Hi. May I know how to rotate signature image by using orientation regionprops and then I want to display it at axis ? Below is my code
image1= getimage(handles.axes1)
bw1=imresize(image1,[128 256])
%binarization
bw1=im2double(bw1);
bw1 = im2bw(bw1,0.90);
%thinning
BW3=bwmorph(~bw1,'thin',0.9)
stats=regionprops(BW3,'Orientation','Centroid')
ori=[stats.Orientation]
c=stats.Centroid
x=c(1)+10*cosd(ori)
y=c(2)-10*sind(ori)
line([c(1) x],[c(2) y])
%display result at axes2
axes(handles.axes2)
imshow(BW3)

Try this
meanAngle = mean(ori)
BW3 = imrotate(BW3, -meanAngle);

It rotates the image about the center of the image. If you don't want that, then maybe you can use imtranslate() before imrotate(), or else use the translation and rotation in your own matrix. See Wikipedia
