Hello everybody, I am trying to make the unwrapping of a photo of a cylindrical object (only one side), I applied this code I wrote:
if true % code
I = imread('2258.jpg'); axis onbox onimshow(I)ndims_in = 2;ndims_out = 2;forward_mapping = []f = @(x, unused) arcsin(1/x);inverse_mapping = f;tdata = [];tform = maketform('custom', ndims_in, ndims_out, ... forward_mapping, inverse_mapping, tdata);udata = [-1 1];vdata = [-1 1];xdata = [-1.57 1.57];ydata = [-1 1];I2 = imtransform(I, tform, 'UData', udata, 'VData', vdata, ... 'XData', xdata, 'YData', ydata);subplot(1,2,1)imshow(I)subplot(1,2,2)imshow(I2)end
but I received lots of errors: ??? Error using ==> mldivide Matrix dimensions must agree.
Error in ==> @(x,unused)arcsin(1/x)
Error in ==> maketform>inv_composite at 592 U = feval(t.tdata(i).inverse_fcn, U, t.tdata(i));
Error in ==> tform at 56 X = feval( t.(f.fwd_fcn), U, t );
Error in ==> tforminv at 68 varargout = tform('inv', nargout, varargin{:});
Error in ==> tformarray at 241 M = tforminv(G,T);
Error in ==> imtransform at 275 B = tformarray(args.A, args.tform, args.resampler, tdims_a, tdims_b, …
Where is the error for you? How could I solve it? Thank you a lot, Phalaen
