Quarktet Tria Features

Tria Image Processing is much more than deconvolution!

Image Processing

Performs image mathematics with addition, subtraction, multiplication, and division.
Allows the user to apply his/her own image equations to up to four images.
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 common filters: mean, weighted mean, despeckle, sharpen (light, medium, and heavy), edge detect (LaPlace, Sobel horizontal, Sobel vertical), and rank filter.
Apply advanced filters like a selective median filter to remove outlier noise, a signal-dependent rank ordered mean filter that is several steps above the selective median filter, and a symmetric nearest neighbor filter that removes noise while preserving edges.
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
Remove noise floor from image.
Dim objects such as bright stars or sunlight to ensure that they are not saturated in display images
Batch process images in folders, using many 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 with 32-bit floating point precision, 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.
