I was wondering if DeepStack supports any other image formats than jpeg?
I know jpeg is easy, but I have some images in .png format, and i want to know if I have to convert them first before feeding them into DeepStack.
I would also like to know if pre-processing the images is of any use (or are they processed internally?). I ask because I have a training database (used for other facial recognition experiments) which has faces cropped, converted to black and white, and histogram normalized.
When comparing, I usually convert the live image to BW, histogram normalize, then use the image for facial recognition. This gives good results in day or night mode. I don’t know if this is needed though, as I don’t know what internal pre-processing DS does.
Does colour information matter? or am I better using BW for everything?
