I am using quite a few images from other neuroscience papers or medical books in my paper. I went through the recommended procedure of writing to the authors and copyright owners about six weeks ago. All the authors wrote back right away and said ok to use. The copyright owners: journals and medical publishers have for the most part not replied. Except some automated replies. One journal publisher did reply and asked for a copyright fee. Another wanted a fee to fast track the copyright application as well as copyright fee. In light of this blank wall of approval I am thinking i could use some of my graphic skills to "extract data" from images ? That is i do a line drawing of the relevant parts from the image using a graphics tablet. I'll then put a reference under the image..(Line drawing of ----- ) I was told here that i could "extract data" from images and not break copyright. SO i guess what i'm asking is making a hand written line reproduction extracting data, or am i still breaking copyright ?
