The offers OCR (Optical Character Recognition) capabilities to its consumers. In Wisej.AI, the utilizes the Wisej.Ext.Tesseract
extension, which incorporates the Tesseract JavaScript OCR component. This component operates directly within the user's browser and is renowned as one of the most effective OCR solutions available.
Currently, the IOCRService
is utilized by the SmartDataEntryAdapter
and the SmartObjectAdapter
when their UseOCR
property is set to true
. If this property is not enabled (default), these adapters leverage the vision capabilities of the AI model in use instead.
You can, of course, replace the default OCR functionality with any OCR solution of your choice. The interface is straightforward to implement, and all methods are asynchronous, enabling you to integrate any OCR service. This includes remote services or AI models with vision capabilities.
The file below demonstrates the internal implementation of the IOCRService
, illustrating how it utilizes Tesseract as a client-side component.
The default implementation of the interface in Wisej.AI is called . This implementation utilizes Wisej.Ext.Tesseract internally to perform Optical Character Recognition (OCR) directly within the user's browser using JavaScript.
You have the flexibility to create your own OCR service by implementing the method. In doing so, you can use any library that meets your requirements. It is important to note that components relying on the IOCRService may provide an option called UseOCR
. This option needs to be set to true. Otherwise, the component will default to leveraging the model's built-in vision capabilities to interpret text from images.
