Lots of ways. For starters:
- Use descriptive variable names. Like not sz but [rows, columns, numberOfColorChannels] = size(rgbImage); No one wants to look at an alphabet soup mess of a code.
- Use LOTS of comments. You have far too few of them. I'd triple the number, at least. In my code I make sure I have at least 30% of the lines of code have a comment on them. See attached comment counter program.
- Don't use MATLAB function names, like "image" for the names of your variable or it could cause problems. If in doubt or you want to check, use "which -all image"
- Use either camelCase or snake_case. So Inputfolder becomes inputFolder. Use lower case for all variable names unless you're starting a new word and in that case capitalize the first letter of the next word.
- Use fullfile(folder, baseFileName) instead of messy stuff like ['F:\Projekt Handgeste\FinalBilder\zwischenspeicher\0\',num2str(i),'.jpg']; fullfile() has the advantage of not having to worry about whether your folder has a trailing slash or not or what direction of slashes to use. It figures it out. You can construct a base filename with sprintf(): baseFileName = sprintf('%2.2d.jpg', i);
- Don't use i or j as loop iterators since they can be used at the imaginary variable. Use k or row or something else.
- Don't use jpg when doing digital image analysis (unless you're trying to figure out how to make the JPG compression artifact less horrible. Use PNG instead - it's become the defacto world standard now for image analysis.
- To get separate color channels, use [r, g, b] = imsplit(rgbImage);
