Resize the image again, this time specifying the interpolation method. This is not applicable to your particular problem, because you are increasing the size of your original image, but if you resize with a scale factor of less than 1, imresize applies an anti-aliasing filter prior to resizing. 'pixels').Combine that with the figure's 'ResizeRcn' to get automatic repositioning of the axis with the image, and the image stays centered and the same size when you resize the figure. 2 Comments. If you specify a scalar, then imresize3 applies the same scale factor to each dimension in the volume. Matlab image rotation-1. If A has more than two dimensions, imresize only resizes the first two dimensions. MATLAB: Using interpolation to replace missing values (NaN) Floating point linear interpolation.

By default, imresize returns an optimized color map, newmap, with the resized indexed image.To return a color map that is the same as the original color map, use the Colormap name-value pair argument. If scale is in the range [0, 1], B is smaller than A.If scale is greater than 1, B is larger than A.By default, imresize uses bicubic interpolation. Cropping image without using imcrop or imresize.
