Hi,
I am new to XMOS architecture. I would like to know if it is possible to implement any face recognition algorithm on this platform. How does it supports camera and other image processing functions.
Face recognition
It certainly is possible but you may have to use external ram for working with a respectable resolution image as the internal ram fills up very fast when you want to store images in it.
64kB per core is quite a lot really; you do have to be a bit careful, of course, and you certainly
have to _think_ about how you're using it. It's easily enough to store an image for this.

Well a 320x240 color image is already 150kB. I know that cause i had problems with a frame buffer for a LCD display. I'm guessing he wants a relatively high res camera to do it accurately
If you store it at 16 bits per pixel, sure. I am saying you don't need that :-)Berni wrote:Well a 320x240 color image is already 150kB.
Everything is always a tradeoff...
Yes I will be needing relatively high resolution image quality to get accurate results. I will be needing RAM also for storing face feature extraction templates.
In this forum only, I read there are issues with implementing external RAM. Does anyone has experience with it?

Well external SRAM works pretty nicely but you need a lot of pins to interface it.
