box_threshold float

Default value: 0.4

Adjusting the box_threshold value, ranged between 0 to 1, affects the detection of text in documents. A lower value allows the model to detect more bounding boxes, while a higher value reduces detection sensitivity. It is recommended to start with the default value of 0.4 and gradually increment the value by 0.1 until achieving the desired result for the document being used. (Number between 0 - 1)
