Question

I want to use face.com face detection API (send an image to a server and get back an xml string result).

I use urlread() and it cannot upload an image file.

the code:

fid = fopen('T000.jpg');
im  = fread(fid,Inf,'*uint8');
fclose(fid);

urlread('http://api.face.com/faces/detect.xml','post',...
        {'api_key'      , MY_CODE,...
         'api_secret'   , MY_SECRET,...
         'detector'     , 'Normal',...
         'attributes'   , 'all',...
         'file'         , im}) 

But it returns an error because MATLAB tries to encode the image as url.

Note: when I use an image on the web it does work (since no file is uploaded).

urlread('http://api.face.com/faces/detect.xml','post',...
        {'api_key'      , MY_CODE,...
         'api_secret'   , MY_SECRET,...
         'detector'     , 'Normal',...
         'attributes'   , 'all',...
         'urls'         , 'http://0.tqn.com/d/beauty/1/0/x/3/1/halle_berry_pixie.jpg'}) 

Answer 1

I found an answer. An alternative implementation to urlread() on the File Exchange.
