Describes how spatial region boundaries are handled. The golden rule for spatial region filtering was first enunciated by Leon VanSpeybroeck in 1986: . ... With this in mind, the rules for determining whether a boundary image pixel or table row are assigned to a region are defined below. For image filtering, pixels whose center is inside the boundary are included. ... That is, an row is inside the boundary without regard to its integerized pixel value. ...

... As an experiment, I made some three-color images of Messier 42, more commonly known as the Great Nebula of Orion. ... green enhanced . ... halfsize or fullsize . ... Each image is a ``true color'' composite of three monochromatic images, in which the red, green, and blue intensities each correspond to the intensity of one of the original images. ... The HST image is assembled from different filters than mine: red is Nitrogen [II] at 6583 , green is H-alpha at 6563 , and blue is O [III] at 5007 . ...

Next: A Plea to Up: Some Problems of Practical Previous: Problems of Fourier . I would like to spend the rest of my time showing an example of the kind of dilemma one can get into when doing restorations. In this particular case we were dealing with an FOC ultraviolet image of the center of M31, and a PC V -band image of the same region, scaled, rotated, and aligned. We wanted to take the quotient of the two images, to look for color effects. ... Image A has low , while B has high . ...

... Bojan Nikolic web pages home . ... There are quite a few large astronomical data analysis packages like IRAF and CASA which offer tools for filtering and smoothing of astronomical images. ... In particular I found that importing a FITS file into CASA, doing some smoothing and re-exporting to FITS introduced enough changes to the format of to the structure of the image that I could easily continue analysis of the image outside the CASA package. ...

Next: An example of Up: Classification of Images Previous: Creation of the . The classification process (command CLASSIFY/IMAGE) tags each frame with one or more character strings supplied by the user that classify the image in a unique way and will be stored into columns of the OST. For instance scientific exposures observed in SUSI using the filter number 639 may be described` with the two strings ``SCI" and ``FILT_639". ...

Design improvements continue to be made in the filter developed using mathematical morphology principles for the Infrared Astronomical Satellite ( IRAS ) images.

With an appropriate normalization, the filter curve was applied to each pixel in the image to remove the Galactic cirrus. ...
