How to find the detailed Dimensions information of a list

In 5 digital images I have determined the 2d coordinates of detected objects.

The resulting array (list) can be downloaded from here: http://pastebin.com/7bE0CEJ5

array= {{{1, {533.286, 574.643}}, … , {443, {371., 3.5}}}}

array consists of 5 subarrays (for each image one):

Dimensions[array[[1]] = {443, 2}

Dimensions[array[[2]] = {443, 2}

Dimensions[array[[3]] = {444, 2}

Dimensions[array[[4]] = {442, 2}

Dimensions[array[[5]] = {443, 2}

If I try to show the Dimensions of array, I get the number of images:

Dimensions[array] = {5}

How can I get the complete Dimensions information of the list array?

Your subarrays are not all of equal dimensions. In particular subarrays 3 and 4 have a different amount of elements in their first dimension. Dimensions gives dimensions while the dimension is equal at all levels. Once it gets to a level with unequal dimensions it stops.

array = {{{1}, {2}, {3}}, {{1}, {2}}, {{1}, {2}}};

Dimensions@array
(* {3} *)

However, you can Map it across the subarrays to get your result.

Dimensions /@ array
(* {{3, 1}, {2, 1}, {2, 1}} *)

Hope this helps.
