Practical methods to solve the problem of low OCR recognition rate of fuzzy pictures
When using ImageTranslate to process blurry images, the following steps can be taken to improve the recognition accuracy:
- preprocessing::
- Stabilization when shooting with a cell phone or camera, the use of a stand is recommended
- Make sure there is enough light to avoid shadows obscuring the text
- Keep the lens parallel to the text to reduce distortion
- Post-processing techniques::
- Adjust contrast (50-100%) and sharpness (100-150%) using tools such as Photoshop
- Try grayscale processing to enhance text edges
- Such as documents such as pictures, can be converted to PDF and then screenshot processing
- Optimization solutions in ImageTranslate::
- Selecting the "Auto-detect" source language function
- If recognized incorrectly, manually switch to a more compatible language option
- Make full use of the editing function to correct misrecognized characters
Note: Handwriting is recommended to be converted to print before processing, and complex background images can be processed separately by cropping the text area first.
