CREST Image, the real time, multi-function image processor
|
Japanese page is here
System requirement
- Macintosh with PowerPC (>250MHz recommended)
- MacOS8.0-8.6
- PCI-bus and LG-3 for realtime calculation
Functions
Realtime analysis
The realtime functions are available in the "MultiRoiCapture" mode
(/RealtimeY/MultiRoiCapture). You can capture images from 50 Rois (region of
interest) and calculate centroid, intensity et al... simultaneously.
Menubar is on the right side of the capture screen.
- NewRoi: make a new roi. Grab the roi and move it with mouse.
Active roi is drawn with double-line. Any roi can be activated by
clicking. Size is changed by grabbing the right/bottom corner.
- KillRoi: Delete an active Roi.
- Option : Setting for realtime measurements/captures.
Number of frames : up to 167000
Capture : save image files and results of calculations in
files with the same name except for extention (*.tif, *.txt).
The program records the time each frame captured in microseconds precision.
- Lowth : Toggle lower threshold on/off for centroid calculation.
- Up/Down: Change lower threshold level.
- Size : Change width and height of all Roi. You can hold size by
activating "HoldSize" mode.
- Movie : Clicking "Movie" button makes it ready for captures/meausrements.
Captures/Measurements start by clicking and stop by
command-period.
Known problems in the realtime analysis.
- Captureing tends to fail with more than 300x300-pixels Roi.
- Bad mouse response. You need to hold click more than 1 frame (30ms).
Stack analysis (StackY menu)
- Centroid calculation(StackY/calc/centroid), average
intensity (StackY/calc/average), average intensity of 4
maximum pixels (StackY/calc/Max4), anisotropy (StackY/calc/anisotropy).
- Up to 50 ROIs can be used in the "multiRoi" mode
(StackY/multiRoi or command-B).
XY-coordinates of spots obtained by
Particle analyzer (/Stacks/ParticleAnalyzer: find spots automatically) can be imported.
All functions available in this mode is written in "RoiInfo" window on
the right/bottom corner of your screen.
- Jump to a given frame (StackY/JumpToSlice or command-J).
Misc
- Read uncompressed AVI, Hamamtsu
photonics Image format (File/Open).
