### Tesseract OCR OSD Configuration and Usage Tesseract supports Orientation and Script Detection (OSD), which can be used to detect the orientation, script, and other layout features of text within an image. To enable this feature specifically with PHP using a wrapper like `TesseractOCR`, one should adjust configurations accordingly. For enabling OSD in Tesseract through PHP: ```php <?php echo (new TesseractOCR('text.png')) ->detectOrientationScriptLanguage(true) // Enable OSD detection. ->run(); ?> ``` The method `detectOrientationScriptLanguage` sets up Tesseract to perform OSD analysis on the input image[^1]. This function call ensures that when processing images containing text, Tesseract will attempt to determine not only what characters are present but also how they're oriented and which writing system is being utilized. When performing OSD operations, it's important to note that accuracy may vary depending upon factors such as image quality or complexity of layouts involved. Users might need to experiment with different settings or preprocessing steps to achieve optimal results from their specific datasets. Additionally, configuring environment variables or command-line options could further refine behavior during recognition tasks involving multiple languages or complex document structures. However, these aspects go beyond basic usage covered here and would require deeper exploration into Tesseract’s capabilities and limitations.
