# 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.

#### Noise removal

```json

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

{% 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 '{

      }'
```

{% tab title="Python client" %}

```python

#### Out of focus blur reduction

We can also make sharper blurry image like this:

```json

     --data '{

      }'
```

{% endtab %}

{% tab title="Python client" %}

```python

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": ["deblur"]}
    api_response = api_instance.rest_api_process_result_post(process_payload)

```

{% endtab %}
{% endtabs %}

<figure><img src="https://2652559519-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F3i5YcUkcXyIsWHIhRO2d%2Fuploads%2FZyirV8KwTgvKRsw24WEY%2Fperfume-678828_1920-blur-sharpened.jpg?alt=media&#x26;token=b7bf6666-6e43-4088-8730-90fdb006d333" alt=""><figcaption></figcaption></figure>

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

Let's check the results on that image:

```json
{
    "enhancements": ["deblur", "denoise"]
}
```

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

curl --request POST \

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": ["deblur", "denoise"]}
    api_response = api_instance.rest_api_process_result_post(process_payload)

```

{% endtab %}

#### 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.
