Pixim Introduces Eclipse CDK for Biometric and Machine Vision Applications

Pixim Inc., a provider of image sensors and processors for enterprise security cameras, introduced its Eclipse camera development kit (CDK), a special-purpose video camera design based on Pixim's Digital Pixel System technology that uses ambient light rejection to deliver consistent monochrome images under all lighting conditions, for biometric and machine vision applications.
Changes in ambient lighting - including uneven illumination, shadows, reflection and glare - confuse machines into interpreting images incorrectly. The images made possible by the Eclipse CDK allow for the kind of consistent, identifiable edges and contours that are crucial for the effectiveness of applications such as facial capture, machine vision and a range of other image-based biometrics and video analytics.
Pixim's Eclipse technology works through a unique method of real-time image subtraction to perform ambient light rejection. The Eclipse ambient light rejection technology emits IR light, capturing image pairs, one containing ambient light and one with ambient and IR illumination. It then performs image subtraction in real time to eliminate the ambient light from the image. By canceling out the ambient light, Eclipse eliminates confusion within video analytics algorithms in identifying actual image boundaries, shapes and contours.
Situations that will benefit from Eclipse-based ambient light rejection cameras include:
‧ Biometrics applications
- Facial recognition
- Iris recognition
- Eye tracking (including glint detection)
‧ Security
- Access control (e.g., airports, government offices, research facilities)
- Perimeter control (e.g., borders, warehouses, ports)
- ATM video recordings
- Choke points
- Image-based alarms
- Trip wires
‧ Machine vision
- Robotics
- Structured light
