# Pre-alignment options
#
# Available choices are (however not all are supported by all sessions):
# NONE (Recommended for anything map projected)
# EPIPOLAR (Recommended for Pinhole Sessions)
# HOMOGRAPHY (Recommended for ISIS wide-angle shots)
# AFFINEEPIPOLAR (Recommended for ISIS narrow-angle and DG sessions)
alignment-method affineepipolar
# Intensity Normalization
force-use-entire-range # Use entire input range
# Select a preprocessing filter:
#
# 0 - None
# 1 - Subtracted Mean
# 2 - Laplacian of Gaussian (recommended)
prefilter-mode 2
# Kernel size (1-sigma) for pre-processing
#
# Recommend 1.4 px for Laplacian of Gaussian
# Recommend 25 px for Subtracted Mean

# Integer Correlation / stereo_corr

# Select a cost function to use for initialization:
#
# 0 - absolute difference (fast)
# 1 - squared difference (faster .. but usually bad)
# 2 - normalized cross correlation (recommended)

# Subpixel Refinement / stereo_rfne
################################################################
# Subpixel step: subpixel modes
#
# 0 - disable subpixel correlation (fastest)
# 1 - parabola fitting (draft mode - not as accurate)
# 2 - affine adaptive window, bayes EM weighting (slower, but much more accurate)
# 3 - affine window, (intermediate speed, results similar to bayes EM)
