I have the below construction and doubting the correct usage of prepositions.

This paper shows a comprehensive approach that takes into account the knowledge about the shape of man-made object for individual object segmentation from point data.

Do you think that I should use about with knowledge? Any rectifications please.

Yes, in this context knowledge should be followed either by about or of, because the sentence specifies a particular field of knowledge.

Also, you should have an article in front of man-made object (or use the plural form objects).


The sentence is similar to the following ones:

He has a wide knowledge of painting and music.

There is a lack of knowledge about the tax system.

In both the cases, you cannot remove of/about.

? He has a wide knowledge painting and music.
