Lcp management

[demoulinv]

Description

Add Adobe LCP file management.

Features list

• [X] Load a lcp file indicated by the user (cameraInit) and extract geometry and vignetting models corresponding to camera setting (focal length, focus distance and aperture).
• [X] Automatic search of an appropriate lcp file in a database based on camera maker and model (optional) and lens model (cameraInit).
• [X] Apply correction model for geometry and vignetting (imageProcessing).

Implementation remarks

• expat library has been used to read and load a lcp file.
• For geometry correction, only radial models with 3 parameters can be applied. All models made available in Adobe database are like that but using the Adobe LCP creator to generate a model, up to 5 parameters can be used.
• Geometry model parameters are stored using intrinsics.
• Vignetting model parameters are stored as image metadata.
