[Release] PSPuht V1.1.0

[mcidclan]

Hi everybody,


PSPuht (for psp ultimate head/hand tracker), is based on image processing.

It uses filters.
It identifies pixels values in the ycrcb colorimetric space.
It evaluates the position of a cloud of black pixels in a black & white image.

What's new in V1.1.0


Poc in video : http://www.youtube.com/watch?v=aNF9ids7FjU

This version is greater flexible and give better performances with
a tracking more tolerant to noise/parasites.

- A single allocation is necessary to initialize the buffers.
Allocate 0x22240 bytes for a direct rendering (No medium filter applied).
Else allocate 0x34E40 bytes if you want to apply the medium filter.

myUht-> initBuffer (Bwork, false, false) / / the second parameter indicates if seek to do a direct rendering. The last parameter indicates if the buffer RGB_565 shall be used or not.


- Ability to apply a grid of pixelization on the black pixels cloud. (corresponding to the tracked entity.)
This grid allows the elimination of parasites. You need to set the size of a grid cell, and give a tolerance relating to the pixels outside the cloud.

myUht-> setGrid (8, 32) / / grid cell size = 8; 8 * 8 pixels = 64; 64 / 2 = 32.
Tolerance to the pixels outside the cloud is 32.


- Ability to define minimum dimensions of the cloud pixels (corresponding to the tracked entity).
myUht-> setMinDim (20, 20); xMin = 20 yMin = 20 (width, height)

You can download it here : PSPuht V1.1.0
the archive should not be more than 210 ko

Sorry for my english :s

So this locates the heads and the hands ?
Damn i can't try it cause i don't have go cam.

[Mr_Shizzy]

I take it you used this lib:
Go! Cam Libs
to code this?

[thecobra]

It looks cool(Atleast in the Video) but like nickxab i don't have go! cam

Can you make a version that find the head,hand any other part on a regular pic. so people can make a picture comparison on two image and locate their position :) That be cool and MAYBE useful for people doing projetc based on that


P.S Good Work

Hi,

So this locates the heads and the hands ?
Damn i can't try it cause i don't have go cam.

In fact (at now) PSPuht locates pixels that are likely to belong to the skin.

I take it you used this lib:
Go! Cam Libs
to code this?

Sorry, I'm M-cid from mcidclan and we are talking about the same library.
This is an update of PSPuht (for PSP ultimate head/hand tracker). v1.0.0 to V1.1.0 :)

Can you make a version that find the head,hand any other part on a regular pic

It's possible, but it may require significant cpu resources.

uhhh nice move on psp
cant wait what ppl do with this

Really? it take more resources to scan a regular image for those skin like pixel then on the fly using a camera? wow that i did not know but it still be cool. Maybe people can use it like a game or something. Maybe for a "You Must have a hand picture with you to get in;Login feature" ;). Anyway Cool Project, keep up the good work

Sorry, i did not understand, you'r right. ;)
And in the case where we use a regular image from MS, CPU resources would not be a problem too, because the display would not be in real time. But it would take more resources than camera pictures can take. Because of images dimensions.
