Video Compression and Motion Compensation Toolkit

Advanced video processing techniques implemented in MATLAB, featuring frame prediction, motion compensation and object removal.

Features

Video Preprocessing

• Format Conversion: MP4 → Uncompressed AVI (optional)
• Frame Rate Adjustment: 60fps → 30fps (optional)
• Resolution Handling: Default 640x640 (configurable)
• Color Support: RGB & Grayscale

Compression Techniques

Basic Frame Prediction

• I-frames & P-frames sequence
• Error frame visualization
• Lossless RLE encoding
• Frame differencing

Advanced Motion Compensation

• Hierarchical motion estimation (64x64 blocks)
• 32px search radius
• MAD cost function
• Multi-level pyramid refinement

Object Removal

• Motion-compensated inpainting
• Restricted block matching
• 16x16 macroblocks
• Background preservation
