ارسال عکس به کنترلر از طریق ajax

سلام
من کلاس زیر را نوشته ام

 public partial class Person

    {

        public int Id { get; set; }

        public string FirstName { get; set; }

        public string LastName { get; set; }

        public byte[] Image { get; set; }

    }

و کنترلر زیر را هم دارم

  [HttpPost]

        [ValidateAntiForgeryToken]

        public ActionResult Create(Person person)

        {

            if (ModelState.IsValid)

            {

                db.People.Add(person);

                db.SaveChanges();

                return RedirectToAction("Index");

            }





            return View(person);

        }

وview زیر را هم دارم

@model Modal5.Models.Person





@{

    ViewBag.Title = "Create";

    Layout = "~/Views/Shared/_Layout.cshtml";

}





<h2>Create</h2>









@using (Html.BeginForm()) 

{

    @Html.AntiForgeryToken()

    

    <div class="form-horizontal">

        <h4>Person</h4>

        <hr />

        @Html.ValidationSummary(true, "", new { @class = "text-danger" })

        <div class="form-group">

            @Html.LabelFor(model => model.FirstName, htmlAttributes: new { @class = "control-label col-md-2" })

            <div class="col-md-10">
