Study Notes

Passive and Active Compliance

Passive compliance utilizes mechanical properties like springs and dampers for flexibility and damping in robots.
Active compliance employs sensors and actuators to monitor and adjust contact forces and movements in real time.

Image Acquisition Techniques

Dynamic Range Extension: Enhances brightness levels captured in images beyond standard sensor capabilities, allowing details in both dark and bright areas.
Pixel Binning: Combines neighboring pixels to increase the signal-to-noise ratio, effectively extending dynamic range.
Multiple Exposure Fusion: Captures various exposures and combines them into a single image to preserve details in highlights and shadows.

Object Representation Methods

Geometric Representations: Focus on an object's shape and spatial attributes.
- Bounding Boxes: Defines rectangular boxes around objects using coordinates.
- Polygonal Meshes: Creates 3D structures from interconnected vertices and faces.
- Point Clouds: Represents surfaces as collections of 3D points from LiDAR or other reconstruction techniques.
Appearance-based Representations: Captures visual features like color and texture.
- Histograms: Shows distribution of colors or intensities within an image.
- Gabor Filters: Identifies specific textural patterns.
- Deep Learning Features: Utilizes CNNs to extract complex visual representations.
