I NEED TO IMPLEMENT FACE AND WRITING RECOGNITION FROM DIGITAL PICTURE (MADE BY CAMERA) INTO MY PROJECT. I TRIED TO FIND ANY SDKS FOR THE PURPOSE BUT NOT SUCCESS. ANY ONE WORKS ALREADTY WITH THAT? I NEED TO MAKE RECOGNITION OF FACES AND TEXT FROM PICTURE TAKEN BY CAMERA.
You failed to recognise that your CAPS LOCK key is stuck!
That, and the fact that a '51 might be slighly underpowered for image processing.
If it is just Turing-complete, it's just a question of giving the little dear the needed time. Why hurry?
Why hurry?
You don't want the poor person waiting to be identified by your face analyzer to starve in the meantime, do you?
But the requirements should already cover expected response times - how fast to get a match. How fast to report a failed match. How accurate the matching is expected to be etc.
And these requirements will then control amount of time, money, equipment etc.
The OP must of course already have considered if the aim is a 1-second response time, or if it is ok to spend a day/image. I'm also confident that the OP has already considered exactly how the images will be made available to his software. If he will build a frame grabber for analog video, or if he will connect a USB camera to his USB host-capable 8051 or if he will use the 8051 with an Ethernet interface.
The all-capitals request clearly shows that the OP is a serious person who are fully committed to spend whatever time and efforts that are required to produce a well-working solution in an economical and efficient way. If he thinks a 8051 is fast enough for the task, then I must assume that he knows better than me what the requirements are.
YES
Still not fixed that CAPS LOCK, then?
