Missing ENVITASKs 1485 1
Started by Deleted User
Hi,
I'm running ENVI 5.2 and IDL 8.4. According to the online documentation I should have access to ENVITasks such as ImageToImageRegistration and GenerateTiePointsByCrossCorrelation. However, ENVI doesn't recognize these and they are not in the task list ( e.TASK_NAMES ). Aren't these available in 5.2
Thanks!

Single Board Linux Box 1481 1
Started by Deleted User
Hello,
I am working on a project for my lab, where we need a small single board pc that can run an IDL script in the runtime environment. Originally, a raspberry pi was to be used, but I was not aware at the time that ARM CPU's had a completely different architecture from the x86 and x86_64 architectures.
I am now looking at a different board. This board has an 64-bit Intel Atom E38xxx series processor clocked at 1.33 GHz and houses 2 GB of ram. I plan to have the board run Ubuntu, Arch Linux, o...

Widget_Button menu item insensitive 1374 1
Started by Deleted User
Hi,
I'm trying to add a new menu item with 3 buttons. For some reason when it is displayed the very first button is insensitive. I've tried to set the sensitivity but it makes no difference.
Here is a cut down version of my procedure.
PRO MyMenu
wTopLevelBase = Widget_Base(/COLUMN, UNAME='wTopLevelBase', Title='Test', MBAR=wMenuBase)
wFileMenu = Widget_Button(wMenuBase, UNAME='wFileMenu', /MENU, VALUE='File')
wExitButton = Widget_Button(wFileMenu, UNAME='wExitButton', VALUE='Close'...

applying partial least squares regression coefficient to hyperspectral image 1394 3

Hello,
I have a 67x67x149 (col, row, band) hyperpsectral image. I have partial least squares regression coefficients that correspond to each band and an intercept. I want to multiply the corresponding coefficients with the corresponding band's spectral data and add the intercept for each pixel. The final product would be a single band image. I have some preliminary code from other application that I was trying to adapt to my purpose which I will paste below. I am thinking the coefficients can be...
