# Data
# <markdowncell>
# **In the field, winter of 2011 - 2012 :**
#
# - Daily study area monitoring for deaths
# - 143 liver samples collected within a day of death
# <markdowncell>
# **In the lab :**
#
# - Sectioning after paraffin treatment
# - H&E staining of about 1000 slides
# <markdowncell>
# **Analysis :**
#
# - Pathology standard : semi-quantitative scoring
# - Image processing
# <headingcell level=3>
# The Field ©
# <markdowncell>
# Sweat-and-blood-collected in cold, cold Scotland.
# <markdowncell>
# Eight physical measurements :
# - Age at death
# - Weight
# - Sex
# - Limb length
# - Environmental "stress"
# <headingcell level=3>
# Clinical Pathology
# <markdowncell>
# Operator-driven visual analysis of 98 slides under microscopy.
# <markdowncell>
# Eleven discrete and continuous measures :
#
# - Inflammation
# - Necrosis
# - Apoptosis
# - Hyperplasia
# - Fibrosis
# - Hepatitis
# <headingcell level=3>
# Image Processing
# <markdowncell>
# Automated analysis of 4430 images of slides representing 143 sheep.
# <markdowncell>
# Seven structural and textural measures with varying levels of biological interpretation :
#
# - Inflammation
# - Hyperplasia / tissue density
# - Best-guess proxies for "generic degeneration"

# Image Processing

# The Challenge
# <markdowncell>
# **Information extraction must be**
# - automagical - no operator input
# - reasonably quick - restricted computing time
# - robust - invariant to slicing, staining, field-related variation
# - unbiased - same algorithms for everyone

# Structural and Textural Measures
# <markdowncell>
# - characteristic **scale** of sinusoid widths
# - **directional** amplitude of preferred sinusoid alignment
# - **tissue to sinusoid** ratio
# - **count** of inflammatory foci per image
# - **mean size** of inflammatory foci per image
# - information **entropy** of sinusoid distribution
# - **lacunarity** ( clustering ) of sinusoids

# Conclusions
# <markdowncell>
# - our image measures capture **relevant** and **useful** information
# - a number of correlations can be **explained** biologically
# - underlying **structure** in the data needs thought
# - still no **map** from image or histological measures to condition of individual
# <headingcell level=2>
# Future directions
# <headingcell level=3>
# Further exploration of the dataset
# <markdowncell>
# - 145 sheep ( 89 females )
# - 12 age classes
# - potential redundancy in various measures
# <markdowncell>
# - 4460 entries across 27 variables
# - 3330 with full image and histological information
# - 1196 for which **complete** information is available
# <headingcell level=3>
# More data
# <markdowncell>
# - nutritional information
# - immunity data
# <headingcell level=3>
# Narrow-field images
# <markdowncell>
# - 12536 images
# - spatial distribution of nuclei
