Magento – Remove Duplicate product Images in Magento 2

I have created a script file to delete all the duplicate product images.

Here is the code I used.

<?php
 error_reporting(E_ALL);
 use \Magento\Framework\App\Bootstrap;
 require __DIR__ . '/app/bootstrap.php';
 $bootstrap = Bootstrap::create(BP, $_SERVER);
 $obj = $bootstrap->getObjectManager(); 
 $app_state = $obj->get('\Magento\Framework\App\State');
 $app_state->setAreaCode('global');
 ini_set('memory_limit','10240M');
 ini_set('max_execution_time', 0); 
 set_time_limit(0); 


 $mediaApi = $obj->create('\Magento\Catalog\Model\Product\Gallery\Processor');
 $storeManager = $obj->get('\Magento\Store\Model\StoreManagerInterface');
 $mediaUrl = $storeManager->getStore()->getBaseUrl(\Magento\Framework\UrlInterface::URL_TYPE_MEDIA);
 $directoryList=$obj->get('\Magento\Framework\App\Filesystem\DirectoryList');
 $path = $directoryList->getPath('media'); 
$productCollection=$obj->create('Magento\Catalog\Model\ResourceModel\Product\Collection');
$_products = $productCollection->addAttributeToSelect('*')->load();
$i =0;
$total = count($_products);
$count = 0;
foreach($_products as $_prod)
{
    $_product = $obj->create('Magento\Catalog\Model\Product')->load($_prod->getId());
$_md5_values = array();

$base_image = $_product->getImage();

if($base_image != 'no_selection')
{
    $mediaUrl = $storeManager->getStore()->getBaseUrl(\Magento\Framework\UrlInterface::URL_TYPE_MEDIA);
    $filepath = $path.'/catalog/product' . $base_image ;
    if(file_exists($filepath))
        $_md5_values[] = md5(file_get_contents($filepath));
}
$i ++;
 // echo "\r\n processing product $i of $total ";

 // Loop through product images
 $_images = $_product->getMediaGalleryImages();

 if($_images)
   {
    foreach($_images as $_image)
    {
        //protected base image
        if($_image->getFile() == $base_image)
            continue;
        $filepath = $path.'/catalog/product' .$_image->getFile();
        if(file_exists($filepath))
            $md5 = md5(file_get_contents($filepath));
        else
            continue;

        if( in_array( $md5, $_md5_values ))
        {
            $mediaApi->removeImage($_product, $_image->getFile());

            echo "\r\n removed duplicate image from ".$_product->getSku();
            $count++;
        }
        else 
        {
            $_md5_values[] = $md5;
        }
    }
  }
  $_product->save();
}

Above script removes if same image file exist for a product, then only it will remove it,

In my case if same image imported multiple times for a product, that is created as image.jpg and image_1.jpg.

I need to remove all duplicate images(which are _1,_2 etc) for all the products.

Please correct me in the above script, to remove duplicate image for the product. Thanks
