So I'll type it in (it's going to be part of my thesis) and send it to vision list. Expected date of arrival: March 6. This week and next week are way too busy.

He was using some terribly inefficient algorithm to find the area, centroid, corners, etc., of an object. This algorithm was taking 11 seconds (a uVAX using C)! I suggested a quick paint/fill algorithm with some modifications as a better way to obtain these statistics. I'm looking for an efficient algorithm that will fill a solid object or an outlined object (similar to how graphics editors do the "paint-can" effect). Can anyone give me some pseudo-code or point me to an appropriate reference guide? -Cris [ How about Foley and van Dam? pk ] ------------------------------ Date: Tue, 21 Feb 89 14:15:34 +0100 From: prlb2!ronse@uunet.UU.NET (Christian Ronse) Subject: report alert: mathematical morphology, pt. 2 The following report is available. Simply send an e-mail message to one of the two authors, with your postal mail address. NB: Part I was distributed last summer. The Algebraic Basis of Mathematical Morphology; Part II: Openings and Closings C. Ronse (ronse@prlb2.uucp), Philips Research Laboratory Brussels H. Heijmans (henkh@mcvax.uucp), Centre for Mathematics and Computer Science ABSTRACT: This paper is the sequel to a previous paper (Part I) where we have introduced and investigated an abstract algebraic framework for mathematical morphology. The main assumption is that the object space is a complete lattice. Of interest are all (increasing) operators which are invariant under a given abelian group of automorphisms on the lattice. In Part I we have been mainly concerned with the basic operations dilation and erosion. In this paper we will concentrate on openings and closings, which are very special classes of idempotent operators. Much attention is given to specific methods for building openings and closings. Some examples illustrate the abstract theory. AMS 1980 Mathematics Subject Classification: 68U10, 68T10, 06A15, 06A23.

Despite the vigor of research in vision over the past two decades, questions remain about the nature of three di- mensional representations and the use of those representations for recognition and action. What information is gathered? How is it integrated and structured? How is the information used in higher level perceptual tasks? This conference will bring togeth- er nineteen prominent scientists to address these questions from neurophysiological, psychological, and computational perspec- tives. The conference is sponsored by the Air Force Office of Scientific Research and the University of Minnesota College of Liberal Arts in cooperation with the Departments of Psychology, Computer Science, Electrical Engineering, Child Development, and the Center for Research in Learning, Perception, and Cognition. Registration: ------------- The conference fee is $30 ($15 for current students). This fee includes program materials, refreshments, and Wednesday's recep- tion. Conference enrollment is limited, so early registration is recommended. Accommodations: --------------- A block of rooms has been reserved at the Radisson University Hotel. Rates are $68 (plus tax) for double or single occupancy. To make reservations, contact the hotel at (612) 379-8888 and refer to the program title to obtain these special rates. Reser- vations must be made by April 9.

Summary: X11R3 for A/UX is Apple product Organization: Apple Computer Inc, Cupertino, CA Apple will ship its X11R3 product for A/UX in March (1989). The server will support 1-bit and 8-bit deep frame buffers, multiple screens, backing store and save unders. The graphics code has undergone substantial optimization. X11R3 will run on both A/UX 1.0 and A/UX 1.1, however A/UX 1.0 allows just a single monochrome screen. Apple has contributed sources for a single screen, monochrome server to the MIT X Consortium. These appear on the X11R3 distribution which has been publicly available since October. comp.windows.x regularly announces ftp (and other) sites where this distribution may be obtained.
