Function remove_overlap_blocks 

pub fn remove_overlap_blocks(
    elements: &[LayoutBox],
    threshold: f32,
) -> OverlapRemovalResult<LayoutBox>

Removes overlapping layout blocks based on overlap ratio threshold.

This follows standard overlap removal implementation in layout_parsing/utils.py. When two blocks overlap significantly:

• If one is an image and one is not, the image is removed (text takes priority)
• Otherwise, the smaller block is removed

Arguments

• elements - Slice of layout elements to process
• threshold - Overlap ratio threshold (default: 0.65) If intersection/smaller_area > threshold, blocks are considered overlapping

Returns

OverlapRemovalResult containing kept elements and indices of removed elements

Example

use oar_ocr_core::processors::layout_utils::{remove_overlap_blocks, LayoutBox};
use oar_ocr_core::processors::BoundingBox;

let elements = vec![
    LayoutBox::new(BoundingBox::from_coords(0.0, 0.0, 100.0, 100.0), "text".to_string()),
    LayoutBox::new(BoundingBox::from_coords(10.0, 10.0, 90.0, 90.0), "text".to_string()),
];

let result = remove_overlap_blocks(&elements, 0.65);
assert_eq!(result.kept.len(), 1); // Smaller overlapping box was removed
