• canny gradient pruning in haar detector computed using wrong indices in previous optimisations, fixed
• custom partial selection not computed correctly in haar detector filter, fixed (needs more extensive check)
• the way extra filter inputs were handled has a bug, if same image is used as extra input in more than one filter and image is updated through another filter, it is possible depending on order of application that some filters will get the previous version of the image as input (because it is cached and not resent to save bandwidth) while only the first filter will get the updated (correct) version, fixed
• re-implement, extend and optimise FloodFill, PatternFill as scanline connected_component with seed algorithm
• make FloodFill, PatternFill function also given an exterior border color (i.e match connected component while not exterior border found) instead of only interior color (i.e match connected component while similar interior color found)
• FloodFill in FILTER.MODE.HUE replaces only hue so it can be used to fill/replace a gradient connected region
• fix FILTER.Color.RGB2HSV for gray values (was changed in previous update)

• add initial versions (in progress) of some machine learning algorithms, kmeans, kmedoids, svd, move connected_components algorithm under machinelearning package
• add new util blas (Basic Linear Algebra Subroutines), refactor and re-organise existing utils into core, array, ..

• handle uniformly and more efficiently multiple extra input images in filters, simplify filters' serialize/unserialize methods (there is a bug to be fixed in how the inputs are handled, see api-reference)
• make filters pass generic metaData in apply method instead of just the src image (e.g useful in composite filters to adjust parameters of filters at run-time based on previous filter outputs etc..)
• a number of filters/plugins have been combined or extended to support various modes of operation defined in FILTER.MODE (see examples)
• two new generic filters (which replace multiple plugins, see updated examples) AffineMatrixFilter (i.e linear geometric map filtering) and ColorMapFilter (i.e non-linear color transformation filtering) instead of having multiple filters and plugins with similar functionalities scattered around, plus dynamicaly optimise them, parametrise them and also have GLSL analogs more easily

• have faster convolutions and statistics for grayscale images via FILTER.MODE.GRAY parameter (i.e .setMode(FILTER.MODE.GRAY))
• histogram equalize filter is now one filter with mode parameter (defined in FILTER.MODE) for type of equalisation (i.e MODE.INTENSITY, MODE.GRAY, MODE.RGB)
• add custom selection option tolerance to HaarDetector plugin so it can detect in a region of image instead of whole (useful for combining detectors to detect different feaures consecutively, where one detects in region detected previously..)
