接口 ITxtImageSuperResolution

所有超级接口:

ICvBase

public interface ITxtImageSuperResolution
extends ICvBase

Provides the text image super-resolution (TISR) function.

Text image super-resolution can magnify the image that contains text by a factor of 3 and enhance the definition of the text in the image.

This interface provides two process modes. The MODE_IN mode indicates that the SDK directly invokes the TISR function in the caller process. The MODE_OUT mode indicates that the SDK functions as a client to send a calling request to the HUAWEI HiAI Engine, which performs TISR and returns the result to the caller.

This interface also provides two block modes. In synchronous mode, the calling is blocked in the doSuperResolution method until the super-resolution processing is complete. In asynchronous mode, the doSuperResolution method is returned immediately, and the super-resolution processing result is returned to the caller in callback mode.

doSuperResolution

int doSuperResolution(VisionImage image,
                      ImageResult result,
                      VisionCallback<ImageResult> visionCallback)

Performs text image super-resolution on an image and returns the result code.

参数:

image - Indicates an input image.

result - Indicates the image after text image super-resolution in synchronous mode.

visionCallback - Indicates the callback class to use.

• If this parameter is null, doSuperResolution is called synchronously, and the image after super-resolution is output from the result parameter.
• If this parameter is not null, doSuperResolution is called asynchronously, and the result parameter should be null. When the asynchronous call is successful, the image after super-resolution can be obtained from onResult, or an error code is passed from onError.

返回:

Returns HwHiAIResultCode.AIRESULT_SUCCESS if the synchronous call is successful; returns an error code otherwise.

Returns HwHiAIResultCode.AIRESULT_ASYNC_MODE if the asynchronous call is successful; returns an error code if any input parameter is invalid.

setVisionConfiguration

void setVisionConfiguration(TxtImageSuperResolutionConfiguration configuration)

Sets the text image super-resolution parameter.

This method can be used to configure the process invoking mode.

参数:

configuration - Indicates the text image super-resolution parameter, TxtImageSuperResolutionConfiguration.
