN mask is employed to compute USAN area. The histogram of USAN area permits us construct type 1 and type 2 fuzzy membership functions by fuzzifying USAN area computed about every pixel in an i...Show More
A new corner detection algorithm is proposed to get image corners, and then a novel improved partial Hausdorff distance is presented as the similarity measure between the template and images. Finally, a genetic algorithm with the probabilities of crossover and mutation self-adaption based on fuzzy control is used to search the optimum matching quickly. The experimental results show that the matchi...Show More
Car body deformation modeling plays a very important role in crash accident analyses, as well as in safe car body design. The determination of the energy absorbed by the deformation and the corresponding energy equivalent speed can be of key importance; however, their precise determination is a very difficult task. Starting from the results of crash tests, intelligent and soft methods offer a way ...Show More
This paper describes the design of an indoor surveillance system capable of wall following and human detection based on intelligent mobile robot navigation. The wall following is performed based on a differential velocity control using type-2 fuzzy logic for a wheeled mobile robot equipped with IR sensors and sonar sensors, and human detection is performed by a human detection sensor. We have test...Show More
Intravascular ultrasound (IVUS) is a medical imaging system, which uses a specially designed catheter equipped with a small ultrasound probing device at the distal end of the catheter. This system allows the ultrasound technology in visualizing the blood vessels from the inside and is capable of imaging the diseased vessels, measuring length of the plaque, and detecting composition of the plaque a...Show More
In view of the existing situation of manual measurement of garment dimensions, machine vision has been used widely in automatic measurement of garment dimensions. In this paper, adaptive median filter algorithm is adopted to eliminate the garment image noise; a fast fuzzy edge-detection algorithm is used to detect the edge of garment image; and a new corner-detection algorithm based on Freeman cod...Show More
The Artificial Potential Field (APF), reputed for being one of the most prominent algorithm for traversing a path in the shortest distance possible, has a critical disability when confronted by obstacles classified by the state of being under local minima. The said state occurs when the APF algorithm yields an appreciable attractive force between the immediate position of the robot and the goal di...Show More
Corner detection plays an important role in object recognition and motion analysis. In this paper, we propose a hierarchical corner detection framework based on spectral clustering (SC). The framework consists of three stages: contour smoothing, corner cell extraction and corner localization. In the contour smoothing stage, wavelet decomposition is imposed on the raw contour to reduce noise. In th...Show More
Aiming at the rapidity and accuracy of target tracking in multi-rotor low-altitude motion process, the application of moving target detection system in video sequence on multi-rotor platform is proposed. In this study, template matching and feature point detection in visual sensing were used to track image targets. A Kalman filtering, feature point detection and multi-scale Harris angle matching t...Show More
A fuzzy controller is used to control an obstacle avoidance mobile robot. In this classical problem, the aim is to guide a mobile robot along its path to avoid any static obstacles in front of it. Obstacle avoidance in real-time is a mandatory feature for mobile robots in a dynamically unknown environment. The controller presented here uses three sub-controllers. The outputs are summed to produce ...Show More
Currently, not many attempts are made to use neural-fuzzy inference system for recognizing primitive features of an input image.

Common features of digit characters are extracted and converted into vectors. The neural-fuzzy in...Show More
In this work we design, simulate and implement two fuzzy-logic based algorithms for mobile robots: one for obstacle avoidance, and another one with the combined objective of avoiding obstacles and as well as reaching a pre-defined target point in an unknown environment. The hardware used in this project is the National Instruments (NI)'s embedded robotic platform which houses the SBRIO (Single-boa...Show More
International statistics shows that large numbers of road accidents are caused due to driver fatigue. In this paper the authors tried to detect the fatigue of a person who is working under some stressful conditions like Driving. The principle of the proposed system is based on the facial image analysis for warning the driver of fatigue to prevent traffic accidents. The facial images of the driver ...Show More
Seeded Region Growing (SRG) method can be applied to similar or extremely small image regions for avoiding over-segmentation with complex backgrounds. The original SRG is just using the Fuzzy method and combined with Region Growing to have the edge with a tiny region. In this research, SRG can be applied to the Blood vessel in Fundus. A blood vessel in Fundus is placed in the retina. This tiny blo...Show More
The goal of this paper is to present an algorithm for terrain matching, leveraging an existing fuzzy clustering algorithm, and modifying it to its supervised version, in order to apply the algorithm to georegistration and, later on pattern recognition. Georegistration is the process of adjusting one drawing or image to the geographic location of a "known good" reference drawing, image, surface or ...Show More
Driving a car is a complex and potentially risky activity in people's everyday life, and it requires the full involvement of physiological and cognitive resources. Any loss of these resources can cause traffic accidents. For example, drowsy driving affects the ability to adapt, predict and react to unexpected events. A solution to this problem is the adoption of Advanced Driver Assistance Systems ...Show More
Optical Character Recognition finds application in the field of Epigraphy, which is the study of inscriptions. Epigraphers who read ancient inscriptions are nowadays less in number and almost becoming extinct. There is a lot of scope for digitization of these historical records and automated decipherment of the same. An attempt is made for the recognition of text in ancient Kannada script of two d...Show More
We proposed a fast corner detection algorithm based on dual-threshold, which can detect the corners efficiently in real-time for the fuzzy and uneven brightness mineshaft video images. First, the detector recognizes the flat region and corner region according to four pixels in four directions around the detected pixel, and only detects the corner region to reduce the time consuming. Second, the de...Show More

We characterize the problem of detecting edges in images as a fuzzy reasoning problem. The edge detection problem is divided into three stages: filtering, detection, and tracing. Images are filtered by applying fuzzy reasoning based on local pixel characteristics to control the degree of Gaussian smoothing. Filtered images are then subjected to a simple edge detection algorithm which evaluates the...Show More
