      • Forward propagation
        11/22/14
        So the forward propagation is ready and working. Unfortunately, due to memory constraints, I had to change the network structure a bit.

        One 60x60 sample is processed by a 2x2 group of processors. Given that Parallella can have 4x4 or 8x8 grids, this allows 4 or 16 groups respectively work

      • As a very quick update
        11/13/14
        Within the last week or so
        - downloaded the datasets that were used in 300 Faces in the Wild.
        - implemented basic functions like image pre-processing, convolution + maxpooling etc.

        Still not sure what to do with unshared convolution, plus there are some other questions that were

      • The board
        11/02/14
        So the board works fine, and apparently worked fine all the way.

        Except for the USB bug. Apparently to get USB working I'll need to vandalize a USB cable.

        Might try that some time, but for now I've connected it to my home router and SSH'ed into it. Examples run f

      • Some papers I've been reading
        10/30/14
        Last week was quite busy with midterms (plus there was nobody in the lab, and I don't have keys :) so I wasn't able to start fiddling with the board. Instead, since there is an obvious winner among the algorithms, I decided to start looking at it.

        The basis is described here: ht

        The image set can be downloaded from here.
        Full test results as Excel file.

      • Test results
        10/15/14
        It has taken more time than I anticipated, partly because I wasn't able to do much during IAC, partly because the existing face detection demos are often hard to find/hard to setup/no longer can be found where they were supposed to be etc. As a result, out of the programs I found, I was only ab

      • Final dataset
        10/01/14
        The final dataset composition:

        120 images taken in the lab
        90 images of dolls from internet
        10 photos from actual rescue missions
        80 images of rubble, wood, boxes etc.
        -------
        300 in total.

        Will post the info about the testing when I return from the Int

      • Forming image set
        09/24/14
        Images of the victims taken yesterday, total ~140, ranging from easy to trickier.



        If I cannot find enough pictures online to increase the set size to at least ~500, I will need to buy a few more dolls, because that is about all non-repeats I can get with these three.

      • It works!
        09/18/14


        Well, kinda. Good news: it boots.

        Bad news: usb doesn't work. Todo: double check the drivers.

        Dolls from Value Village, seemed the most similar to the ones used in the competition.
