 Tria Features and Functions
Tria Image Processing is much more than deconvolution!
Image Processing
  • Performs image mathematics with addition, subtraction, multiplication, and division
  • Performs sub-pixel image shifts, rotations (all degrees), flip horizontal and vertical, and scaling using either nearest-neighbor, bilinear or bicubic interpolation
  • Convert images  to one of seven formats
  • Applies the following filters: mean, weighted mean, despeckle, sharpen (light, medium, and heavy), edge detect (LaPlace, Sobel horizontal, Sobel vertical), and rank filter
  • Crop images using either coordinates or the mouse
  • Apply Fourier functions such as Fast Fourier Transform, Inverse FFT, extract Magnitude and Phase, Complex Conjugate, and swap quadrants
  • Apply deconvolution using the pseudo-inverse filter, (as effective as iterative techniques, but a lot faster)
  • Apply the SeDDaRA blind deconvolution method, (at least as effective as iterative techniques, and a lot faster)
  • Apply the CARon approximation of the SeDDaRA function, extracting the blur function without a reference image
  • Quickly align (a.k.a register) images for differences in translation, rotation, and scale to sub-pixel accuracy
  • Batch process images in folders, using any of the functions described above
  • Batch Averaging of image stacks
  • Flat-field images to remove background noise and CCD artifacts
  • Clean and center point spread functions, in preparation for deconvolution
  • Create and save reference images for use with SeDDaRA
  • All operations are performed on the image data, and not the 24-bit displayed representation of the image
Image Analysis
  • Apply metrics to compare the results of image deconvolutions, including mean least squares, dynamic signal-to-noise, full-width half maximum comparisons, and Quarktet's own edge response measure
  • Perform spot analysis to determine the size and shape of star and planet images and save results in the measurement log.
  • Measure distances, angles, and aspect ratios using the mouse while saving the results to the measurement log.
  • Superimpose custom grids on the image
  • Perform line-out plots by dragging the mouse across the image
  • View full and Region-of-interest image stats in the status bar
  • Use Tria's Graph window to:
    • display image line-outs
    • quickly see line-out stats
    • click on lines to display image point values
    • save line-out data to text files
    • display image histograms for 256, 512, or 1024 bins
    • quickly jump between line-outs for different images
    • use graph cursors
    • change graph properties
    • display X axis in either X, Y, or interpolated coordinates
    • change plot line width without redrawing line
  • Change pixel scale of the displayed image
  • Split and merge RGB images
Image Display
  • Apply false color representation to grayscale images
  • Use 'easy to find' sliders and settings to change image contrast
  • Contrast settings include ABS (0 to max), MAX (min to max), HIST (10% to 90%) and Manual
  • Use a Region-of-Interest to calculate and adjust contrast settings
  • Use Image Magnifier viewer to see pixels up close
  • Zoom images using with or without interpolation
  • A unique 'Compare' Image Viewer for direct comparison of processed and unprocessed images
  • Create highlights in grayscale images based on image amplitude.

 Convenience

  • Opens and saves 8, 16, and 32-bit floating point TIFF images, 24, 48, and 96-bit RGB TIFF images, 8-bit, 16-bit signed, 16-bit unsigned, and 32-bit grayscale FITS images, 24, 48, and 96-bit RGB FITS images, grayscale and 24-bit RGB bitmap images,  jpeg images, raw data files, and text delimited files
  • Record and save actions (as text) in log files
  • All processing functions produce a new image, preserving the original
  • Set default open files
  • Provides a handy function to rename and renumber images.
  • View Image Header Information for TIF, BMP and FITS images
  • Customize the Control Panel with your most used functions
