# How to Read Barcodes from Images with Textures

In some scenes, the background of images may appear textured, such as a patterned background, screen stripes, etc. As shown below, the barcode background has an odd texture due to the computer screen it is being displayed on.

<div align="center">
   <p><img src="assets/read-barcodes-with-texture/texture-image-sample.png" alt="Sample barcode image with texture" width="50%" /></p>
   <p>Figure 1 – Sample barcode image with texture</p>
</div>

This may extend the barcode localization time or even lead to localization errors. The texture detection feature of Dynamsoft Barcode Reader (DBR) works on images with textured backgrounds. The following two images demonstrate the binarized images used for localization without and with texture detection enabled:

<div align="center">
   <p><img src="assets/read-barcodes-with-texture/binary-before-texture-detect.png" alt="Sample barcode image with texture" width="50%"/></p>
   <p>Figure 2 – Binarized image without texture detection enabled</p>
</div>

<div align="center">
   <p><img src="assets/read-barcodes-with-texture/binary-after-texture-detect.png" alt="Sample barcode image with texture" width="50%"/></p>
   <p>Figure 3 – Binarized image with texture detection enabled</p>
</div>

As we can see, the binarized image with texture detection enabled is much better. Now we will demonstrate how to configure the parameter [`TextureDetectionModes`](/capture-vision/docs/core/parameters/reference/image-parameter/texture-detection-modes.html) to enable texture detection.

## Example

Below is an example illustrating how to configure the parameter `TextureDetectionModes`.

* Update parameter `TextureDetectionModes` in your JSON template

    ```json
    {
        "CaptureVisionTemplates": [
            {
                "Name": "CV_0",
                "ImageROIProcessingNameArray": ["TA_0" ]
            }       
        ],
        "TargetROIDefOptions" : [
            {
                "Name": "TA_0",
                "TaskSettingNameArray": [ "BR_0" ]
            }
        ],
        "BarcodeReaderTaskSettingOptions": [
            {
                "Name" : "BR_0",
                "SectionArray": [
                    {
                        "Section": "ST_REGION_PREDETECTION",
                        "ImageParameterName": "IP_0"
                    },
                    {
                        "Section": "ST_BARCODE_LOCALIZATION",
                        "ImageParameterName": "IP_0"
                    },
                    {
                        "Section": "ST_BARCODE_DECODING",
                        "ImageParameterName": "IP_0"
                    }
                ]
            }
        ],
        "ImageParameterOptions": [
            {
                "Name": "IP_0",
                "ApplicableStages":[
                    { 
                        "Stage": "SST_DETECT_TEXTURE",
                        "TextureDetectionModes": [
                            {
                                "Mode": "TDM_GENERAL_WIDTH_CONCENTRATION",
                                "Sensitivity": 5
                            }
                        ]
                    },
                    { 
                        "Stage": "SST_REMOVE_TEXTURE_FROM_GRAYSCALE" 
                    }
                ]
            }
        ]
    }
    ```

* Apply the above settings following the article [Use Templates for Configuring Parameters](https://www.dynamsoft.com/barcode-reader/docs/core/programming/features/use-runtimesettings-or-templates.md#json-template).
