(Up to the [wiki:IPP_for_PS1 IPP for PS1])

This page compares results from several versions of the ppSub DUAL convolution process.

Each page shows the input images, the difference image, the convolved image (for the smaller input image in general), and the convolution kernel pair.  

 * [wiki:ppSub_Modifications_20100918 Modifications as of 2010.09.18] : These use penalty of 4e-6, and are from branches/eam_branches/ipp-20100823, r29224)

 * [wiki:ppSub_Modifications_20100823 Modifications as of 2010.08.23] : These correct the normalization (better apertures) and use different penalties for A and B. Code is from tags/ipp-20100823, r29167)

 * [wiki:ppSub_Modifications_20100701 Modifications as of 2010.07.01] : These use the algorithm from the start of demo month, tags/ipp-20100701, r28945)

 * [wiki:ppSub_Modifications_20100918.v0 Modifications as of 2010.09.18, v0] : These use penalty of 5e-7, and are from branches/eam_branches/ipp-20100823, r29224)

 * [wiki:ppSub_Modifications_20100918.v1 Modifications as of 2010.09.18, v1] : These use penalty of 1e-6, and are from branches/eam_branches/ipp-20100823, r29224)

 * [wiki:ppSub_Modifications_20100918.v2 Modifications as of 2010.09.18, v2] : These use penalty of 2e-6, and are from branches/eam_branches/ipp-20100823, r29224)
