It is widely accepted that feature extraction is quite possibly the most critical step in computer vision. Typically, feature extraction is performed using a method such as the histogram of oriented gradients. In recent years, a shift has occurred from human to machine learned features, e.g., convolutional neural networks (CNNs) and Evolution-COnstructed (ECO) features. An advantage of our improved...
Recognition of complex language objects is a proposition for human-like perception of the surrounding world by machines. The crucial complication is a high complexity of relationships that may arise in the recognition of these objects. This implies existence of a high variety of approaches for perceived image objects recognition. One of the approaches, to which also this paper is devoted, is based...
In this paper a novel, efficient, and fast-performing vision-based system for traffic flow monitoring is presented. Using standard traffic surveillance cameras and effectively applying simple techniques, the proposed method can produce accurate results on vehicle counting in different challenging situations, such as low-resolution videos, rainy scenes, and situations of stop-and-go traffic. Due to...
With the increase of technological developments, the speed limit of the processors that have emerged has accelerated the reduction of nanotechnological solutions of transistors into atomic dimensions from nanometers. Physical systems in which stochastic computation is critical instead of deterministic computation by taking action from atomic behavior are discussed. For this reason, as an interdisciplinary...
Robots based on vision guidance are very important to the future of vehicle navigation. They have the ability to navigate through a predetermined track and avoid obstacles. They operate remotely with a central computer tracking and guiding them. This allows for communication between robots. This can be used to implement traffic based navigation. Where routes can be recalculated depending on traffic...
In this work an image processing system was developed to identify malaria parasites in thin blood smears and to classify them into one of the four different species of malaria. Many techniques were implemented in the preprocessing stage to enhance the images. In the first part of the system morphological processing is applied to extract the Red Blood Cells (RBC) from blood images. The developed algorithm...
One of the dominant causes of visual impairment worldwide is Cataract. It causes a blurred and foggy vision which can lead to partial or complete loss of eyesight. A protein layer is developed gradually and the lens becomes cloudy over a long period of time which reduces vision and leads to blindness. Early treatment can lessen the difficulties faced by cataract patients and avert visual impairment...
We grew up interacting with the physical objects around us. And there are large number of them that we use everyday. These objects are more fun to use than our computing devices. Taking about objects, another thing that get's attached with objects is gestures; how we manipulate these objects & how we use them in everyday life. These gesture are used to interact with objects as well as to interact...
Groundwater contamination by Arsenic is a huge problem in many countries. In a developing country like Bangladesh, with widespread Arsenic contamination and lack of laboratory facilities, usually field detection kits are preferred to detect arsenic in tubewells. However, these kits produce a significant number of false positives/negatives due to human errors in matching the detection test-strip colors...
Food is the basic need of life. The quality of food is very important factor for proper nourishment of life so that, there is a requirement of assessment of food quality. In this paper, we proposed the system that assesses the food grain quality using image processing. It is proposed to work at ration shop to avoid the distribution of low quality grain. In this system, visual inspection for quality...
We studied the possibility of image processing with the graphical processing units. The time of fast Fourier transform calculated with the graphical processing unit was compared to the one calculated with the central processing unit. The fast Fourier transform algorithm was programmed using the different means. Also the influence of tasks distribution between multiprocessors on calculation speed was...
Eye is the main sensing organ in human body, so it contributes much for user interface. Eye tracking has been widely used in Human Computer Interactions. Real time face image capturing along with eye gaze tracking can provide a means of user input to the computer. Here we combine an efficient method for tracking eye and detecting blink to produce an environment by which physically disabled persons...
The paper presents a prototype for a two way peer to peer communication and advanced human computer interface (HCI). This could be in the form of a wearable ring equipped with laser, infrared and other radio capabilities that enable the human beings communicate with people and other smart devices in a much natural way. The ring ensembles two way peer to peer laser communication, NFC (Near Field Communication)...
White blood cells protect the immune system against viruses and bacteria. Data extraction from white blood cells may cause problems such as loosing form, dimensions and edges. In this study, a complete and automatic method to identify and classify white blood cells using microscopic images has been presented. In the proposed method, in the first step, white blood cells are identified using color space...
Visually Impaired (VI) and blind people suffer from reduced mobility, as they cannot detect the terrain and their environment. They always need assistance and walking support systems in their daily life. Solutions have been proposed many decades ago and are rapidly improving nowadays due to the technology evolution and integration. A large number of assistance aids have been deployed in real life...
Many computer role-playing games that mime a science fiction or fantastic world have a static world map or the map changes under some scripted assumptions that hardly reproduce the dynamic of a play. In this paper I propose a novel algorithm that enables real time terrain calculation even on a very large world map. An algorithm uses approach based on attraction force calculation and uses gradient...
Though several assistive technologies are available for home-based rehabilitation of stroke patients, people are not using the same for several reasons. Lack of technical competence, chance of electrocution is some of such issues. The cables/ wires of different instruments, measuring devises, rehabilitation systems are often the source of infection; causes of electrocution, discomfort and immobility...
In this paper, we present an automated algorithm for detection of blood vessels in 2D-thermographic images for breast cancer screening. Vessel extraction from breast thermal images help in the classification of malignancy as cancer causes increased blood flow at warmer temperatures, additional vessel formation and tortuosity of vessels feeding the cancerous growth. The proposed algorithm uses three...
A welding seam detection and feature point extraction system for robotic arc welding is proposed in this paper. The system consists of a CCD camera, a line structure laser, a narrowband optical filter to overcome the interference from arc light and other light sources, and an embedded computer board for image processing and error calculation. By taking use of optical triangulation measurement method,...
High-speed camera can be implemented into a distributed camera network, which makes the camera network available to various dynamic applications such as observation at high speed and tracking of fast moving objects. This network system can be referred as high-speed distributed smart cameras (H-DSC). In order to construct a H-DSC, accurate synchronization between cameras as well as real-time feature...
