Enhancement of mammographic features by optimal adaptive neighborhood image processing
free download

X-ray mammography is the only breast cancer detection technique presently available with proven efficacy. Mammographic de-tection of early breast cancer requires optimal radiological or image processing techniques. We present an image processing approachAlthough not designed with image processing specifically in mind, the Staran parallel processor has had a significant impact on that application area. The machine is full programmable, yet when applied to image processing it has demonstrated speeds usually ABSTRACT The author studies a class of VLSI organizations with optical interconnects for fast solutions to several image processing tasks. The organization and operation of these architectures are based on a generic model called OMC, which is used to understand the

Special computer architecture for pattern recognition and image processing -An overview
free download

It has been recognized for a long time that a conventional sequential processor is inefficient for operations on pictorial data where relatively simple operations need to be performed on a large number of data elements (pixels). Though many parallel processing architectures for ABSTRACT 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 allImage processing puts heavy demands on computational speed and storage space. The PICAP system of Linkoping University has been designed to meet these demands in an interactive image processing environment, utilizing state-of-the-art hardware and software

Flexible architectures for morphological image processing and analysis

Texture is an important feature which can be used in the interpretation of remotely sensed imagery. This paper presents examples of the application of a new approach to the textural filtering and enhancing of digital images. Satisfactory results are obtained in processing

Human vision models for perceptually optimized image processing a review
free download

By taking into account the properties and limitations of the human visual system (HVS), images can be more efficiently compressed, colors more accurately reproduced, prints better rendered, to mention a few major advantages. To achieve these goals it is necessary to

Image processing using one-dimensional processor arrays
free download

Image processing (IP) is an ideal candidate for specialized architectures because of the sheer volume of data, the natural parallelism of IP algorithms, and the high demandfor IP solutions. The continually increasing circuit density of very large scale integration (VLSI)

Faster graph-theoretic image processing via small-world and quadtree topologies
free download

Numerical methods associated with graph-theoretic image processing algorithms often reduce to the solution of a large linear system. We show here that choosing a topology that yields a small graph diameter can greatly speed up the numerical solution. As a proof of

Theoretical Analysis of Winsoring Smoothers and Their Applications to Image Processing
free download

The Winsorizing smoother (W smoother), which is a center weighted median (CWM) filter giving more weight only to the central value of each window, is studied. This filter can preserve image details while suppressing additive white and/or impulsivetype noise.
