# Denoise and sharpen

Image can be enhanced in few ways, it can be denoised and it can be sharpened (deblurred).

Version of model for denoise or deblur can be parametrized.

There are two models: v1 and v2. v2 which is newer, handles better heavily blurry and noisy pictures. By default v1 is used.

It is not recommended to use that for good quality pictures though.

```json
"denoise_parameters": {
    "type": "v2"
}
```

```json
"deblur_parameters": {
    "type": "v2"
}
```

Let's check some examples.

#### Out of focus blur reduction

We can also make sharper blurry image like this:

    api_instance = deep_image_ai_client.DefaultApi(api_client)
    process_payload = {"url": "https://deep-image.ai/api-example.jpg", "enhancements": ["deblur"]}
    api_response = api_instance.rest_api_process_result_post(process_payload)

```

{% endtab %}
{% endtabs %}

&#x20;Those two options can be specified together.

Let's check the results on that image:

#### Cleaning the image

Image can also be "cleaned" from artifacts and previously poorly upscaled image.

```json
"enhancements": ["clean"]
```

{% tabs %}
{% tab title="Curl" %}

```
curl --request POST \
     --url https://deep-image.ai/rest_api/process_result \
     --header 'content-type: application/json' \
     --header 'x-api-key: API_KEY' \
     --data '{
         "url": "https://deep-image.ai/api-example.png",
         "enhancements": ["clean"]
      }'
```

{% endtab %}

{% tab title="Python client" %}

```python
import os

import deep_image_ai_client

configuration = deep_image_ai_client.Configuration(
    host="https://deep-image.ai"
)

configuration.api_key['ApiKeyAuth'] = os.environ["API_KEY"]

with deep_image_ai_client.ApiClient(configuration) as api_client:
    api_instance = deep_image_ai_client.DefaultApi(api_client)
    process_payload = {"url": "https://deep-image.ai/api-example.jpg", "enhancements": ["clean"]}
    api_response = api_instance.rest_api_process_result_post(process_payload)

```

{% endtab %}
{% endtabs %}

Resolution of the image remains the same but image should be in better quality.
