Configure the headers with "Content-Type": undefined and use the FormData API:

  var config = { headers: {
                   "Content-Type": undefined,
                  }
               };

  vm.upload = function() {

    var formData = new $window.FormData();

    formData.append("file-0", vm.files[0]);

    $http.post(url, formData, config).
     then(function(response) {
      vm.result = "SUCCESS";
    }).catch(function(response) {
      vm.result = "ERROR "+response.status;
    });
  };

Normally the AngularJS $http service uses Content-Type: application/json. By setting Content-Type: undefined, the framework will omit the Content-Type header and the browser will use its default content type which is multipart/form-data for FormData objects.

I think you don't use $http the right way.

You can use the headers attribute of the $http service, like this :

$scope.UploadImage = function () { 
  var config = {
    headers: {      
      'Content-Type': 'multipart/form-data',
    }
  };

  $http({
    method: 'POST',
    url: properties.customerUploadImage_path + "/" + checkprofile,
    data: $scope.tempObject,
    config: config,
  }).success(function (response) { 
    console.log('Uploaded');
  });


};

I suggest you to take a look at the documentation.
