If I do level 1 decompose the image using swt2 command in matlab it give 4 output. Approximate A, Vertical V, Horizontal H, Diogonal D coefficients. which of them is the highest fequecy and lowest frequency. In SWT decomposition Upper right subband is HH and lower left subband is LL. I am confused.

'swt2' does not return the highest frequency or the lowest frequency. it returns approximation coefficients A and the horizontal, vertical, and diagonal detail coefficients H, V, and D respectively.
Refer to the documentation mentioned below to further understand about the coefficients .
