NDVI Phantom 2 with Mobius camera Blue filter - post processed using "FIJ"I software.InfraBlueNDVI. Lut.
I wrote a macro for FIJI to post process the images... from the Mobius into : Tiff or Jpg into the type of Lut that best represented the data information I was after. Each run was producing 200+ images..
The processing time was 1minute 25 seconds. I then loaded the sequence into iMovie and played around with the timelapse. Using the FIJI LUTs was easy... TRY it YOURSELF.
BTW any camera with the IR filter removed / changed will give the same results.
You need the FIJI app. the Macro I wrote allows you to select - on the fly, your own input AND output folder: l have set "type" to jpeg - this works well with Imovie.
Mobius files are prefixed with IMA.. we use this to collect all the original "blue" files. I used an IMAC for this ...
You may need to source the InfraBlueNVDI. lut files (Plus other luts online).. Mine was done ages ago
NDVIBlu2RedWB.lut NDVIBlu2Red.lut NDVI_VGYRM.lut infraBlueNDVI.lut NDVI_VGYRM (1).lut
name the Macro... NDVI.txt...... MACRO TEXT BELOW: just copy and paste into a text file and save it.
adir = getDirectory("");
setBatchMode(true);
run("Image Sequence...", "open=[adir] file=IMA sort use");
mydir = getDirectory("");
run("Split Channels");
run("infraBlueNDVI");
run("Calibration Bar...", "location=[Upper Right] fill=None label=Black number=5 decimal=0 font=12 zoom=2 overlay");
run("Image Sequence... ", "format=JPEG save=[mydir]")
run("Close All");
setBatchMode(false);
Once you have your original "BLUE" files: OPen the Plugins tab: Macros... Run. Then select the macro: select the input folder and files and run.
You should end up with converted files in the Results folder

addendum how to file : sorry about the Clip quality.... NEW clip to follow in due course. I realised the Caiibration Bar was not appearing on the final image outputs.. (although shown on the images in the stack)

Dear FrankA, Greetings from Nepal, I have a mobius actioncam ( Green Blue and Near Infrared ) which is modified to take near infrared spectrum for plant health analysis NDVI...i have attached it (facing vertically downward as shown in attached image) to a drone (DJI Phantom 3 Professional) for aerial mapping and plant health analysis. I took multiple images in time lapse of every 1 second...but the images are very much distorted (due to vibration, fish eye effect, some other distortions ) is there any ways to correct those distortions caused due to fast moving drone? My plan is to use Agisoft Photoscan to stich those multiple images and create an orthomosaic and run NDVI algorithm for plant health analysis.....but i am stuck with these distortions.i saw the photo of your drone, i wanted to ask did you add anything for controlling vibration effect of drone on the camera? I am impressed with your results. suggest me what should i do to get better image acquisition for NDVI calculation.
Thanks in advance Regards, Suman
