In the project that I'm currently working on, we often use so called "key points" – in image processing these are characteristic points (interest points) on images.
I'm wondering – is it okay to use "keypoint" as a single word instead of "key point"?
(PS I'm not into language-stuff, so I don't know what are the appriopriate tags for such question.)

In technical or academic writing it is always acceptable to use the correct jargon terms for the field.
A quick search on Stack Overflow suggests that "keypoint" as a single word is in reasonably common use.
On the other hand, google searches combining "keypoint" or "Key point" with other image processing terms seem to suggest "keypoint" is somewhat more commonly used. Both are used in academic papers.
If this is for academic work you might want to copy what your instructor or lecturer does.
