Structured lighting is a computer vision technique that projects illumination patterns onto the scene to facilitate feature extraction from the captured images. The use of lowcost cameras is avoided not only due to their low image quality but mostly due to the lack of a synchronization mechanism for the illuminators. In this paper we propose a method to synchronize low-cost cameras and illuminators...
Agriculture is the strength of Indian economy. Among various plants, Banana is considered to be one of the most valuable plants. The scientific name of banana is Musa Paradisiacal. It has a life span of about 10–12 months. Banana leaf is to be regularly monitored for presence of disease. They are easily affected by viral disease called Banana Streak Virus. The symptom of the banana streak virus will...
The accuracy of the image is dependent on the quality parameters of camera. The camera parameters is obtained from the target calibration of the test bench in past. Recently, the image processing software can be dealt with the target-free calibration by internal programming. In this research, the images of unmanned aerial vehicle (UAV) are examined by two types of processes, target calibration and...
Processing of a vast number of aerial images from high-resolution digital camera always leads to the use of lengthy hours. This contradicts to the advantage of the use of UAV that could acquire and deliver the data rapidly to highlight the actual condition of the terrain. In previous studies, 1033 images were used covering the size of about seven kilometres square of the study area. During image acquisition...
The rapid development of Internet of Things and the current capabilities of high performance embedded systems have made them more attractive for the replacement of human personnel in hazardous or tedious duties. One such application is for guarding certain areas, such as the entrance of a warehouse for example. The aim of this work is to design an autonomous embedded security system for surveillance...
Pulse discharge in water, through its generation of chemical active species, has many applications such as cleaning water at reservoirs and lakes. In the study of discharge in water, applications and generation mechanisms have been studied in recent years. However, some mechanisms remain unclarified, particularly in the area of high repetition discharges. High repetition discharges result in an interesting...
Number Plate Recognition technique is widely used in identifying vehicle identity across the world where a standard plate size and font are maintained which makes recognition easy. For implementing number plate recognition specifically in India a lot number of issue comes up like hundreds of different forms of fonts being used, size of plate not maintained, five different color number plate, double...
Regional Integrated Border Surveillance System, is a system that is capable to providing a wide range of data and actual informations. This system is very suitable to support efforts to control the border area by the government. Basically this system is the result of the integration between sub-system monitors. In this research activity has built models of Integrated Surveillance Systems Border Region,...
In order to solve the problem of the traditional intelligent mower, which cannot cover the lawn area and operate complexly, a visual, wireless, autonomous mower system via machine vision is designed. Firstly, collect the image information of locale dynamically by the real-time camera which erected on the high bracket, and display on the monitor of PC, then draw a few mowing range or mowing patterns...
This paper has discuss the image processing of aerial photograph acquired from unmanned aerial imagery capturing system (UAiCs) in generating a digital orthophoto and digital elevation model of a small catchment. The purpose of the study is to produce a recent digital elevation model of the study area which comprise of terrain and water bodies particularly in depicting river water level during rainy...
The goal of this study is to make it possible to measure the distribution of the plankton by using an AUV with a digital microscope camera on the nose. Because of the relatively low performance of the storage device in our AUV, the Regions Of Interest (ROIs) that contain focused plankton' images are extracted from a grabbed image in realtime, and only the ROI images are stored in the onboard memory...
We examine the power saving of the demand responsive intelligent bus stop system by the normally-off. Authors designed the demand responsive transport (DRT) bus system for a suburban city. This system uses the intelligent bus stop. Such the bus stop usually consumes a lot of energy, and needs high cost load work for the power supply. However, we revealed frequency of the system use from a practical...
Vehicle accidents are widespread these days. They cause loss of invaluable human lives as well as huge loss of property. An efficient accident avoidance system has been a great need since the invention of motor vehicles. We propose a vehicle accident warning system based on image processing techniques. It uses two criteria for enabling accident warning. These are driver drowsiness and front vehicle...
The increasing variety of functionality in embedded systems leads to more and more complex designs. Even abstraction techniques as applied in ESL design solve this problem only to a certain extend. In this paper we present an approach to improve design understanding of ESL models. Our approach localizes features by comparing simulations on ESL models. Code coverage techniques are used to highlight...
The demand for aquaculture tools have been increasing due to the rising needs for fish. Several factors show the potential requirements for software solutions. For instance, the continual market value growth of fish, government focus on innovative technologies and research on increasing fish production. The Aquatic Tool Kit aims to calculate the total number of larval and juvenile fish through image...
This work presents the development of an optical motion-capture system for 3D gait analysis. The system consists of two video cameras with speed of 25 fps, flash lighter, LED markers, and two PCs and technical computing software, which are used to acquire marker motion attached to human body during walking. The developed system has five module to obtain real coordinate of markers, i.e. pre-processing,...
Next-generation gaming systems enable users to interact with the consoles without the need to touch a game controller. To achieve a more interesting game for two players, we present an interactive boxing game system using motion sensing and analysis. Our system can be described in twofold: (1) Hardware structure, and (2) Software flowchart, which integrate image and video processing techniques for...
In this paper, we propose a ghost artifacts removing algorithm for obtaining artifact-free high dynamic range (HDR) images in the presence of camera movement. Existing HDR methods work on condition that there is no camera movement when acquiring multiple low dynamic range (LDR) images. For overcoming such unrealistic restriction, the proposed algorithm first specifies the target and the source images...
In this paper, an automatic detection system of fence completeness for high-speed railway was proposed. This system uses two cameras installed on CIT (Composited Inspection Train) to shoot the fence on each side individually, and then transmit the images by optic fiber to a computer, which processes the images and recognizes the completeness of the fence automatically. The system will recode any loss...
This paper presents an image segmentation method for feeding or discharging in a jaw crusher based on network edition software ImageJ. The images of crushing material to be broken in a jaw crusher are captured by the CCD camera. Analysis and calculation of boundaries and image segmentation of those images are implemented in the ImageJ based on its some image precessing functions. The results show...
