Issue with Partial Detection of Pages by Nougat OCR

[SaimonDahal-02]

Some pages are not being fully detected by the Nougat OCR model. In many cases, only half of the content on a page is detected, while the rest is skipped. However, for other pages, the detection works perfectly fine.

Steps to Reproduce:

• Convert the PDF into images (one image per page).
• Process each image using the Nougat OCR model individually.

• Observe that some pages are partially detected, while others are processed correctly.

  (This is the notebook I'm following for inference )

  Example Results:

• First Example: For this page:

 ```
 ## Answers (LC2020 HL, P2):
 1. \(0\); \(A\), \(B\) and \(C\) are collinear [0, 4, 7, 11, 15]
 2. \(33\cdot 435^{\circ}\)[0, 4, 7, 11, 15]
 3. \(9\)[0, 4, 7, 11, 15]
 4. \(x^{2}+y^{2}+4x-21=0\), \(x^{2}+y^{2}-8x-9=0\)[0, 4, 7, 11, 15]
 5. \(6\cdot 44\) m [0, 4, 7, 11, 15]
 6. \(k=9\)[0, 4, 7, 11, 15]
 7. \(\frac{5\pi}{3}\), \
 ```

• Second Example: For this page:

   ## Answers (LC 2019 HL, P2):
   1. (i) \(\frac{48}{95}\) [**0, 4, 7, 10**], (ii) \(\frac{88}{969}\) [**0, 4, 5, 8, 10**]
   2. 1400 [**0, 4, 7, 10**]
   3. Show [**0, 4, 7, 10**]
   4. (i) \(mx-y-6m=0\) [**0, 2, 5**], (ii) \(P\bigg{(}\frac{18m+25}{3m+4}\), \(\frac{m}{3m+4}\bigg{)}\) [**0, 4, 7, 11, 15**]

  Expected Behavior: The OCR model should consistently detect all parts of each page, rather than only detecting part of the content.

  Question: Is there any preprocessing that needs to be done to ensure complete page detection? Or are there specific parameters that should be adjusted in Nougat OCR to improve the results?
