Detection¶
Perform classification and localization for multiple (unspecified) instances
Hard to solve with techniques used for localization, as we need variable sized outputs
Approaches¶
- Brute-force Classification: Keep running classification for sliding window at different positions; computationally-expensive
- Histogram of oriented gradients
- Deformable parts model
- Region proposals
- Class -agnostic object detector
- Look for "blob-like" regions that are likely to be foreground containing objects
- Search techniques
- Selective search
- EdgeBoxes
Datasets¶
- Pascal
- ImageNet Detection
- Microsoft Coco
