Digital image processing for pavement distress analyses
free download
Local agencies have to collect distress data of their network system for building and implementing pavement management programs. Data collection for the whole network is expensive, time consuming, and dangerous, if pursued by traditional field surveys
Laser cladding process and image processing
free download
The laser cladding process involves many processing parameters. We present in this paper a low cost system based on two CCD cameras, a standard acquisition card and a Personal Computer which enables the operator to interact with the process and processing The scanning and computerized processing of images had its birth in 1956 at the National Bureau of Standards (NBS, now National Institute of Standards and Technology (NIST)) . Image enhancement algorithms were some of the first to be developed . Half a century Signal and image processing applications require a lot of computing resources. For low- volume applications like in professional electronics applications, FPGA are used in combination with DSP and GPP in order to reach the performances required by the product
A new class of optimal unitary transforms for image processing
free download
Unitary transform image coding systems have been shown to be a successful approach to achieve image data compression. However, block transform image coding systems generate artifacts which degrade low bit-rate coded images. The discrete cosine transform (DCT), forABSTRACT Programmable IC architectures for image processing applications are reviewed. Chip sets that can be used for image and video compression and for traditional image processing systems like computer-vision systems, chip designs that can handle all

free download
The purpose of this study is to measure the size distribution of blasted rock using the digital image processing software Split-Desktop system in order to evaluate the efficiency of blasting operation. Site of study is a limestone quarry producing limestone for cement
Markov random eld models in image processing ,
free download
Markov random eld models have become useful in several areas of image processing . The success of Markov random elds (MRFs) can be attributed to the fact that they give rise to good, exible, stochastic image models. The goal of image modeling is to nd an adequate In this paper, we propose a method dedicated to classification between benign and malignant lesions in Dermatology in the aim to help the clinicians for melanoma diagnosis. The proposed methodology reduces the very numerous informations contained in the

With a quick glance of the front cover, anyone with normal vision can tell you what has happened. Something has fallen into a liquid, perhaps water, and caused a very symmetric and beautiful splash. What seems like such a simple and natural response hides an
Plastimatch-an open source software suite for radiotherapy image processing
free download
Free and open source software is playing an increasing important role throughout society. Free software provides a common economic good by reducing duplicated effort, and advances science by promoting the open exchange of ideas. This paper introduces theSignal processing is the means and methodology of handling, manipulating, and converting signals for the purposes of recording, analysis, transmission, and storage. Signals, particularly in the context of the biomedical field, are recorded for the presentation and often
Special computer architecture for pattern recognition and image processing -An overview
