original image
I think recognize the digits from this image would be really easy, but it just can't be recognized by tesseract and a lot of online OCR. Then I process it like this.
process image
Unfortunately it still can't be recognized by the tesseract.
My tesseract parameter:
tesseract input output digits -psm 7
That only returns a single dot .

The images are too small for it to properly work. I took your images and simply scaled them up to a height of 50px (constant resolution) and ran
tesseract input output -psm 7
My output resulted in
4 5 3 6 9 8 7 2 1 0
I did the same with your single 4, and before it got a . character as you did. Resized it and it worked fine.
Depending on your circumstances you may need a command line image resizing utility such as Imagemagick to process them.
