Occupancy sensor and luminance measurement for sunlight harvesting. Use case: Ignore security guard flashlight. Use case: Maintain light level even if reflective surfaces are covered with a black sheet.

Color Space for Embedded Vision, Part 2

Craig Sullender — Thu, 23 Jun 2011 22:03:09 +0000

I really did rush into the luminance options in Part 1. I'll take this opportunity to try to gain amnesty for when I make the same mistake again. But as for embedded vision, it will succeed when it delivers useful vision functions at a cost appropriate to the application.

Semi-Conscious: The consumer vision market is more real than you are.

Seriously does anyone really think we will have a breakthrough in consumer vision products using general purpose processors alone? Not breakthrough in the sense of "more people will have to buy our big hot chip."

Color Space for Embedded Vision

Craig Sullender — Mon, 13 Jun 2011 16:05:23 +0000

The components of a color space let us specify the reproduction of an image pixel by pixel. The quality of appearance each component describes--and how well it describes that quality--can determine the complexity, cost, and performance of our embedded vision system. Which color space is best for embedded vision?

Easy Eye: SiLabs 8051 + Camera

Image capture and 60fps color object targeting with an 8-bit microprocessor and a CMOS camera. The C8051F360 syncs to video from a digital camera, reads pixel values, makes decisions about objects in the scene, communicates by serial port, and drives displays or servos by GPIO.

Semi-Conscious: Consumer Vision

Sensor networks with cameras. $2 vision systems. Roombas that avoid dog poop. Machine vision people ask me "what do you want, object recognition with a PIC?" Yes. Why not?

RAW Pixel Diet

Craig Sullender — Mon, 16 May 2011 22:53:30 +0000

What type of input does a vision application need? Can we use pixel data straight from the camera's image sensor? Or does the application need pixel data processed by an image sensor pipeline (ISP) with color transformations and denoising?

Semi-Conscious: Hot FPGA Pixels = Surveillance?

Craig Sullender — Fri, 13 May 2011 00:03:56 +0000

Has not one seat in the circle of vision research been left vacant for a new approach? Come winter we enjoy the heat of FPGAs stuffed with cranky algorithms grinding through pixels to make .... the same pixels come out the other end.

Microchip – Let my robot see!

Computer Vision, Laser Ranging, and Servo Control on a Single-Wire Network A Microchip PIC directly sampling a video signal. 8 pins well used.

Semi-Conscious: GPU – Now you’re just mashing it.

CPU/GPU/FPGA/ASIC. General purpose processors that do everything slowly vs. specialized functions that do some things quickly.
