  • Implement basic image transformations (e.g., grayscale conversion, image inversion)
  • Add simple filters (e.g., blur, sharpen)
  • Implement basic drawing functions (e.g., draw line, draw circle)
  • Add image resizing functionality
  • Implement basic image analysis (e.g., histogram generation)
