Adding transition effect to a background-image change on a div

I'm changing the background-image of a div using jquery+css like this:

var slide_images = ["http://foodnetwork.sndimg.com/content/dam/images/food/fullset/2014/2/7/1/FNM_030114-Spaghetti-Carbonara-Recipe-h_s4x3.jpg", "http://www.labrasseriefirenze.it/labrasserie/wp-content/uploads/2013/12/spaghetti-carbonara.jpg"];
var slide_count = 0;


$(document).ready(function() {

      setInterval(function() {
          slide_count=++slide_count%slide_images.length;

          $('.slide_photo').css('background-image', 'url(\''+slide_images[slide_count]+'\')');
          }, 4000);

});
.slide_photo {
  position: relative;
  top: 30px;
  width: 100%;
  height: 200px;
  background-image: url('http://foodnetwork.sndimg.com/content/dam/images/food/fullset/2014/2/7/1/FNM_030114-Spaghetti-Carbonara-Recipe-h_s4x3.jpg');
  background-repeat: no-repeat;
  background-position: center center;
  background-size: 100% auto;
  transition: all .2s ease;
}
.slide_photo:hover {
  background-size: 110% auto;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<div class="slide_photo"></div>

The question is: Is it possible to add a fade-in effect or transition to make the change smoother than it is?

How about some css3 animation like this 

.slide_photo{
  -webkit-animation: fade 4s infinite;
  -moz-animation: fade 4s infinite;
  -o-animation: fade 4s infinite;
  animation: fade 4s infinite;
}

.slide_photo {
  position: relative;
  top: 30px;
  width: 100%;
  height: 200px;
  background-image: url('http://foodnetwork.sndimg.com/content/dam/images/food/fullset/2014/2/7/1/FNM_030114-Spaghetti-Carbonara-Recipe-h_s4x3.jpg');
  background-repeat: no-repeat;
  background-position: center center;
  background-size: 100% auto;
  transition: all .2s ease;
  -webkit-animation: fade 4s infinite;
  -moz-animation: fade 4s infinite;
  -o-animation: fade 4s infinite;
  animation: fade 4s infinite;
}
.slide_photo:hover {
  background-size: 110% auto;
}
@-webkit-keyframes fade {
  0% {
    opacity: 0;

  50% {
