Object Class (Pet Head)

🎯 Detection Task: Pet head detection using bounding box annotations in Pascal VOC format. Each image contains one pet head with precise bounding box coordinates.

πŸ“ Bounding Box Properties β–Ό

Size Statistics

Mean and median width/height of bounding boxes

Aspect Ratio Distribution

Distribution of wide, square, and tall bounding boxes

Area Distribution

Distribution of normalized bounding box areas

Size Categories

COCO-style size categorization (small/medium/large)

πŸ“Š Key Insights:
  • Size Categories: Based on diagonal length (small: <32px, medium: 32-96px, large: >96px)
  • Aspect Ratios: Wide (>1.5), Square (0.8-1.2), Tall (<0.67)
  • Normalized Areas: Bounding box area relative to image area

πŸ—ΊοΈ Spatial Distribution β–Ό

Position Heatmap

Density map of bounding box center positions

Center Bias Analysis

Distribution between center and edge regions

3x3 Grid Distribution

Distribution of bounding boxes across image regions

🎯 Spatial Analysis:
  • Center Bias: Tendency for objects to appear in image center
  • Position Heatmap: Visual density of bounding box centers
  • Grid Analysis: Distribution across 3x3 image regions

βœ… Quality Analysis β–Ό

Quality Metrics

Overall Quality Score: Excellent (1.00)
Invalid Boxes 0
Tiny Boxes (<100pxΒ²) 0
Large Boxes (>90% image) 5
Extreme Aspect Ratios 0
πŸ” Quality Indicators:
  • Invalid Boxes: Negative dimensions or zero area
  • Tiny Boxes: Too small for reliable detection
  • Large Boxes: Cover most of the image (potential annotation error)
  • Extreme Ratios: Very wide or very tall boxes (ratio >10 or <0.1)
