Software package called ImoVu - Deep Learning architecture for image processes that imitates human recognition

Vision for Embedded Systems
97% accurate
140 FPS on i7 processor
Ambient Intelligence (AML) - Electronic environments that are sensitive and responsive to the presence of people.
Minimal required resolution for a face: 50x50px, Ideal 70x70px
Does not use FACS
Uses OpenCV open source software to identify faces and for some devices, sometimes falls back to the devices facial recognition
This software is not useful for things or places (only people)

Allows for
- Access to Hard to reach places
- Large coverage area
- Eye Level
- Improved angles

Wind - a vector velocity field with spatial and temporal variation
Wind has structured (predictive) and random properties (turbulence) that are difficult to model
State
- Attitude (Roll, Pitch, Yaw, Roll Rate, Pitch Rate, Yaw Rate)
- Attitude Rates
- Position
- Velocity
Other possible states
- Wind Paramters
- Height over ground
- Battery energy
- gyro bias
- accel bias
Attitude Estimation
- Stabilized Sub Platform
- Whabba's problem
- Integration
- Combined
Contempory Sensors
- Gyros
- Accelerometers
- Magnetomers
- GPS Baseline
- Thermopile
- Elecstratic potential
- Opical sensors

Drones are named from the first unmanned aircraft in Britain during WW1
[1]
FAA cant regulate anything congress doesn't give them authority over
Required for an aircraft to be regulated
- Approved Pilot
- Aircraft Certificate
Code of Federal Regulations (91.113) - you must be able to see and avoid other aircraft (thus-- you need a 333)
COWA - Certificate of Waiver or Authorization
AC - 91.57A new AC that regulates RC hobby
AC's are not regulatory
CFR 14 91.13 Careless and Reckless Operation
- Aircraft operations for the purpose of air navigation. No person may operate an aircraft in a careless or reckless manner so as to endanger the life or property of another.
- Don't do stupid things that put people in the air at risk.
14 CFR Part 107 creates new rules for small unmanned aircraft systems
Examples
- CNN is looking at tethered aircraft (tether provides power) - Power Electronics 01
- Railroad wants UAV to monitor tracks in front of trains looking for issues with tracks
- Farmers are looking for ways to safely use UAV without LOS by monitoring airspace for incoming commercial aircraft
FAA - Department of Transportation interactions take a lot of time
Most insurance policies will not cover accidents caused by commercial use of drones
Some companies with 333 exemptions are suing companies operating without the proper exemptions

Goksel Dedeoglu, Founder PercepTonic, LLC
Computer vision algorithms analyze images to extract information about the world (allowing machines that perceive)
- Size and shape
- 3d position
- Identity
- Expression
- Location
- Motion
- Illumniation, weather, etc.
Two things relevant for drone operation:
- Motion
- Depth
Inertial sensors
- Identifies key points
GerbilBall is a safety sphere enabled by real-time depth sensing
- Stereo-based
- Has limitations on how close the two objects can be to each other
- Can have as many cameras as needed to create a realtime look in all directions (expensive)
- For objects that don't move often, may be cheaper to build an internal model of what has been seen
Best guess for power efficient vision computation is heterogeneous and multi-core architechtures
Examples
- Fire Phone makes good use of computer vision with multiple cameras
- Dyson 360 Roomba
