neg data set #26

Hi,

For non-face images, the resized images are stored in neg.hds. However, during the training, neg.CalcFeatureValues() is trying to access neg.imgs, neg.imgs_half and neg.imgs_quarter which are not initialized.

For me it looks like a bug. Please correct me if I am missing any thing here.

Thanks and Regards,

@jayachandrad neg.hds is optional, they are non-face patches not the background images. We always need background images to mining hard negative samples. Actually, when the program starts, we first load face images and background images to pos.imgs and neg.imgs, then, if there's an optional initial negative samples which are manually prepared, we load these images to neg.hds and will use them to mining hard negative samples at first.
