Function Documentation

affine_transform_2d_double()

function Iout = affine_transform_2d_double	(		Iin,
			M,
			mode,
			ImageSize )

Affine transformation function (Rotation, Translation, Resize) This function transforms a volume with a 3x3 transformation matrix.

Iout=affine_transform_2d_double(Iin,Minv,mode,ImagSize)

inputs, Iin: The input image Minv: The (inverse) 3x3 transformation matrix mode: If 0: linear interpolation and outside pixels set to nearest pixel 1: linear interpolation and outside pixels set to zero (cubic interpolation only support by compiled mex file) 2: cubic interpolation and outsite pixels set to nearest pixel 3: cubic interpolation and outside pixels set to zero 4: nearest interpolation and outsite pixels set to nearest pixel 5: nearest interpolation and outside pixels set to zero (optional) ImageSize: Size of output imgage

output, Iout: The transformed image

example, % Read image I=im2double(imread(lenag2.png)) % Make a transformation matrix M=make_transformation_matrix([2 3],2,[1.0 1.1]); % Transform the image Iout=affine_transform_2d_double(I,M,0) % Show the image figure, imshow(Iout);
