Can I apply griddedinterpolant to a binary image to resize it back? What I want to achieve. Below. Error: Invalid arguments specified in evaluating the interpolant.

F1 = griddedInterpolant(double(G));  %G is binary
xq = (0:6/5:sx)';
yq = (0:6/5:sy)';
zq = (1:sz)';
vq1 = uint8(F1({xq,yq,zq}));
figure(2)
imshow(vq1)

yes you can

A = imread('image1.jpg');
imshow(A);
F = griddedInterpolant(double(A));% create interpolation
[sx,sy,sz] = size(A);
xq = (0:3/6:sx)';
yq = (0:3/6:sy)';
vq = uint8(F({xq,yq})); %change to two argument to avoid error in grayscale or binary image

imshow(vq)
