Complex steerable pyramid(CSP)

Hi guys.

I tried this CSP to decompose an image. I don't quite understand the output image as shown, anyone mind to explain? Is the output image display the in the Fourier domain? Or spatial domain?

imageA = imread('testimage','jpg');
imshow(imageA);
I=rgb2gray(imageA);
[pyr, pind] = buildSCFpyr(I,3,3);
pyrAmp=abs(pyr);
pyrPh=angle(pyr);
subplot(2,1,1);
imagesc(pyrBand(abs(pyr), pind, 1));
subplot(2,1,2);
imagesc(pyrBand(angle(pyr), pind, 1));

Input Image

Output

I would like to get the phase of the image after decomposed, is taking angle(pry) correct? Do I still need to ifft2?

abs(pyr)

Thanks.
