https://community.intel.com/t5/Intel-Integrated-Performance/how-to-replace-zero-values-in-an-image-with-another-arbitrary/m-p/800368#M3173 Hello, I want to replace zero values in a 32f image with another floating point value. I tried to combineippiCompareC with ippiThreshold function but couldn't succeed. Is there any simple solution for this purpose?

I was just trying to use Threshold_LTVal, Threshold_GTValetc..<DIV><SPAN style="font-family: Verdana, Arial, Helvetica, sans-serif;"><BR /></SPAN><DIV>That will exactly solve the problem.</DIV><DIV></DIV><DIV>Best regards.</DIV></DIV> Thu, 17 Feb 2011 13:28:52 GMT https://community.intel.com/t5/Intel-Integrated-Performance/how-to-replace-zero-values-in-an-image-with-another-arbitrary/m-p/800370#M3175 Kadir_Kirtac 2011-02-17T13:28:52Z
