Author: Farin Kulapichitr(ictfarin@gmail.com) This plugin is used as a preprocessing step before OCR to adjust document tilt to the optimal angle. To determine document tilt, it detects and utilizes the inclination of lines contained within the document image. Technical Information: It uses the Fast Line Detector algorithm provided by the opencv-contrib-python package. For more detailed information, please refer to the official documentation page: : https://docs.opencv.org/4.x/df/ded/group__ximgproc__fast__line__detector.html |
Input(Properties)
|
Parameter Name | Description |
|---|---|
Input File | Path of the input image to process (e.g., path\input.png). |
Output File | Path of the output image (e.g., path\output.png). |
Length Threshold1 | Minimum line length used for tilt detection (*px). |
Distance Threshold1 | The length at which broken lines are permitted to join (*px). |
The following two parameters will be processed only when the slope falls within the range of Max Angle and Min Angle. | |
Max Angle | Maximum accuracy allowing adjustment processing (*percent). Will not handle excessive tilts. |
Min Angle | Minimum accuracy allowing adjustment processing (*percent). Will not process small tilts. |
Min Rotate | If the image is tilted beyond the specified angle in the adjustment results, it will not be output. |

Return Value
No specific Return type for this plugin (neither String, CSV, nor, File).
