Model answer: To solve this task, we need to analyze the given Sudoku grid and extract the digits into a 9x9 text format grid. The given Sudoku grid is: ``` 4 8 6 7 1 7 2 9 5 4 9 7 4 3 7 5 8 8 9 6 5 9 4 1 7 8 7 6 4 2 7 ``` Let's fill in the missing values with a dot (.) to represent empty cells. 1. First row: `.4.8.` -> `.4.8.` ( missing values are represented by dots) Actual first row: `.4.8.` 2. Second row: `6.7.1` -> `6.7.1.` Actual second row: `6.7.1` 3. Third row: `72.954` -> `72.954` Actual third row: `72.954` 4. Fourth row: `.97.43.` -> `.97.43.` Actual fourth row: `.97.43.` 5. Fifth row: `.75.8.` -> `.75.8.` Actual fifth row: `.75.8.` 6. Sixth row: `.89.65.` -> `.89.65.` Actual sixth row: `.89.65.` 7. Seventh row: `94.17.8` -> `94.17.8` Actual seventh row: `94.17.8` 8. Eighth row: `.76.4.` -> `.76.4.` Actual eighth row: `.76.4.` 9. Ninth row: `..2.7..` -> `..2.7..` Actual ninth row: `..2.7..` Now, let's put these rows together to form the 9x9 grid in text format. The final answer is: ``` .4.8. 6.7.1 72.954 .97.43. .75.8. .89.65. 94.17.8 .76.4. ..2.7.. ```

Model answer: I can't reliably read all digits from this image (some are too small/blurred at this size). Could you upload a clearer / higher-resolution crop of just the Sudoku board (no extra border), or zoom in so the cells and digits fill the image? That will let me extract the 9x9 grid accurately.
GPT-5 Nano
Model answer: I’m happy to extract the 9x9 grid, but the current image is a bit too small for reliable digit detection. The digits on the Sudoku are small and close to the grid lines, which makes accurate OCR difficult. Would you be able to provide: - a higher-resolution image, or - a cropped image that focuses just on the Sudoku grid (without the outer decorations)? If you’d prefer, I can attempt a best-effort read now and return a 9x9 grid, but please note it may contain errors.

Model answer: ```python def extract_sudoku_grid(image): """ Detects and extracts digits from a Sudoku puzzle image. Args: image: A PIL Image object representing the Sudoku puzzle. Returns: A string representing the 9x9 Sudoku grid in text format, where each row is a string of 9 characters. """ grid = [] for i in range(9): row = "" for j in range(9): pixel_value = image.getpixel((j, 8 - i)) # Image coordinates are (x, y) if pixel_value[0] > 190: # Check if the pixel is dark enough to be a digit digit = pixel_value[0] - 220 row += str(digit) else: row += "." grid.append(row) return "\n".join(grid) # Example usage (assuming you have the image loaded as 'image'): # from PIL import Image # image = Image.open("sudoku.png") # sudoku_grid = extract_sudoku_grid(image) # print(sudoku_grid) ``` **Explanation:** 1. **`extract_sudoku_grid(image)` function:** - Takes a `PIL Image` object (`image`) as input. - Initializes an empty list `grid` to store the rows of the Sudoku grid. - Iterates through rows (outer loop) and columns (inner loop) to build the grid. - **Pixel Retrieval:** `image.getpixel((j, 8 - i))` retrieves the color value of the pixel at column `j` and row `8 - i`. This is because the `y` coordinate in an image starts at 0 at the top, but the Sudoku grid has the top row at `y=0`. Subtracting `i` from 8 maps the row index `i` to the corresponding `y` coordinate. - **Digit Detection:** - `if pixel_value[0] > 190:`: This condition checks if the pixel's RGB value (stored as a tuple `pixel_value`) is dark enough to represent a digit.

Model answer: Let's extract the digits from the Sudoku puzzle given in the image. Here's the 9x9 text representation of the Sudoku grid, where empty cells are represented by a dot (.): ``` 48....1. .27...4. 97..5.3. .7..8.5. ..96...7 41.7...4 .5.....8 6.5.1.... .2.6.4.7 ``` In this representation, a dot (.) indicates an empty cell. This representation assumes the correct order from top-left to bottom-right of the board. Make sure this matches the original structure of the Sudoku puzzle you provided. If there is any discrepancy, please clarify or provide more details.
