Panel a: Visualization of the Solar Orbiter’s trajectory based on the complete FSI dataset. Panel b: Compression ratio trends over time at a fixed quality level corresponding to a PSNR = 88 and PSNR = 75. Color coding indicates different compression methods. RICE and lossless compression (GZip) have fixed compression ratios and are used as baselines for reference. Advanced lossy compressors demonstrate significant advantages in compression ratio. Panel c: Visual comparison and difference maps between the original image (acquired on April 5, 2024) and the reconstructed images from five compression algorithms. All difference map display ranges were set to ±50 for consistency in this work.
