BP_OBIA_Devel.m

% This script calls OBIA_BP_Function in developer mode, meaning it
% operatesz in single, smasll images without processing in blocks.

%BP_OBIA_devel uses new version of classification written for block
%processing, but allows user to implement on small regions w/o block
%processing (for development purposes)

% todo: add geotiffwrite at end insted of .tfw; change bigtiff to tiff
% writer; edit optomizeConn_16 for case of no peak in MasterMetric and
% other scaling issues (incl no bimodal hist...)
% Script to apply block processing to DCS images- for water classification
% modified from DCS_images_4.m
