EXPAND - expands image set defined on a grid to context of original image IMOUT=EXPAND(IM,LAB) INPUTS IM - image set extracted using sdextract on a grid (step>1) LAB - optional labels to be expanded OUTPUTS IMOUT - image set representing oringinal image size representing pixels expanded from IM DESCRIPTION EXPAND allows us to move from image data set represnting local regions extracted with SDEXTRACT on a grid to the context of its original image. EXAMPLE % Extract raw image content each 5 pixels >> ex=sdextract(im,'region','raw','block',9,'step',5) % Apply a classifier and get decisions >> dec=ex * pclf % Expand places where we detected target class to original context >> imout=expand( ex(dec=='target') ) % Label in these places original high-res image as target >> im( imout ).lab='target' % Example 2: Expand directly all categories in decision object >> imout=expand(ex,dec); % note we provide dec >> im( imout ).lab=imout.lab SEE ALSO SDEXTRACT, SDIMAGE
