This paper is focused on the use of a computer aided method for analyzing the drawings of patients' undergoing projective psychological tests. The sketches are drawn on a standard A4 paper placed over a specially designed touch screen. The authors developed the software aimed to automatically both to automatically measure the geometrical characteristics of the designed object and to deliver some additional...
Bilinear interpolation algorithm is broadly applied in digital image processing but its calculation speed is very slow. In order to improve its performance in calculation, this paper proposes a graphic processing unit acceleration-based bilinear interpolation parallel It mainly utilizes Wallis transforming independence among various blocks in bilinear interpolation, which is adaptable to characteristics...
Research in content-based image retrieval today is a lively discipline, expanding in breadth. Discovering new and innovative processes of locating a desired image from an expanding collection of images has been a major area of interest for many professional fields. This has led to the increasing use of a technique called Content Based Image Retrieval which is used to retrieve images based on low-level...
Target reporting plays an important role in firing accuracy test and exercitation of small arms. Since a long time, we have been relying on the traditional manually target reporting, whose disadvantage is big error and low efficiency. We construct a new automatic target reporting system by means of machine vision. It analyses the captured target image with image processing technology, outputs bullet...
This paper presents a motion capture system designed to detect and manage body motion, measuring some motion parameters, and providing a graphical reconstruction of the movement. This system can be used by a doctor to record some target body movements, which a patient can execute remotely at home. Such movements are later analyzed by the doctor who evaluates the report using effective metrics or viewing...
On the basis of image processing, the Chinese character recognition model of non specific people is researched based on hidden Markov model (HMM), and an improved isolated Chinese character recognition model is proposed based on HMM and scale invariant feature transform (SIFT) algorithm. The SIFT algorithm is used to extract the feature points of Chinese character, the SIFT feature point extraction...
Wireless multimedia sensor networks constitute a powerful technology particularly suitable for environmental monitoring. With regard of fire detection and prevention in buildings, fire images acquired by WMSNs provide visual information of fire, which contributes to a more accurate recognition. This paper presents a design scheme of early fire detection system in buildings based on WMSNs. We adopt...
A computer machine vision system that can be used for automatic high-speed fruit sorting and grading is proposed. The objective of the project is to develop the advanced quality control inspection system makes use of distributed network architecture to interface the camera unit to a computer system through GigE LAN environment in a flexible way. The development work activity involves in dynamic capturing...
Internet-based database technologies have already been developed to identify species on the basis of their genotypes and thus most useful for microbe-related disciplines. However, a huge number of microbial species which are estimated to outnumber cells in a host by a factor of ten must need to analyze by an ultra-high-throughput method and therefore a computer-based environment that enables cataloging...
The goal of present work is to demonstrate the possibility to build a fully integrated low cost robot using an artificial vision based localization system known to be utilizable in many environments due to its extreme versatility. To avoid complex algorithms and to bound high hardware resources, simple landmarks are exploited to reduce considerably cost and complexity of recognition system. On this...
The aim of this study is a structured literature review of a computer assisted semen analyzers (CASA) and study the existing methods of finding certain characteristic and parameters of a semen, its density and the morphology of the spermatozoa. The analysis of spermatozoa is an important topic for fertility issues and for assisted reproduction. Spermatozoa analysis plays a vital role in the process...
Ocular Motility is a promising mode of input for human computer interaction. However, we are yet to engineer an application that is cost-effective, robust, user-friendly and far reaching. In this paper we describe an eye-controlled application which will be beneficial to the physically challenged community. Even people who can move only their eyes can use this with ease. This works on principles of...
Quartz wafer inevitably produces various physical defects in the production process. This paper focuses on the quartz wafer dirt defects, and proposes a way for image processing on the quartz wafer by using of computer vision library OpenCV. The proposed method is to find contours of the processed images to judge whether there is dirt or not. Experiments show that this method can well detect the dirt...
Plants play one of the most important roles in our ecosystem. But the rapid decline in the variety of plants is an issue which demands our immediate attention. The first logical step would be the identification of the different plant species by the botanists. Manual identification can often be time consuming and inaccurate. Plants also play a major role in ayurvedic and modern forms of medicine. There...
In this paper, we propose an intelligent alert system that continuously monitors the living quarters of an unattended elderly resident and can automatically issue alerts to family members or helpers when it detects potential accident patterns or suspicious signs in the monitored person's body dynamics. The systems works with absolutely no disturbance to the elderly person's everyday life and no burden...
When capturing images from the microscope imaging system, the images captured are blur and the information in the images is lost due to noise interference in the collection process. The process of microscopy imaging and the algorithm of microscope image denoising based on wavelet transform are discussed in this paper. Spectrum value and noise variance are used to evaluate the denoising effect. The...
The detection of spatial-temporal events is a difficult task in machine vision and it is usually difficult to be handled efficiently with current algorithms and devices. There are many examples in nature, like looming detection or detection of moving objects with given speed and trajectory, which shows that human vision system can solve this extremely difficult task with extremely low power consumption...
The extraction and identification of gene groups with similar expression pattern, plays an important role in the analysis of genes. Clustering and biclustering methods are the primary techniques involved in analyzing gene expresion data which include grouping of genes, classification of genes and classification of a sample. Apart from classical clustering methods, biclustering is being preferred to...
Properties and performances of associative memories, based on Complex-valued Synergetic Computer (CVSC), are explored in this paper. In the proposed CVSC, the state vectors, prototype vectors and order parameters are encoded by complex values. This CVSC is extended from the conventional Synergetic Computer (RVSC) in which the order parameters produce real values in processing real-valued input and...
Surveillance cameras account for a large portion of the security devices market and are used in an increasing number of areas. Recently, surveillance cameras have been evolved into high performance intelligent surveillance camera systems using many image processing algorithms including face and object recognition, image reconstruction, super resolution, and tracking. Most image processing algorithms...
