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
