Angular.js. How to count ng-repeat iterations which satisfy the custom filter

Here's my code:

<div ng-show="?" ng-repeat="item in items | notEmpty">


Kb.filter("notEmpty", function(){
return function(input){
var output=[];
for(var i=0;i<input.length;i++){
return output;

I need to show/hide repeated s according the quantity of filtered items in the loop.
What is the best way to do it?

ng-repeat expression allows filtered results to be assigned to a variable. This variable will be accessible from current scope so you can use it in same scope anyway you want:

<p>Number of filtered items: {{filteredItems.length}}</p>

  ng-show="filteredItems.length > 0" 
  ng-repeat="item in filteredItems = (items | notEmpty)"
