September 2007
release of version 2.1

- added batchSaliency for batch processing of multiple images

maxNormalizeIterative, estimateShape, sepConv2PreserveEnergy
- fixed boundary conditions for 2d convolution to prevent bleeding
  of energy off the edge. This is a critical update!

displayMap
- changed normalization such that empty maps appear black instead of gray


July 2007
release of version 2.0

Replaced license agreement.

guiSaliency, guiLevelParams
- new GUI version of the code

checkImageSize, runSaliency, guiSaliency
- check for too large images, prompt user to confirm downsampling

defaultSaliencyParams, defaultLevelParams, centerSurround, winnerToImgCoords
- made levelParams its own data structure

maxNormalizeLocalMax, defaultSaliencyParams, maxNormalize
- renamed maxNormalizeStd into maxNormalizeLocalMax

plotSalientLocation, defaultSaliencyParams
- introduced VisualizationStyle option

all mex files
- removed all GPL code from these files

Filters.cpp, Filters.h
- removed functions no longer needed

estimateShape.m
- make shape estimation more robust by checking that the attended
  location is actually inside the attended shape (duh!)


November 2006
release of version 1.1

makeFeaturePyramids.m, runSaliency.m, removeColorFeatures.m
- skipping color-relatated features for grayscale images

normalizeImage.m, maxNormalizeStd.m, 
maxNormalizeIterative.m, maxNormalize.m

- added "phases" field to gaborParams
- adjusted the other functions accordingly

estimateShape.m
- added and corrected comments

defaultSaliencyParams.m
- added comment about comparing levels to the iNVT code

contrastModulate.m
