Engaging students in audiovisual coding through Interactive MATLAB GUIs

 

 

Description


This website complements the article "Engaging Students in Audiovisual Coding through Interactive MATLAB GUIs" by offering three interactive tools designed for hands-on exploration of coding concepts. These tools provide functionalities for:

  • Audio Coding: Experiment with different quantization schemes, analyze the impact on signal quality using SNR, and compare original, quantized, and error signals for auditory assessment.
  • Image Coding: Explore the trade-offs between compression ratio and image quality by comparing image domain and transformed domain coding. Measure compression with Huffman entropy and assess quality with RMSE.
  • Video Coding: Utilize block-based motion estimation to predict motion in videos. Adjust parameters and compare predicted images to originals using metrics like RMSE and PSNR. Analyze prediction time for efficiency considerations.
