single channel, 64 bits integer image

mayritnova — Fri, 09 Jan 2009 18:22:23 GMT

I have a single channel, 64 bits integer image and i `d need a simple program to make some basic tests of the ipp image functions (mainly)before to buy.

So im looking for a simple example doing:

Create an array 1000x1000.
Resize to say 600x600 and 1400x1400.
Apply some filters on it FilterMin,FilterMax,threshold,filter median.
Later mirror, rotate 30 degrees.
Corner and border detection.

Any way to get that?

Hello,

We do not have IPP functions you mention which support 64-bit integer images (resize, rotate, filters). Do you need signed 64-bit integer images or unsigned?

Vladimir

Vladimir, signed or unsigned could be Ok .
Also we could use a float but we expect better performanceusing integers and not need to go back to int after the IPP functions.

In fact we need at least 50 bits but no more than that,so anything above this size is OK. Perhaps is`possible to use a combination of 16 bits and several channels but we didn`t see much information of how to do that on the documentation.

Alberto,

youmay submit this as feature request to Intel Premier Support, so it will be considered at the next version planning stage.
