I have tried to obtain the images directly from hospital and institutional sources but have been refused, on confidentiality grounds. If anyone knows where I might get these images(ftp sites, etc.) I would truly appreciate it. I am attempting to do a medical imaging project but cannot proceed without test material. Thanks in advance!! Please mail responses to : brian3@garfield.cs.mun.ca [ A few of these images would also be very useful for the Vision List Archive. Especially if the imaging parameters accompany the data. Please contact me if you have this data. phil... ] ------------------------------ Date: Fri, 17 May 91 10:02:08 CDT From: schultz@halley.serc.3m.com (John C. Schultz) Subject: Re: edge location problem > From: ajb@iti.org (Al Boehnlein) > Subject: edge location problem > > I am looking for a technique that will find an edge with sub-pixel > accuracy. The edge is a special type, in that it is generated with Since you know the reason for the "ringing" (diffraction from an edge) why not deconvolve the image with the appropriate kernel (sinc(x)) which should provide an image without ringing and nearly ideally recover the original object. Then use conventional linear estimators for the edge location to sub-pixel precision. Be careful since sub-pixel precision trades off gray level for resolution so you need to be careful with your lighting. ------------------------------ Date: Wed, 22 May 91 11:30:57 +0200 From: skoft@itk.unit.no Subject: VME-based comp. vision system Does anyone have any experience on continous (real-time) computer vision using a VME-rack with CPU,framegrabber and signal proccessor?

Arps, IBM Almaden Research Center; William K. Pratt, Sun Microsystems, Inc. Cochairs: Myron D. Flickner, IBM Almaden Research Center; Robert M. Haralick, University of Washington Important dates: Abstracts due: July 15, 1991 Author notification of acceptance: November 15, 1991 Camera Ready Abstract Due: December 2, 1991 Manuscript due: January 13, 1991 During the past few years there have emerged two important trends in the implementation of image processing systems. First, is the creation of a new generation of image processing chips, which offer an astonishing degree of capability in small packages at relatively low cost. Second, is the development of standards for image processing and interchange. These implementation trends are likely to profoundly affect the design of the next generation of image processing systems. This conference will seek to cover both hardware and software. In the hardware area, surveys will be given on the capabilities and functionalities of programmable and fixed function, VLSI image processing chips that have recently been introduced. The theme of this area will be exploration of how the availability of such chips will affect the design of future image processing systems. In the software area, surveys will be presented on the emerging dejure software standards being developed by the International Standards Organization and the X Consortium, as well as defacto standards such as TIFF for image transport. The theme of this area will be how these software standards will affect the design of image processing systems, with emphasis on the development of associated software development tools and graphical user interfaces. The conference will bring together individuals who are concerned with the implementation of image processing and interchange systems from both hardware and software perspectives. Papers are solicited on the following and related topics: * programmable and fixed function image processing and interchange chips * image processing hardware architectures and systems * image processing and interchange standards * image processing software architectures and systems * image processing software tools and utilities (including compilers, graphical user interfaces, and image data base systems) ------------------------------ Date: Wed, 22 May 91 16:39:53 -0400 From: "Baba Vemuri" <vemuri@scuba.cis.ufl.edu> Subject: SPIE Geometric Methods in Computer Vision GEOMETRIC METHODS IN COMPUTER VISION (Part of SPIE 1991 Symposium on Optical Applied Science and Engineering) Conference Chair: Baba C.
