BWs=edge(image1,'canny'); se90=strel('line',3,90); se0=strel('line',3,0); BWsdil=imdilate(BWs,[se90 se0]); BWdfill=imfill(BWsdil,'holes'); BWnobord=imclearborder(BWdfill,1); seD=strel('disk',3); BWfinal=imerode(BWnobord, seD); BWfinal=imerode(BWfinal, seD); BWfinal=invertimage(BWfinal); axes(handles.axes1); imshow(BWfinal); imagemorfologi1=BWfinal; gambar=(imagemorfologi1); nama = strcat('image/dilasierosi/dilasi_',as,'.jpg'); imwrite(gambar,nama); end
and the this is a result : (maybe you can download this, if you want to help me ...)
