It is intended that a small robot arm (mitsubishi) be directed by a simple vision system to the centroid of the plantlet. Assistance is required with the vision system: suggestions for a suitable software/hardware configuration for a PC based environment. Comments on experience with the Mitsubishi RV1-MING robot would also be appreciated. thanx.

I am looking for pointers to literature on modeling simultaneous color contrast effects. The application is this: In choropleth maps, each enumeration district (states on a map of the U.S.) is colored to signify some data value for each district. But the appearance of each district is modified by the colors of the states around it, potentially making map reading quite difficult. I want to predict the amount and direction of modification of each color, and then "correct" for the contrast effects by building a display in which the predicted apparent colors signify the data values, rather than the "naive" colors. My initial attempts have dealt with achromatic maps but I hope to work with color. The modeling style of several retinex researchers seems relevant: choropleth maps are much like the set of colored areas in the mondrian images often used in retinex work. Indeed, simultaneous color contrast seems to be the annoying flip side of a color constancy mechanism. If you are aware of any efforts to model (i.e. predict) simultaneous contrast effects, please point me to them. Thanks.

If so, did you have as terrible an experience with it as we have? Thanks, Keith Bartels ------------------------------ From: "John K. Tsotsos" <tsotsos@vis.toronto.edu> Subject: University of Toronto, Research Associate in Vision/Robotics Date: Tue, 8 Jan 1991 13:34:12 -0500 University of Toronto Research Associate in Vision/Robotics The successful applicant must hold a PhD in Computer Science or Electrical Engineering with specialty in areas related to robot vision and must possess a strong research record. Experience with stereo-vision robot heads would be an important asset. Ideal candidates will have broad interests and talents across such areas as biological models of vision and motor control, computational vision and image understanding, attention and active perception, robot navigation, and planning. Applications should be sent by March 15, 1991 to: Professor John K. Tsotsos Department of Computer Science University of Toronto Toronto, Ontario, Canada M5S 1A4 In accordance with Canadian immigration regulations, priority will be given to Canadian citizens and permanent residents of Canada The University of Toronto encourages both women and men to apply for positions. ------------------------------ Date: Tue, 15 Jan 91 14:49:41 +0100 From: ronse@prlb.philips.be Subject: Preprint available: Morphological shape and region description Morphological shape and region description by C. Ronse and B. Macq Philips Research Laboratory Belgium Abstract. A new algorithm for multiscale description of binary digital regions is given. A region is represented by a growing sequence of subsets approximating it; each approximation is obtained from the previous one by addition of the opening by a structuring element chosen in a finite family. The structuring elements vary in size and shape, and are chosen at each step according to two criteria: largest structuring element size and greatest increment in the size of the approximation. The algorithm satisfies meaningful algebraic properties and converges to a final result in a bounded number of steps. It allows also an economical representation of shape in terms of structuring elements, and so it can be applied in binary image coding. If you want a (printed) copy, please send me your SNAIL MAIL (not e-mail) address, including ZIP CODE and COUNTRY (unless Belgium), and the TITLE of the preprint.

To showcase this research, Ablex Publishing is planning a special volume on "Neural Networks in Vision", scheduled for 1992. This volume will be a part of "Progress in Neural Networks", an annual book series reviewing research in modelling, analysis, design and application of neural networks. Authors are invited to submit original manuscripts detailing recent progress in neural networks for vision. The paper should be tutorial in nature, self contained and preferably, but not necessarily, about fifty double spaced pages in length. An abstract and an outline are due by January 31, 1991, the full paper by Feburary 28, 1991. Make submissions to Rakesh Mohan Associate Volume Editor IBM Thomas J.
