Subject: [SoC] GSoC Weekly report 6 (astronomical image processing
I am working on astronomical image processing plug-in for Opticks. Since
I will attend an international conference tomorrow, I have to post my
report a little bit earlier.
In this week, I finish the implementation of two kinds of local
non-linear sharpeners for image enhancement. I create a parameter dialog
for user to select the filter to use, the extreme value operator or
local adaptive sharpening operator. Also the user can select the window
size to apply the filter. The contrast value is used for modify the
contrast effect of local adaptive sharpening. The larger the value, the
larger the contrast.
Also I have tried to test these two methods with astronomical images
like spiral galaxy M101 and Jupiter.
The details of the report can be found at:
Next week I am in the Netherlands for the conference and will return
