Hi!
Hope everyone is doing well! I am following YOLO example for inferences with my own dataset. I noticed the example had annotations in the format like below in a table format (imagefilename cloumn, and vehicle column).
While the annotations file that I have has a different format and I am struggling to convert to the similar format as above. When I import the json file, it converts the data into stuct, which I am not very familiar with other than looking up Youtube videos, and MATLAB docs.
This is the data from imported json file.
This has multiple categories and each bounding box is split into individual rows. It seems I will have to convert that into a table format for corresponding image. I can have multiple columns for different categories. Any suggestions?
Thanks!

You can use struct2table(): https://www.mathworks.com/help/releases/R2020b/matlab/ref/struct2table.html to convert structs to table. This shows how to access data in MATLAB's table: https://www.mathworks.com/help/matlab/matlab_prog/access-data-in-a-table.html

sure, I will post the solution once I get the detector working so I know the code can be used in the future.
