This is the twenty-first in a series of bibliographies on computer processing of pictorial information, covering primarily items published during 1990. The coverage is restricted almost entirely to a selected set of U.S. or international journals and conference proceedings. No attempt is made to summarize or evaluate the items cited; the purpose is simply to provide a convenient compendium of references, grouped by subject. The references are arranged under the following headings: (A) General references (B) Related topics (C) Applications (D) Architectures (E) Computational techniques (F) Feature extraction, segmentation, image analysis (G) Matching, stereo, time-varying imagery (H) Shape and pattern (I) Color and texture (J) Three-dimensional scene analysis Letter/number codes in the text (A.1, etc.) correspond to sections of the bibliography. [ This very fine (electronic) reference source is provided courtesy of Dr. Azriel Rosenfeld at the Univeristy of Maryland. Thanks to Joe Sanjour for making this electronic form available to us. We are currently working to see if we can convert the 1990 format into a BiBtex format that may be of more use to many of you. phil... ] ------------------------------ Date: Fri, 31 May 1991 06:28:52 GMT From: uh311ae@sunmanager.lrz-muenchen.de (Henrik Klagges) Organization: Technische Universitaet Muenchen, Germany Subject: Re: 3-D manipulation programs needed!!! I think you should look into the Device Independent Graphics Library (DIGL). It is a machine independent (ie, runs on PC, Mac, Sun, HP, ...) implementation of a very reasonable subsystem of the Silicon Graphics GL library. This library is very nice to program and especially does all the work for you: - it does orthographic or perspective viewing transformations from 3D -> 2D - it does all the rotating and scaling with one 4x4 matrix - it does shading, graphics context save (pushmatrix, popmatrix) etc. It is available from godzilla.cgl.rmit.oz.au (131.170.14.2) via aftp.

To be able to derive coordinates for a robot to grab the objects I need to fit surfaces to the 3-D data. So I am looking for algorithms, literature (survey papers) and software (preferably in C) to interpolate or fit surfaces to 3-D data. My major concern is not accuracy but speed. Thanks in advance Peter Schaeren schaeren@st.ife.ethz.ch ------------------------------ Date: 3 Jun 91 06:39:45 GMT From: rwang <rwang@jarthur.Claremont.edu> Organization: Harvey Mudd College, Claremont, CA Subject: reconstructing binary patterns from projections I am puzzled by the problem of reconstruction of a 1-0 matrix from its row-sum vector and column-sum vector, in other words, recovery a 2D binary pattern from two orthogonal projections. I know Shi_Kuo Chang, et al developed some algorithm to find one of the many possible binary patterns (The reconstruction of binary patterns from their projections" (Communication of the ACM, vol. 14, no. 1, Jan., 1971). But this algorithm does not satisfy my requirement that the reconstructed pattern be SIMPLY CONNECTED, i.e., a connected blob without holes. Alos, in his book "Combinatorial Mathematics", Herbert John Ryser dedicated chapter 6 to "Matrices of aeros and ones". But he didn't discuss any algorithm to actually reconstruct the binary patterns. I would really appreciate it if some one can enlighten me on this problem. Please send me email to: "rwang@echmc.claremont.edu" or "rwang@jarthur.claremont.edu". I am having some trouble accessing the usenet news groups. Thank you in advance! ------------------------------ Date: 30 May 91 15:13 -0700 From: Yggy King <yking@cs.ubc.ca> Subject: References wanted on oriented filtering Hi everyone, I'm looking for references on applications of oriented filtering techniques in vision. Such methods utilize banks of filters at various orientations and spatial frequencies, and include such mathematical models as Gabor filters, difference of offset Gaussians, difference of offset differences of Gaussians, etc. I'm aware of a relatively large body of work on using such filters for texture analysis (e.g. Malik & Perona, Bovik, etc) and am more interested in other potential applications, such as modeling of early stages of biological processing, edge detection, etc. Please email ... I will summarize and post if appropriate. thanks in advance. ------------------------------ Date: Mon, 3 Jun 91 14:07:02 DST From: karit@spine.hut.fi (Kari Torkkola) Subject: Research positions in speech and image processing RESEARCH POSITIONS AVAILABLE The newly created "Institut Dalle Molle d'Intelligence Arti- ficielle Perceptive" (IDIAP) in Martigny Switzerland seeks to hire qualified researchers in the areas of speech recognition and image manipulation. Candidates should be able to conduct in- dependent research in a UNIX environment on the basis of solid theoretical and applied knowledge. Salaries will be aligned with those offered by the Swiss government for equivalent positions. Laboratories are now being established in the newly renovated building that houses the Institute, and international network connections will soon be in place. Researchers are expected to begin activity during the academic year 1991-1992. IDIAP is the third institute of artificial intelligence sup- ported by the Dalle Molle Foundation, the others being ISSCO (at- tached to the University of Geneva) and IDSIA (situated in Lu- gano). The new institute will maintain close contact with these latter centers as well as with the Polytechnical School of Lausanne and the University of Geneva. To apply for a research position at IDIAP, please send a curriculum vita and technical reports to: Daniel Osherson, Directeur IDIAP Case Postale 609 CH-1920 Martigny Switzerland For further information by e-mail, contact: osherson@disuns2.epfl.ch ------------------------------ End of VISION-LIST digest 10.26 ************************
