3/12 Original image

4/12 Image after thresholding

5/12 Practical use of the algorithm

6/12 How to solve the problem? image can be very large (hundreds of MBs) problem is loop oriented almost no data dependencies conclusion: dataflow paradigm (Maxeler)

7/12 Preparing data program takes an image and outputs a thresholded version of it image has to be in.bmp format (bitmap) size does not matter (it can be 1KB or 200MB)

8/12 Kernel code

9/12 The ultimate goal – Build completed ☺
