Image Compression Question SVG problem (Huffman & LZW)

I am doing a project in matlab which compress an image file usign the two algorithm.

I am using a GUI and it needs to be displayed first before compressing. But it's not showing in my GUI (axes). I can only compress image format like (PNG, JPEG,BMP,TIFF,GIF) but not SVG file.

My question is, is it possible to compress an .SVG file for my project? or is there any way to do it? or is it achievable?

Wait?! can LZW compress JPEG? please share me the code, am conducting my MSC in IT thesis entitled "Improving LZW Image compression". thanks in advance

You can find the code in file exchange. I got it there and edit some code to make it work for image files

Yes, LZW can compress JPEG. The question would be whether it can do a good job of it.

You should differentiate between .jpg files (which are probably really JFIF https://en.wikipedia.org/wiki/JPEG_File_Interchange_Format) and the JPEG block of coefficients, which is a block that can be embedded in a number of different image file formats. .jpg files have headers and comments and so on and so generally have something compressible in them. JPEG blocks of coefficients are already fairly compact and would not be expected to compress well.

imread() cannot read .svg files. SVG are vector graphics that need to be interpreted.

See the discussions at https://www.mathworks.com/matlabcentral/answers/58280-input-vector-graphics-into-matlab#answer_70543 and see https://www.mathworks.com/matlabcentral/fileexchange/66554-svg-import-export which parses SVG files but does not create an image from them.
