Re: Wavelet-compressed HRV data

Guy Martin <agm@...>

Hi Ian,

I'm saving them as jpg with a setting of 100. Saving does now take longer but the images are now excellent. I'm using an Athlon 1200 with 512Gb and the processor spends time at 100% so an upgrade is planned in the future as it is my main working machine. I'm not concerned about image size as I only archive interesting features and will copy them to CD.

Cheers, Guy

Are you saving the HRV images as png or jpg. If jpg what setting are you
using. I have increased the jpg setting to 90, but I am still getting
artefacts, although slight improvement. Most noticeable as you say as the
terminator approaches. I am running everything on one Athlon 1200
extremely successfully, but am endeavouring to keep HRV image size
to a reasonable level without too much artefacts/pixellation.

> It has certainly improved picture quality. Animating the terminator now
shows a smooth transition to black with no artifacts or pixellation. The
system appears to cope just as well.
