Judging from your question about pdftotext.exe, I assume you are using Windows. I believe
all the available filters are included with the Swish-e Windows installer. The list is
fairly modest. Look at the filters/swish-filter-test script in the distribution.

As far as OCR on jpg files, I do not of any filter for that. The Swish-e filters just use
other, 3rd party programs to normalize non-text formats into something txt/html/xml for
Swish-e to parse. So if you can find a piece of software that does the OCR, you can write
a filter for it for Swish-e.
