私はあなたのコードを見直し、いくつかの変更を行い、現在は動作しています。

if (isset($_FILES['uploadedfile']) && $_POST != "") { 
    $targetPath = 'uploads/' . basename($_FILES['uploadedfile']['name']); 
    $url = 'https://gateway-a.watsonplatform.net/visual-recognition/api/v3/classify?api_key={your_key}&version=2016-05-20'; 
    $post_data = array(
     'file' => 
     '@' . $_FILES['uploadedfile']['tmp_name'] 
     . ';filename=' . $_FILES['uploadedfile']['name'] 
     . ';type=' . $_FILES['uploadedfile']['type'] 
    ); 

    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_URL, $url); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($ch, CURLOPT_POST, 1); 
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data); 
    $headers = array(); 
    $headers[] = "Content-Type: multipart/form-data"; 
    $headers[] = "Accept: application/json"; 
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); 
    $result = curl_exec($ch); 
    if (curl_errno($ch)) { 
     echo 'Error:' . curl_error($ch); 
     die; 
    } 
    var_dump($result, true); 
    die; 
}
