HDRWaveletTransform - Out of memory message

[Tony Morris]

Hi Juan & Colleagues

PI 1.5.2 on Windows XP with 3Gb memory

I have been trying to process a registered and integrated image (From a Canon 5D2) w4519 h2916 150.803MB

If I apply a HDRWaveletTransform I have no problems, but if I tick the Deringing check box I get the following message:-

Applying large-scale HDRWT deringing routine:   0%
*** Error: Out of memory
Reading swap files...
603.19 MB/s
<* failed *>

If I then untick the Deringing check box all is ok again!

Regards
Tony

Hi Tony,

Unfortunately the HDRWT deringing algorithms require many temporary working images, which eat a lot of memory.

With just 3 GB of RAM, Windows can only assign 2 GB to applications, while the remaining 1 GB is always reserved for the operating system kernel. Of course, an application can never allocate 2 GB, but only a considerably smaller space, due to other applications and operating system services running on the background.

To know more about how much memory you have for PixInsight, please type the following command:

mem

in PixInsight's command line (the white edit line on the Processing Console window) and press Enter. Let me know what this command prints on the console.

Hi Juan

With Firefox running to enter this!

mem
Total physical memory .......   3326.047 MB
Available physical memory ...   2673.563 MB ( 80.38%)
Total paged memory ..........   4096.000 MB
Available paged memory ......   4096.000 MB (100.00%)

Windows reports a little over 3Gb
