Content-Aware Image Resizing

1
Content-Aware Image Resizing

• Jack Breese
• Computer Systems
• Quarter 1, Pd. 7

2
A Comparison of Image Resizing

• Retargeting
• Scaling
• Seam-Carving

3
Retargeting

• Smaller portion of the image is scaled up to a
  different size.
• Aspect ratio cannot be changed without losing
  data.

4
Scaling

• Image size is increased or decreased by removing
  or adding pixels.
• Aspect ratio cannot be changed without stretching
  image.

5
Seam-Carving

• Lowest energy seam is duplicated or removed
• Content-Aware
• Changes aspect ratio without stretching important
  image data.

7
Problems of Seam Carving

• Faces must be manually identified and tagged in
  images to avoid distortion.

8
Project Status

• Reads in image files
• Outputs individual columns or rows of pixels
• Finds seams of bright pixels (semi-working)?
• Edge detection

9
Future Goals

• Quarter 2
• Implement actual image resizing
• Write system for tagging faces
• Begin work on simple face recognition
• Quarter 3
• Continue implementation of face recognition
• Quarter 4
• See Q3.
