- Add support for \(\) and \[\] delimiters in addition to $$ and $$- Make LaTeX delimiter configuration more flexible and user-defined
- Update configuration file to include LaTeX delimiter settings
- Modify OCR content generation to use configurable delimiters

- Add \textunderscore to the list of LaTeX patterns
- This allows the model to properly render underscore characters

- Improve \left and \right command handling in LaTeX formulas
- Enhance environment type matching for array, matrix, and other structures
- Refactor code for better readability and maintainability

- Refactor LaTeX left/right pair fixing logic for better balance
- Add environment detection and correction for common math environments
- Implement more robust whitespace handling and command substitution
- Optimize regex patterns for improved performance and readability

- Add functions to fix LaTeX left and right commands
- Implement brace matching and repair in LaTeX formulas
- Remove unnecessary whitespace and repair LaTeX code
- Replace specific LaTeX commands with appropriate alternatives
- Add logging for debugging purposes

- Preserve "\ " sequences during whitespace removal
- Add temporary substitution to prevent incorrect processing of "\ " sequences
- Restore "\ " sequences after removing unnecessary whitespace

- Replace get_device() function call with direct 'device' variable usage
- Simplify device configuration in OCR model initialization

- Add new Chinese OCR model (ch_PP-OCRv4_rec_server_doc_infer) for server-side use
- Update language support in app.py to include new Chinese model
- Modify models_config.yml to add new model configuration

- Automatically change to ch_lite model when using CPU for Chinese OCR
- This modification improves performance on CPU devices

- Remove OCR engine instantiation inside the loop
- Pass language directly to the table model instead of OCR engine
- Simplify code structure and improve readability

- Add '.jpeg' to the list of supported image extensions in app.py and read_api.py
- Update projects READMEs to indicate that web_demo is deprecated

- Remove specific Chinese font list and detailed font checking
- Add logging warning if no Chinese fonts are detected
- Make font checking more robust and less platform-specific

- Temporarily disable Chinese font check for Windows systems
- This change allows bypassing the font check when the required fonts are not present

- Modify `ocr_detect_all_bboxes.py` to return footnote blocks
- Update `pdf_parse_union_core_v2.py` to handle footnote blocks in line sorting and layout splitting
- This change improves the accuracy of layout analysis by considering footnote blocks separately

- Add text region handling in get_res_list_from_layout_res function
- Implement remove_overlaps_min_blocks function to handle overlapping blocks
- Update OCR region handling to include text regions
- Improve overlap resolution for all regions in layout results

- Update the range used to generate images_with_extra_info to match the number of images
- This fixes a potential IndexError when the number of images differs from the dataset length

- Change footnote detection threshold from 50% of page height to 30%
- Improve accuracy of footnote identification in PDF processing

- Add batch processing logs to track the progress of image analysis
- Display the current batch number, total batches, and the number of processed pages

- Remove unnecessary line breaks and adjust indentation
- Update function call to use named arguments for better readability
- Modify _do_parse function call to use MakeMode.MM_MD instead of

- Update batch processing logic for improved efficiency
- Refactor image analysis and inference methods
- Optimize dataset handling and image retrieval
- Improve error handling and logging in batch processes

- Comment out the line that updates det_count in batch_analyze.py
- Add a new OCR model configuration for Chinese (ch_lite) in models_config.yml- Update the Chinese OCR model configuration to use a different recognition model

- Change `bits` to `self._data_bits` for language detection
- This fixes the TypeError when opening PDF files

- Simplify aspect ratio calculation using direct coordinate subtraction
- Remove unnecessary list append operation
- Improve code readability and performance in table rotation detection

- Implement table orientation detection to identify if a table is in portrait mode
- Add rotation logic to turn portrait tables 90 degrees clockwise before OCR
- Update OCR processing to work with potentially rotated images
- Improve text box analysis to determine if a table is rotated

- Update predict_rec.py to check for NaN values in recognition results
- Replace NaN scores with 0.0 to ensure stability and consistency

- Add functions to calculate IoU, check if tables are inside each other, and merge tables
- Implement table merging for high IoU tables
- Add filtering to remove nested tables that don't overlap but cover a large area
- Update table_res_list and layout_res to reflect these changes
