What This?

This repo contains the code for the final optimazation task of the IVC Lab at TUM. I decided to create a codec that relies on an original idea, which is to treat subframes of images differently depending on the information that is contained in it. For more information refer to the 3 min presentation in the "Alexander_Prommesberger_Final_Opt.zip".

To Run the Code

1. Open Alexander_Prommesberger_FinalOpt.m

2. Select the path to your images and add myfunctions, IVC Huffman and Data for plot folders to path!

3. Press Run to run with default Parameters --> only 8x8 Prediction is used! h_fac =5; qScales = [0.07, 0.2, 0.4, 0.8, 1.0, 1.5, 2, 3, 4.1, 4.5];

4. Play arount with the parameters, describtion in Alexander_Prommesberger_FinalOpt.m

   • If 4x4 PRed should be used: h_fac = 1.05 is recommended --> qScale should be below 0.5! for ex. qScales = [0.07, 0.2, 0.4];
   • EOB should not be under 4000, could raise decoding problems!
   • max_displacement=4 is good value, if lower, bpp could raise, run time problems if to high !

To Plot the Curves:

Go into Data for Plot and run PlotSkript_FinalResults
