Upgrade to v11

The V11 SDK is very similar in structure and architecture to the V10 SDK, so upgrading is straightforward. In most cases, you can simply replace the V10 SDK files with the V11 SDK files and update any references in your project to point to the new version. The following are specific coding changes to be aware of:

1. The Retouching 2.0 correction suite now requires the AI_FACEMESH model, so ensure your project includes the skinsegm.pnn file and loads the AI engine with the appropriate features.
2. The PFCFBPARAM struct has been updated with new Retouching parameters, including Depth & Volume correction fields.
3. The SDK now requires the AVX2 instruction set (AVX1 was required in v10). You'll see an illegal instruction error if your CPU does not support AVX2. If you need to support older CPUs, please contact us.

License keys from previous SDK versions will continue to work with the v11 SDK.

In a bit more detail:

1. An additional AI model is required for the new Retouching 2.0 correction suite: AI_FACEMESH. This is needed to enable the facial mesh detection used by the Retouching 2.0 engine, with code like this:

    unsigned int aifeatures = AI_SCENE_DETECTION | AI_CORRECTIONS | AI_COLOR | AI_FACEMESH;
    int aistatus = PFC_LoadAIEngine(pAiEngine, aifeatures, binPath.c_str());

   or

   int aiStatus = Pfc.LoadAiEngine(
     PFCAIFEATURE.AI_SCENE_DETECTION | 
     PFCAIFEATURE.AI_CORRECTIONS | 
     PFCAIFEATURE.AI_COLOR | 
     PFCAIFEATURE.AI_FACEMESH,
     binPath);

2. AI_Facemesh is provided by the skinsegm.pnn file, so add this file to your project or ensure it is available in the appropriate location for the SDK to load.

3. The list of Retouching parameters in the PFCFBPARAM struct has been updated:

   • added to the struct
     • bDepthVolume - bool to enable Depth & Volume correction
     • iDepthVolume - int specifying the Depth & Volume correction intensity

   And the following fields continue to exist for backwards compatibility, but these corrections are no longer applied:

   • eSmoothType and eSmoothMode - Skin Smoothing type and mode controls
   • bSlim and iSlim - Face Slimming or contouring controls
   • bCatchLight, iCatchLight, and iCatchLightMode - Catch Light controls
   • eSkinToningMode and eSkinToningType - Skin Toning controls
   • bLipSharpen, iLipSharpen, and iLipSharpenType - Lip Sharpening
   • bBlush and iBlush - Blush controls
   • colorSkinToning and colorBlush - Color controls for Skin Toning and Blush
