MicroObservatory Image 2.3:

  • Works on both Macintosh and Windows platforms
  • Opens and saves GIF and FITS files

Basic Image Processing:

  • Optimize an image's brightness/contrast automatically, by either linear or logarithmic scaling
  • Colorize images using several false color tables
  • Invert an image's color table
  • Increase image contrast and detail using "sharpen" filter
  • Reduce the noise in an image
  • Manipulate full screen magnification
  • Show image information for individual pixels by cursor placement

Advanced Image Processing:

  • Perform mathematical operations between two images
  • Perform an integer arithmetic operation to an image
  • Shift an image relative to another image
  • Manipulate an image stack that allows you to create RGB images or animated GIF files
  • Crop portions of an image or image stack when an area is selected with the rectangle tool
  • Calculate brightness levels and image statistics of an area is selected with the rectangle or circle tool
  • Show intensity histograms of the image data
  • Display the header of a FITS image
  • Place text or graphic lines on an 8-bit GIF file in order to annotate the image

Ease of Use:

  • Drag and Drop — you can drag images, files and links onto MicroObservatory Image to open them

Your feedback is appreciated.

Please notify me when a new version of MicroObservatory is released.

Thanks to Wayne Rasband, the author of ImageJ, for color tables and MedianCut code, as well as look-and-feel ideas.
