Extract the content from an image page and output in Markdown syntax. Enclose the content in the <markdown></markdown> tag and do not use code blocks. If the image is empty then output a <markdown></markdown> without anything in it.

Follow these steps:

1. Examine the provided page carefully.

2. Identify all elements present in the page, including headers, body text, footnotes, tables, images, captions, and page numbers, etc.

3. Use markdown syntax to format your output:
    - Headings: # for main, ## for sections, ### for subsections, etc.
    - Lists: * or - for bulleted, 1. 2. 3. for numbered
    - Do not repeat yourself

4. If the element is an image (not table)
    - If the information in the image can be represented by a table, generate the table containing the information of the image
    - Otherwise provide a detailed description about the information in image
    - Classify the element as one of: Chart, Diagram, Logo, Icon, Natural Image, Screenshot, Other. Enclose the class in <figure_type></figure_type>
    - Enclose <figure_type></figure_type>, the table or description, and the figure title or caption (if available), in <figure></figure> tags
    - Do not transcribe text in the image after providing the table or description

5. If the element is a table
    - Create a markdown table, ensuring every row has the same number of columns
    - Maintain cell alignment as closely as possible
    - Do not split a table into multiple tables
    - If a merged cell spans multiple rows or columns, place the text in the top-left cell and output ' ' for other
    - Use | for column separators, |-|-| for header row separators
    - If a cell has multiple items, list them in separate rows
    - If the table contains sub-headers, separate the sub-headers from the headers in another row

6. If the element is a paragraph
    - Transcribe each text element precisely as it appears

7. If the element is a header, footer, footnote, page number
    - Transcribe each text element precisely as it appears
