Use ECE style for CC images (Not footnote), link to CC pages.

Also fix sefref to not have the dot afterwards, only the heading itself has it.

 \subsection{Algorithms}
 Algorithms can be implemented simply using \LaTeX. An example of an algorithm is given in Algorithm \ref{alg:examplealg}. An input and an output for the algorithm should be assigned at the start. Equations or discussed methods can be referenced in the algorithm. Depending on one's needs the algorithm may be implemented in a higher level of pseudocode compared to one in Algorithm \ref{alg:examplealg}.

 \section{Use of images: Intellectual Property Rights}
 \label{copyright}
-Intellectual property rights (IPR) protect works, i.e. the authors and rights-holders of literary or artistic works that exceed the threshold of originality. These works include for instance texts, images, music and computer software codes. For this reason, figures found on the internet, for example, may not be freely used in theses. This section explains how they can be used and provides examples.

This section explains how they can be used and provides examples.
 
 The starting point is that the figures must be related to the text, i.e. the text must explain why the figure has been presented. The text must contain a reference to the figure. Use self-made figures (drawings, schematics, simulation or measurement result figures, photographs), if possible.

 If you use figures made by others, you must have permission from the copyright owner to use the figure. For instance, IEEE and many other publishers have an automated system for granting permission for theses. Mark the permission in the caption as requested by the right holder, e.g. “Reprinted with permission from [x] \textcopyright\ IEEE, 2022.”.
 
-Not all figures exceed the threshold of originality. These include, for example, scientific diagrams and flowcharts. Good research practices require that even in this case, the source is cited in the caption ("Figure from source [x]."). However, it would be best to ask for permission. Images with a CC licence are free to use, so long as the terms of use are followed [6]. Even then, the caption must mention the source (article, website, etc.) and that the image is CC-licensed, for example. ”CC BY 4.0 licensed image from source [x].”.

Even then, the caption must mention the source (article, website, etc.) and that the image is CC-licensed, for example. ”CC BY 4.0 licensed image from source [x].”.
 
 Based on the right to quote, it is possible to take a photocopy, screenshot or photograph of a work (not the original file) and publish it, citing the original source in the caption. A critical aspect of the right to quote is that the use of the image is relevant to the work, i.e. the image must be related to the subject, and it must be explained in the text (this applies to all images). Similarly, the source must be cited in text citations.
 
-Sometimes you may want to use someone else's original image idea as a basis for your own work. Permission is not required provided that your work clearly an amply edited version of the original. However, in accordance with good research practices the source must be declared in the caption (“Modified/Adapted/Redrawn from/Based on/Created using data from [x].”), depending on the extent of modification done to the original image. Should you only make minor edits, the permission is required.

 When searching for images through an internet image search, it is not always easy to find the rights holder from whom to request permission for use. Hunting for a permit can be a demanding task. The easiest way is to use images and figures from scientific articles as in these the rights holders are clearly declared.
