Blur only part that is not the flower itself. In fact, the entire image is blurred, and foreground is replaced by the original image.
Abin = uint8(rgb2gray(A)>128);% thresholding of image
f_gaussian = fspecial('gaussian',20,4); % gaussian filter
A_gaussian = imfilter(A,f_gaussian,'same');% applying filter. 'same' size of image after filtration.
Abin_rgb = repmat(Abin,[1 1 3]);%replication of binary image to 3 dimensions (to be able to multiply RGB image)
A_selective_blur = Abin_rgb.*A + (1-Abin_rgb).*A_gaussian; %unblurred part + blurred part
imshow(A_selective_blur)
